Bundibugyo Ebola — DRC & Region

📍 Ituri Province, DRC (7 cumulative provinces incl. Sud-Ubangi · 63 of 167 health zones · WHO DON618 + CDC now confirm South Kivu has had no new cases since May 29 — six provinces show active transmission in the last 21 days) · Uganda (outbreak over) · France ⚠ WHO PHEIC Declared May 17, 2026 · Reaffirmed Aug 18 · Recommendations Updated Aug 24 📊 8,224 cases · 3,982 deaths (DRC govt. via ECDC running page, checked Oct 5, no newer count than Oct 2 refresh (data thru Sep 29) — up +108 cases / +58 deaths vs 8,116/3,924) 💉 Ervebo research vaccination under way in Ituri — the MSF-run BRAVO study (20,000 of 70,000 doses, 3,700+ vaccinated) · frontline compassionate-use campaign continues in Tshopo, Bas-Uele, Haut-Uele 🔬 Deadliest Ebola outbreak in DRC's history · 2nd-largest ever ✓ AI-verified from 15+ primary sources
Update (Oct 2): ECDC's running page now shows 8,224 confirmed cases and 3,982 deaths (CFR ~48.4%) - up 108 cases and 58 deaths on the 8,116/3,924 figure carried yesterday (the page's own text cites 53 new cases and 28 deaths since its previous report, so the step likely spans more than one refresh). Ituri accounts for 6,250 cases / 2,885 deaths (28 of 36 health zones) and North Kivu 1,570 / 931; 851 patients are in isolation and 78.7% of identified contacts are under follow-up (ECDC). Two operational shocks were reported Oct 1: an MSF humanitarian worker tested positive for Bundibugyo virus and is being medically evacuated to the Netherlands (MSF, via Arab News), and a key Ebola transit centre in Kigonze camp, Ituri, burned down on Sep 29-30 after thousands fled reports of soldiers searching the camp (UN News). The footprint is unchanged at 7 cumulative provinces and 63 of 167 health zones. Uganda's outbreak remains over (CDC: 21 confirmed and probable cases, 3 deaths; last case Jun 21). Three imported cases outside DRC (Germany, France) have all recovered; CDC reports no US cases and ECDC rates EU/EEA importation risk as very low. No licensed vaccine or therapeutic for BDBV exists and no PHEIC status change or MBP134/remdesivir result was found this run. The outbreak is now on Day 144 (PHEIC Day 142).

Five Factors That Separate This From Prior Outbreaks

New (Oct 2) — Case count rises to 8,224/3,982; an MSF worker is infected and a key Ituri transit centre is destroyed: ECDC's running page reports 8,224 confirmed cases and 3,982 deaths (Ituri 6,250 / 2,885; North Kivu 1,570 / 931), with contact follow-up at 78.7%. On Oct 1, MSF announced that one of its staff tested positive for Bundibugyo virus; the worker is being evacuated under strict protocol to a hospital in the Netherlands. Separately, UN News reports the Kigonze camp transit centre in Ituri burned down on the evening of Sep 29-30, in a camp that sheltered about 19,000 displaced people, after thousands fled amid reports of soldiers searching for weapons and suspected armed-group members; UN Ebola official Julien Harneis said the response loses capacity and investment. Sources: ECDC; MSF via Arab News; UN News.
Superseded (Sep 29) — ECDC updates national count to 8,067 confirmed cases and 3,901 deaths (CFR 48.4%), +177 cases / +102 deaths: ECDC's running page, checked directly this run, reports statistics as of Sep 28 (DRC Ministry of Health data): 8,067 confirmed cases, 3,901 deaths, 2,070 recoveries and 773 patients in isolation (down from 893 in the prior refresh). By province: Ituri 6,155 cases / 2,834 deaths; North Kivu 1,523 / 906; Haut-Uélé 331 / 139; Tshopo 43 / 16; Bas-Uélé 10 / 4; South Kivu 3 / 1; Sud-Ubangi 2 / 1. The +102 deaths on a +177 case rise implies a larger step than recent reports and spans more than one reporting interval, so it should not be read as a single-day jump. Uganda (20 cases, outbreak declared over Aug 25 after 42 days without a new case) and the three imported cases in the US and France (all recovered) are unchanged. WHO AFRO (page last updated Sep 22) still states no licensed vaccine or specific treatment exists for Bundibugyo virus, and CDC (Sep 23) reports no cases in the United States. No new trial results (MBP134, remdesivir) were found in named primary sources this run. Sources: ECDC; WHO AFRO; CDC.
Superseded (Sep 28) — South Kivu de-escalation CONFIRMED by two named primary sources (WHO, CDC), resolving yesterday's under-verification flag; no new national case count this run; ECDC's own Sep 28 update not yet published: This run fetched WHO's Disease Outbreak News DON618 (published Sep 25) and CDC's Ebola situation summary (updated Sep 23) directly, rather than relying on secondary wire coverage. Both state the same fact in the agencies' own words: WHO—“No new cases have been reported from South Kivu province since 29 May 2026,” with 48 of 63 health zones across six provinces (not seven) reporting at least one case in the last 21 days; CDC—“South Kivu has reported no confirmed cases since May 29.” Yesterday's brief carried this as a reported development sourced to an ABC News (Australia) feature quoting a DRC ministry daily report, and flagged it under verification because ECDC's own page had not yet reconciled it. With WHO's DON and CDC's situation summary now directly confirming the identical fact, this brief upgrades the flag from under verification to confirmed. Nuance that matters: this is a currently-active-transmission distinction, not a change to the cumulative outbreak footprint. The headline figures — seven provinces, 63 of 167 health zones — are unchanged, and South Kivu keeps its cumulative 3 cases / 1 death (Miti-Murhesa) on the historical list; what has changed is that WHO now explicitly states only six of those seven provinces have shown a case in the trailing 21 days. NO NEW NATIONAL CASE COUNT THIS RUN. ECDC's page still shows its Sep 25 (16:05) refresh with DRC data thru Sep 23 — 7,890 confirmed cases and 3,799 deaths, CFR 48.1% (WHO's own DON618 figure, more precise than the ~48.2% this brief had been carrying), 893 hospitalized in isolation, 1,966 recovered — and ECDC's own page states its next epidemiological update was due today, Sep 28, but had not been published as of this run. WHO, CDC and Africa CDC channels all still cite the same Sep 23 data cut. All other status flags unchanged: Ituri down about 26% and Haut-Uélé down about 15% over the last three weeks against a 73% rise in North Kivu, which continues to carry the highest provincial CFR in this outbreak at 59.7%; WHO AFRO regional emergency director Dr. Marie Roseline Belizaire's assessment that the outbreak is “still not under control” stands; case fatality among children under five remains above 60%; no WHO PHEIC status change; no new countries with confirmed cases; no new American or international cases; no confirmed Kinshasa transmission beyond the single travel-linked case from May; Uganda's own 2026 outbreak remains formally closed (20 cases / 2 deaths, end declared Aug 25, last patient discharged Jul 16); the MSF-run BRAVO Ervebo research vaccination study continues with 3,700+ vaccinated of a ~20,000 frontline-worker target; no PARTNERS (MBP134/remdesivir) results beyond the 300+ enrolled figure; and the US$2.9 billion in Africa CDC's Sep 24 G20+ readout stands. Checked grantdegraf@gmail.com for subject “[VitaAlert Brief]” over the last 48 hours: only the outbound Sep 26 and Sep 27 notifications were found, no team feedback to incorporate. The outbreak is now on Day 137 (PHEIC Day 135).

Superseded (Sep 27) — First reported de-escalation of the outbreak's footprint: DRC health ministry says seven health zones have passed 42 days and South Kivu is no longer among the currently affected provinces; no new national case count this run: An ABC News (Australia) feature published Sep 27 (Brianna Morris-Grant, reporting on the response in Bunia with UNICEF and Save the Children), quoting the latest daily report of DRC's Ministry of Public Health, Hygiene and Social Welfare, states that seven health zones have now passed the 42-day threshold without a new confirmed case and that “consequently, South Kivu is no longer among the currently affected provinces.” If borne out, that moves the currently-affected province count from seven to six — the first province to drop off this outbreak's active list since it was declared on May 15, and the first concrete, officially stated contraction of the geographic footprint after four months of expansion. CROSS-SOURCE CAVEAT, PRESERVED DELIBERATELY: ECDC's running page, last refreshed Sep 25 at 16:05, still counts seven provinces and 63 of 167 health zones and still lists South Kivu's cumulative 3 cases / 1 death in Miti-Murhesa. The two figures are not necessarily in conflict — a province can retain cumulative cases while ceasing to be currently affected — but they have not been reconciled in a single source, so this brief carries the de-escalation as a reported development under verification and leaves the headline footprint (7 provinces / 63 health zones) unchanged pending ECDC's Sep 28 epidemiological update or a WHO Disease Outbreak News. NO NEW NATIONAL CASE COUNT THIS RUN. ECDC still carries DRC data thru Sep 23 — 7,890 confirmed cases and 3,799 deaths, CFR ~48.2%, 893 hospitalized in isolation, 1,966 recovered — and WHO, CDC, Africa CDC and the Reuters/AP/AFP/Al Jazeera/UN News wires all still cite that same data cut, so the KPI case, death and tracing figures are unchanged. Note on the ABC figures: the piece cites cumulative totals of 7,672 cases / 3,699 deaths as of Sep 20 and Ituri at 5,406 as of Sep 10, both of which are behind the counts carried here and are not adopted. The same report re-states facts already carried in this brief: Ituri down about 26% and Haut-Uélé down about 15% over the last three weeks against a 73% rise in North Kivu; WHO AFRO regional emergency director Dr. Marie Roseline Belizaire assessing that this pattern shows the outbreak is “still not under control”; and case fatality among children under five above 60%. It adds operational texture rather than data: rumour and conspiracy narratives continue to shape community response in Ituri, treatment centres are running nurseries for children whose parents are hospitalized, and Save the Children's Ebola response lead Dr. Babou Rukengeza Makanda frames the effort as keeping essential health services running in volatile humanitarian conditions, in a response “of a scale the DRC has not experienced before”. All other status flags unchanged: no WHO PHEIC status change; no new countries with confirmed cases; no new American or international cases; no confirmed Kinshasa transmission beyond the single travel-linked case from May; Uganda's own 2026 outbreak remains formally closed (20 cases / 2 deaths, end declared Aug 25, last patient discharged Jul 16); the MSF-run BRAVO Ervebo research vaccination study continues with 3,700+ vaccinated of a ~20,000 frontline-worker target; no PARTNERS (MBP134/remdesivir) results beyond the 300+ enrolled figure; and the US$2.9 billion in Africa CDC's Sep 24 G20+ readout stands, with disbursement velocity still the operative metric. Checked grantdegraf@gmail.com for subject “[VitaAlert Brief]” over the last 48 hours: only the outbound Sep 26 notification was found, no team feedback to incorporate. The outbreak is now on Day 136 (PHEIC Day 134). (ABC News Australia, Sep 27, citing DRC Ministry of Public Health daily report; ECDC running page, Sep 25 16:05)
Superseded (Sep 26) — Case count rises to 7,890/3,799 (CFR ~48.2%, +117 cases / +40 deaths); contact-tracing follow-up slips to 83.4% for a second consecutive report; North Kivu matches Ituri on daily new cases for the first time: ECDC's running page refreshed Sep 25 at 16:05 — after holding at its Sep 23 refresh for a full day — carrying DRC's Sep 24 situation update with data thru Sep 23: 7,890 confirmed cases and 3,799 deaths, CFR ~48.2%, up 117 cases and 40 deaths on the 7,773/3,759 figure (data thru Sep 21) carried Sep 24–25. On Sep 23 alone: 70 new confirmed cases (Ituri 31, North Kivu 31, Haut-Uélé 6, Bas-Uélé 1, Tshopo 1) and 20 deaths. 893 patients are hospitalized in isolation (up from 839) and 1,966 have recovered (up from 1,935). (1) CONTACT TRACING IS THE WATCH ITEM. Follow-up on identified contacts has fallen to 83.4%, down from 84.5% in the Sep 21 data and 87.4% before that. That is a second consecutive decline, so this brief now reads it as a trend rather than a one-off fluctuation, and it compounds Africa CDC's standing caution that only an estimated 16% of the roughly 100,000 expected contacts have been identified at all — a falling follow-up rate on an already-thin denominator is the mechanism by which chains go undetected. (2) NORTH KIVU DRAWS LEVEL WITH ITURI. For the first time in this brief's record, North Kivu matched Ituri on daily new confirmed cases (31 each on Sep 23). This is consistent with the provincial divergence tracked here for two weeks — Ituri easing, North Kivu climbing — but it is the clearest single-day expression of it so far, and it means the national curve stays ambiguous even as Ituri's share of cumulative cases falls. Provincial detail (data thru Sep 23, via ECDC): Ituri 6,032 cases/2,764 deaths (28 of 36 health zones); North Kivu 1,480/884 (16 of 34); Haut-Uélé 322/130 (7 of 13); Tshopo 43/15 (7 of 23); Bas-Uélé 8/4 (3 of 11); South Kivu 3/1 (1 of 34); Sud-Ubangi 2/1 (1 of 16 — its second case). Geographic footprint unchanged at 63 of 167 health zones across the same seven provinces — no new province, no new health zone this run. (3) VACCINATION DETAIL. The Ervebo research vaccination programme under way in Ituri is the BRAVO study, run by Médecins Sans Frontières with Congolese health authorities, Africa CDC and other scientific partners. It plans to vaccinate roughly 20,000 frontline workers across Ituri and North Kivu — the two most affected provinces — and follow participants over time to assess whether Ervebo, licensed against Zaire ebolavirus rather than Bundibugyo, offers meaningful protection against BDBV. More than 3,700 people had been vaccinated as of the Sep 20 reports, drawn from the 20,000 doses allocated out of 70,000 made available to DRC authorities. This adds operational detail to, and does not change, the Sep 25 correction that the programme is already running rather than slipping to October–November. All other status flags unchanged: the US$2.9 billion in commitments confirmed in Africa CDC's Sep 24 G20+ readout stands, with disbursement velocity still the operative metric; no WHO PHEIC status change; no new countries with confirmed cases; no new American or international cases; no confirmed Kinshasa transmission beyond the single travel-linked case from May; Uganda's own 2026 outbreak remains formally closed (20 cases/2 deaths, WHO declared the end Aug 25); no PARTNERS (MBP134/remdesivir) results beyond the 300+ enrolled figure. ECDC published its week-39 Communicable disease threats report on Sep 25 and its next epidemiological update is due Sep 28. Checked grantdegraf@gmail.com for subject "[VitaAlert Brief]" over the last 48 hours: only the outbound Sep 24 and Sep 25 notifications were found, no team feedback to incorporate. The outbreak is now on Day 135 (PHEIC Day 133).
Superseded (Sep 25) — G20+ readout published: approximately US$2.9 billion mobilised, ~US$700 million of it at the Sep 23 New York meeting; Africa CDC demands dollar-level traceability; WHO's Ervebo research vaccination is already under way in Ituri, correcting the Oct–Nov start this brief carried: No newer official case count was published in the last 24 hours — DRC MOH figures remain 7,773 confirmed cases and 3,759 deaths (CFR ~48.4%, data thru Sep 21, DRC INSP SitRep n130 via ECDC), with 839 hospitalized in isolation, 1,935 recovered, 84.5% follow-up on identified contacts, and the footprint unchanged at 63 of 167 health zones across seven provinces. (1) G20+ READOUT. Africa CDC's post-meeting statement (New York/Addis Ababa, Sep 24) confirms that commitments since the outbreak was declared now total approximately US$2.9 billion — its itemised annex totals US$2.997bn — including roughly US$700 million announced in connection with the U.S.-convened G20+ Foreign Ministers' Meeting held Sep 23 on the margins of UNGA. Leading funders as of Sep 23 (USD m): United States 887, EU/European Commission 568, World Bank 433, Pandemic Fund 221, CEPI 196, Germany 127, African countries 110, United Kingdom 105, CERF 90, Gavi 45. This supersedes and corrects the unconfirmed pre-meeting figures this brief carried on Sep 23–24 (roughly $370m U.S. committed, a possible further $500m): the confirmed U.S. total is US$887m. Participants included DRC Prime Minister Judith Suminwa Tuluka, who called the outbreak a "major test" and an "absolute priority"; Uganda Foreign Minister Adonia Ayebare, who credited political leadership, a prepared health system, community trust and cross-border cooperation for ending Uganda's outbreak; U.S. Under Secretary of State Allison Hooker; EU Commissioner Hadja Lahbib (EU total mobilisation €500m); and World Bank Vice President Mamta Murthi. Africa CDC Director-General Dr. Jean Kaseya struck the cautionary note: "pledges alone will not stop Ebola. We must be able to trace every single dollar — from commitment to disbursement, from implementing partner to expenditure, and ultimately to the services delivered." Africa CDC will strengthen its Financial Tracking Mechanism to give the DRC government a consolidated view of commitments, disbursements, implementation locations and results. The operative metric from here is disbursement velocity, not pledge size — this brief will track the gap between the US$2.9bn committed and what actually reaches health zones. (2) ERVEBO CORRECTION. WHO announced Sep 21 (WHO AFRO, via UN News) that the Ervebo research vaccination programme is now under way in Ituri province, with 20,000 doses allocated to it from the 70,000 made available to DRC authorities. This supersedes the "slipping toward an October–November start" line carried in this brief since Sep 21. The WHO-backed vaccine advisory panel recommended earlier in September that Ervebo — licensed against Zaire ebolavirus, not Bundibugyo — be used for research purposes only at this stage, with its unknown efficacy against BDBV clearly communicated; limited data and anecdotal reports suggest possible partial protection. The frontline compassionate-use campaign continues in parallel across Tshopo, Bas-Uele and Haut-Uele. (3) PAEDIATRIC BURDEN. WHO AFRO data published Sep 21 quantifies what this brief has tracked since August: children are nearly a quarter of confirmed cases but almost a third of deaths, and case fatality among under-fives exceeds 60% versus under 30% for adults — driven, per WHO's Dr. Daniel Youkee and ALIMA's Dr. Chaka Keita, by shortages of paediatric-sized equipment and trained staff. Children are eligible, with parental consent, for the PARTNERS treatment trial. All other status flags unchanged: no WHO PHEIC status change, no new countries with confirmed cases, no new American or international cases, Uganda's outbreak formally closed (20 cases/2 deaths), no confirmed Kinshasa transmission beyond the single travel-linked case from May, no PARTNERS results beyond the 300+ enrolled figure. Checked grantdegraf@gmail.com for subject "[VitaAlert Brief]" in the last 48 hours: only the outbound Sep 23 and Sep 24 notifications were found, no team feedback to incorporate. The outbreak is now on Day 134 (PHEIC Day 132).
Superseded (Sep 24) — Case count rises to 7,773/3,759 (CFR ~48.4%); G20 Foreign Ministers' Meeting on Ebola takes place in New York with no outcomes yet published; ECDC deploys its own experts to DRC: DRC Ministry of Health data thru Sep 21 (DRC INSP SitRep n130, published Sep 22, reflected in ECDC's Sep 23 update) puts the outbreak at 7,773 confirmed cases and 3,759 deaths — CFR ~48.4% — up 101 cases and 60 deaths versus the 7,672/3,699 figure (data thru Sep 19) carried since Sep 23. On Sep 21 alone: 40 new confirmed cases (Ituri 19, North Kivu 13, Haut-Uélé 5, Tshopo 3) and 27 deaths. 839 patients remain hospitalized in isolation (down from 886), and 1,935 have recovered. Contact-tracing follow-up on identified contacts eased to 84.5%, down from 87.4% — this brief will watch whether that is the start of a trend or a one-off fluctuation. Geographic footprint is unchanged at 63 of 167 health zones across the same seven provinces — no new province, no new health zone this run. Provincial detail (data thru Sep 21, via ECDC): Ituri 5,966 cases/2,737 deaths (28 of 36 health zones); North Kivu 1,438/872 (16 of 34 health zones), continuing its climb; Haut-Uélé 316/129 (7 of 13); Tshopo 42/15 (7 of 23); Bas-Uélé 7/4 (3 of 11); South Kivu 3/1 (1 of 34); Sud-Ubangi 1/1 (1 of 16). SEPARATELY: the U.S.-convened G20 Foreign Ministers' Meeting on Accelerating Collective Action to Defeat Ebola took place as scheduled on Sep 23 in New York, on the margins of the UN General Assembly; Africa CDC Director-General Dr. Jean Kaseya represented the African Union's 55 member states, with DRC and Uganda authorities also participating. No confirmed meeting outcomes, funding commitments, or formal readout had been published as of this run — preliminary coverage ahead of the meeting referenced the roughly $370 million the U.S. has committed to the response to date and discussion of a possible further $500 million commitment, but neither is confirmed as an actual outcome; this brief will follow up once a readout is published. ALSO NEW: ECDC announced Sep 21 that it has deployed its own experts to DRC to increase technical support for the response — a step beyond ECDC's standing remote epidemiological monitoring role. All other status flags unchanged: no WHO PHEIC status change, no confirmed South Sudan/CAR/other new-country cases, no new American or international cases, Uganda's own 2026 outbreak remains formally closed (20 cases/2 deaths), no confirmed Kinshasa transmission beyond the single travel-linked case from May, no PARTNERS (MBP134/remdesivir) trial results beyond the 300+ enrolled figure already carried.

Superseded (Sep 23) — Case count rises to 7,672/3,699 (CFR ~48.2%); G20 Foreign Ministers' Meeting on Ebola convened in New York: DRC Ministry of Health data thru Sep 19 (published via Outbreak News Today/Robert Herriman, Sep 20) puts the outbreak at 7,672 confirmed cases and 3,699 deaths — CFR ~48.2% — up 58 cases and 23 deaths versus the 7,614/3,676 figure (data thru Sep 18) carried since Sep 21. On Sep 19 alone: 58 new confirmed cases (Ituri 38, North Kivu 14, Haut-Uele 5, Tshopo 1), and 23 deaths, including 13 community deaths. 886 patients remain hospitalized in isolation. Geographic footprint is unchanged at 63 of 167 health zones across the same seven provinces — no new province, no new health zone this run. SEPARATELY: the U.S. convened a G20 Foreign Ministers' Meeting on Accelerating Collective Action to Defeat Ebola today, Sep 23, in New York, on the margins of the UN General Assembly. Africa CDC Director-General Dr. Jean Kaseya represented the African Union's 55 member states, with authorities from both DRC and Uganda participating; per its Sep 20 statement welcoming the meeting, Africa CDC called on partners to turn solidarity into "faster, transparent and accountable delivery." No meeting outcomes or funding commitments had been published as of this run — this brief will follow up. All other status flags unchanged: no WHO PHEIC status change, no confirmed South Sudan/CAR/other new-country cases, no new American or international cases, Uganda's own 2026 outbreak remains formally closed (20 cases/2 deaths), no confirmed Kinshasa transmission beyond the single travel-linked case from May, no PARTNERS (MBP134/remdesivir) trial results beyond the 300+ enrolled figure already carried.

Superseded (Sep 21) — Case count rises to 7,614/3,676 (CFR ~48.3%); a new health zone, Dungu (Haut-Uele), affected for the first time, bordering South Sudan; WHO's Phase 3 vaccine trial timeline appears to be slipping: DRC Ministry of Health data thru Sep 18 (published via Outbreak News Today/Robert Herriman, Sep 20) puts the outbreak at 7,614 confirmed cases and 3,676 deaths — CFR ~48.3% — up 139 cases and 71 deaths versus the 7,475/3,605 figure (data thru Sep 16) carried since Sep 20. On Sep 18 alone: 73 new confirmed cases (Ituri 46, North Kivu 18, Haut-Uele 6, Tshopo 3), 37 deaths (12 within Ebola Treatment Centres — 10 Ituri, 2 North Kivu — plus 25 community deaths), and 41 new recoveries (30 Ituri, 6 Haut-Uele, 3 North Kivu, 2 Tshopo). NEW HEALTH ZONE: Dungu, in Haut-Uele province, was affected for the first time on Sep 18 — notable because it borders South Sudan, prompting Outbreak News Today to flag the need for strengthened cross-border surveillance; South Sudan remains a WHO-designated high-risk country for importation (porous borders, weak health system, high population mobility, humanitarian needs) but has not detected any cases to date. Geographic footprint is now 63 of 167 health zones (37.7%) across the same seven provinces — up from 62. Ituri remains the epicenter, accounting for 77.2% of cumulative cases across the seven provinces and 63.0% of the latest new confirmed cases, consistent with the geographic split (Ituri easing, North Kivu rising) described in the Africa CDC ECG's Sep 17 review already carried in this brief. SEPARATELY: WHO's Phase 3 Ervebo vaccine trial, described since Sep 18 as expected "in the next couple of weeks," now appears to be slipping toward an October–November start, per earlier WHO statements reflected in Healio and STAT News reporting — a walk-back from the firmer near-term timeline previously carried in this brief; no confirmed trial-start date exists either way as of today, and this brief will continue tracking it. All other status flags unchanged: no WHO PHEIC status change, no confirmed South Sudan/CAR/other new-country cases (despite Dungu's proximity), no new American or international cases, Uganda's own 2026 outbreak remains formally closed (20 cases/2 deaths), no confirmed Kinshasa transmission, no PARTNERS (MBP134/remdesivir) trial results beyond the 300+ enrolled figure already carried.

Superseded (Sep 20) — Case count advances for the first time since Sep 15, to 7,475/3,605 (CFR ~48.2%); no change to outbreak status beyond the Sep 17 Africa CDC ECG review already carried in this brief: The DRC Ministry of Health's data thru Sep 16, published within Africa CDC's Sep 17 briefing, puts the outbreak at 7,475 confirmed cases and 3,605 deaths — up 71 cases and 32 deaths from the Sep 15 count (7,404/3,577) already reflected in yesterday's brief, with the case-fatality ratio essentially flat at ~48.2%. The new cases were distributed across Ituri (41), North Kivu (27), Haut-Uele (2) and Tshopo (1) — no new provinces, still 7 confirmed. Ituri remains the epicenter with 5,792 cumulative cases (2,642 deaths) across 28 of 36 health zones; North Kivu, the outbreak's most active hotspot, has climbed to 1,350 cases (828 deaths) across 16 of 34 health zones — consistent with the Africa CDC Emergency Consultative Group's (ECG) Sep 17 finding that the situation remains heterogeneous, with increases concentrated in North Kivu even as Ituri shows encouraging declines. That ECG review — chaired by Prof. Salim Abdool Karim and reported in yesterday's brief — is unchanged: its position remains "cautious optimism," the data do not yet confirm the outbreak has reached its peak, and it recommends maintaining Africa CDC's continental PHECS designation and scaling up response intensity, especially in North Kivu. All other status flags unchanged: no WHO PHEIC status change, no confirmed South Sudan/CAR/other new-country cases, no new American or international cases, Uganda's own 2026 outbreak remains formally closed (20 cases/2 deaths), no confirmed Kinshasa transmission, no PARTNERS trial results beyond the 300+ enrolled figure already carried.

The outbreak is now on Day 129 (PHEIC Day 127).
Superseded (Sep 19) — Africa CDC's independent scientific review backs "cautious optimism" but says the data do not yet confirm the outbreak has peaked; recommends maintaining the continental emergency designation: No newer official case count was found that day — the DRC Ministry of Health's data thru Sep 15 (7,404 cases/3,577 deaths, CFR ~48.3%) remained the latest official figure, unchanged since Sep 18. The substantive development is the completion of an independent scientific review by the Africa CDC Emergency Consultative Group (ECG) — a 20-member body of senior African scientists and public health experts chaired by Prof. Salim Abdool Karim — published Sep 17 from Addis Ababa, four months after Africa CDC designated the outbreak a Public Health Emergency of Continental Security (PHECS), its own continental-level designation distinct from WHO's PHEIC. The ECG's position: "cautious optimism." Declines in cases and deaths in some hotspots, including Ituri, are encouraging, but the situation remains heterogeneous, with increases in some health zones, particularly North Kivu, and the available data do not yet confirm that the outbreak has reached its peak or that transmission has been sustainably interrupted — directly corroborating, not superseding, WHO Director-General Tedros's Sep 16 "far from over" framing already carried in this brief. The ECG recommended: maintaining the PHECS designation and continental coordination while monitoring defined de-escalation criteria; scaling up response intensity, especially in North Kivu, and avoiding premature relaxation of interventions; urgently addressing persistent community deaths, which remain around 60% of reported deaths; strengthening community ownership and accountability beyond awareness activities; strengthening contact identification, tracing and data quality — cautioning that high percentages of contacts traced can mask gaps in the initial identification and completeness of contact lists, a distinction consistent with this brief's standing 87.4%-follow-up-vs-~16%-actual-tracing-rate framing; protecting and restoring essential health services disrupted by the outbreak; and continuing observational vaccine studies with clear informed consent on the uncertainty of protection against Bundibugyo virus. Karim: "The evidence gives us grounds for cautious optimism, but it does not yet show consistent control across all affected areas... Sustained interruption of transmission has to be demonstrated before de-escalation is considered." Africa CDC Director-General Dr. Jean Kaseya said the agency would act on the ECG's recommendations. This is the first independent scientific-body review of the outbreak's trajectory published to date. All other status flags unchanged: no WHO PHEIC status change (no third IHR Emergency Committee meeting found), no confirmed South Sudan/CAR/other new-country cases, no new American or international cases, Uganda's own 2026 outbreak remains formally closed (20 cases/2 deaths), no confirmed Kinshasa transmission, no update on the Savo displacement-site cluster (Djugu, Ituri) beyond the 3 cases already reported Sep 13, no PARTNERS trial results beyond the 300+ enrolled figure already carried.

The outbreak is now on Day 128 (PHEIC Day 126).
Superseded (Sep 18) — Case count rises to 7,404/3,577 (CFR ~48.3%); WHO's Tedros gives fuller detail on Ituri's still-dominant share of new cases and a firmer vaccine-trial timeline: The DRC Ministry of Health's Sep 15 situation report (published via Outbreak News Today/Robert Herriman, Sep 17) puts the outbreak at 7,404 confirmed cases and 3,577 deaths — CFR ~48.3% — with 930 patients in isolation (up from 905) and 1,776 recovered (+50); that is +146 cases and +67 deaths versus the 7,258/3,510 figure (data thru Sep 13) carried since Sep 16. New cases in the latest 24-hour window (Sep 15-16) broke down as Ituri +35, North Kivu +21, Bas-Uélé +2, Tshopo +1. Contact-tracing follow-up is now cited at 87.4% (down marginally from 88%, consistent with growth in the contact pool rather than a tracing slowdown). Geographic footprint is unchanged at 62 of 167 health zones across the same seven provinces; Ituri's cumulative count is now 5,751 cases/2,622 deaths across 28 of 36 health zones — still 77.7% of the national total. SEPARATELY, WHO published the full transcript of Director-General Tedros Adhanom Ghebreyesus's Sep 16 Geneva press briefing, giving fuller detail than the wire-service summary already reflected in this brief since Sep 17: Tedros said WHO is "starting to see encouraging signs that we are gaining ground" — transmission is declining in the most-affected parts of Ituri, South Kivu has had no new cases since May, and the epidemic "has been contained mostly in northeastern DRC," with Uganda's own outbreak "swiftly stopped." But he stressed the Ituri reduction is "from a high level": in the past week alone Ituri reported roughly 300 new cases and 160 deaths — nearly half the national total — while North Kivu's weekly case count has "almost doubled" to more than 200 over the past two weeks, underpinning his line that "it is many outbreaks, in many places." STAT News (Helen Branswell, Sep 16) headlined WHO's framing as "cautious optimism" — treated here as complementary to, not a reversal of, the "far from over" framing carried since Sep 17, since both trace to the same briefing. WHO also gave a firmer vaccine-trial timeline than the "coming weeks" estimate previously carried: per Meg Doherty (WHO director of science for health, via STAT), a Phase 3 randomized trial of candidate Ebola vaccines is expected to begin "in the next couple of weeks," starting with Ervebo (licensed against Zaire ebolavirus, with some evidence of cross-protection against Bundibugyo), with Bundibugyo-specific candidates added once they clear Phase 1 safety/dosing; separately, a DRC/MSF observational trial offering frontline workers in hotspots a shot of Ervebo followed a month later by an experimental Sudan-strain vaccine is due to start "later this week or early next week," comparing outcomes between vaccinated and unvaccinated cohorts. ALSO UPDATED: WHO's Sep 10 Disease Outbreak News (DON617), not fully reflected in this brief's PARTNERS-trial line until now, shows the PARTNERS platform trial (MBP134/remdesivir) has enrolled more than 300 confirmed cases (up from 250+) across five clinical management facilities in Ituri (up from three); target remains 700-1,000, no preliminary results released. All other status flags unchanged: no PHEIC status change (no third Emergency Committee meeting found), no confirmed South Sudan/CAR/other new-country cases, no new American or international cases, Uganda's own 2026 outbreak remains formally closed (20 cases/2 deaths), no confirmed Kinshasa transmission, no update on the Savo displacement-site cluster (Djugu, Ituri) beyond the 3 cases already reported Sep 13. Checked grantdegraf@gmail.com for subject "[VitaAlert Brief]" in the last 48 hours: only the outbound Sep 16 and Sep 17 notifications themselves were found, no team reply/feedback to incorporate. The outbreak is now on Day 127 (PHEIC Day 125).
Superseded (Sep 17) — WHO Director-General Tedros pushes back on DRC government's "peak passed" narrative; North Kivu weekly cases have doubled: No newer official case count was found today — the DRC epidemiological report data thru Sep 13 (7,258 cases/3,510 deaths, CFR ~48.4%) remains the latest official figure, unchanged since Sep 16. The substantive development is an on-record statement from WHO Director-General Tedros Adhanom Ghebreyesus at an online press conference Sep 16 (Al Jazeera/AFP/AP/Reuters): despite "encouraging signs," he said the fight in eastern DRC is "far from over," with weekly case counts in North Kivu having doubled over the past two weeks — from roughly 100 to more than 200 — and that "the area is so vast that it's hard to speak of a single epidemic," describing "many outbreaks in many places." Tedros confirmed transmission is declining in Ituri, the epicenter, and that South Kivu has recorded no new cases since May — consistent with content already in this brief — but stated plainly: "make no mistake, the epidemic continues to grow and continues to kill." This is the first direct, attributed WHO leadership comment responding to DRC Communication Minister Patrick Muyaya's "peak reached in the third week of August" characterization carried in this brief since Sep 13, and it complicates rather than confirms that narrative — this brief now treats the trajectory as contested between the DRC government's declining-trend framing and WHO's growing-epidemic framing, pending the next WHO Disease Outbreak News update. Tedros cited the same rounded case/death totals already in this brief (>7,200 cases, >3,500 deaths, seven provinces). SEPARATELY, WHO's director of science, research, evidence and quality for health, Meg Doherty, said treatment trials (the PARTNERS platform trial of MBP134 and remdesivir) and post-exposure prophylaxis development are "picking up speed," with no results reported yet, and disclosed that more than 3,000 healthcare and frontline workers have now been vaccinated with Ervebo under compassionate use — a specific figure new to this brief, refining the general "campaign under way" language carried since late August; the standing caveat is unchanged (Ervebo is licensed against Zaire ebolavirus, and its effectiveness against Bundibugyo is not known). All other status flags unchanged: no PHEIC status change (no third Emergency Committee meeting found), no PARTNERS trial results, no confirmed South Sudan/CAR/other new-country cases, no new American or international cases, Uganda's own 2026 outbreak remains formally closed (20 cases/2 deaths), no confirmed Kinshasa transmission, no update on the Savo displacement-site cluster (Djugu, Ituri) beyond the 3 cases already reported Sep 13. The outbreak is now on Day 126 (PHEIC Day 124).
Superseded (Sep 16) — Case count rises to 7,258/3,510 (CFR ~48.4%); DRC Communication Minister names a specific "peak" date and slowing hotspots: DRC's epidemiological report published Sep 14 (data thru Sep 13, via ECDC's Sep 14 page update and Outbreak News Today/Robert Herriman) puts the outbreak at 7,258 confirmed cases and 3,510 deaths — CFR ~48.4% — with 905 patients in isolation or treatment (down slightly from 923) and 1,726 recovered (+14); that is +58 cases and +35 deaths versus the 7,200/3,475 figure (data thru Sep 12) carried since Sep 15, with the new cases breaking down as Ituri +44, North Kivu +12, Haut-Uele +2. Overall contact-tracing follow-up remains at 88%, unchanged. Ituri's cumulative count is now 5,659 cases/2,583 deaths across 28 of 36 health zones. Geographic footprint is unchanged at 62 of 167 health zones across the same seven provinces (Ituri, North Kivu, South Kivu, Haut-Uele, Bas-Uele, Tshopo, Sud-Ubangi/Bulu). NOTABLE DEVELOPMENT: CIDRAP (Sep 15, citing DRC Minister of Communication Patrick Muyaya's Sep 13 post on X) reports Muyaya stated directly that "the peak has been reached since the beginning of the third week of the month of August," adding that 10 of 61 health zones have recorded no case in at least 21 days and that the main hotspots — Nia Nia, Nizi and Mongbwalu — are showing a continuous slowdown in transmission. This is the same government "peak passed in late August" narrative already carried in this brief since Sep 13/15, now corroborated with a direct, attributed ministerial quote and specific health-zone detail rather than a new development in itself — this brief continues to treat it as a DRC government characterization pending independent confirmation by a WHO Disease Outbreak News update, given the outbreak's repeated pattern of re-acceleration in new health zones (North Kivu, Sud-Ubangi). Note: Muyaya's post cites "61" health zones against ECDC/WHO's most recently published count of 62 of 167 — a minor, unexplained cross-source discrepancy, not incorporated as a footprint change. CIDRAP also reiterates the outbreak "remains the second-largest Ebola outbreak in history" by case count. All other status flags unchanged: no PHEIC status change (no third Emergency Committee meeting found), no PARTNERS (MBP134/remdesivir) trial results, no confirmed South Sudan/CAR/other new-country cases, no new American or international cases, Uganda's own 2026 outbreak remains formally closed (20 cases/2 deaths), no confirmed Kinshasa transmission, and no update on the Savo displacement-site cluster (Djugu, Ituri) beyond the 3 cases already reported Sep 13. No team feedback emails were found in Grant's inbox in the lookback window. The outbreak is now on Day 125 (PHEIC Day 123).
Superseded (Sep 15) — Case count rises to 7,200/3,475 (CFR ~48.3%); DRC report cites epidemic peak passed in late August with a gradual decline since; new cases at a 70,000-person Ituri displacement site: DRC's epidemiological report published Sunday, Sep 13 (data thru Sep 12, via Outbreak News Today/Robert Herriman) puts the outbreak at 7,200 confirmed cases and 3,475 deaths — CFR ~48.3% — with 923 patients in isolation or treatment and 1,712 recovered (+101 since the prior count); that is +178 cases and +77 deaths versus the 7,022/3,398 figure (data thru Sep 10) carried since Sep 13. Overall contact-tracing follow-up is now cited at 88%, up from 86.3%. Geographic footprint is unchanged at 62 of 167 health zones across the same seven provinces (Ituri, North Kivu, South Kivu — only Miti-Murhesa — Haut-Uele, Bas-Uele, Tshopo and Sud-Ubangi/Bulu). MOST SIGNIFICANT DEVELOPMENT: the same DRC report states the epidemic's peak was reached during the third week of August 2026, with a gradual decline in confirmed cases and deaths since — the first official trajectory signal pointing toward deceleration since the outbreak began. This brief treats it as a DRC government characterization pending independent confirmation by a WHO Disease Outbreak News update, and notes it should be read alongside the still-shifting balance between provinces (Ituri declining, North Kivu/Haut-Uele previously reported rising). It is loosely echoed by DRC response-team comments to Radio Okapi (Sep 11) describing the epidemic as "sous contrôle" ("under control") — a self-assessment by the response coordination team, presented here as a claim rather than an independently verified fact. Operational developments: Radio Okapi (Sep 13) reports three confirmed cases at the Savo displacement site in Djugu territory, Ituri — a site housing more than 70,000 internally displaced people in crowded conditions with limited handwashing and sanitation access; the patients were transferred to Fataki hospital, where infection was confirmed, and contact tracing has begun at the site, which this brief flags as a location warranting close monitoring given its density. Separately, Uganda has imposed a 21-day quarantine on students arriving from DRC (Radio Okapi, Sep 13), a new cross-border precaution distinct from Uganda's own closed outbreak, and Radio Okapi (Sep 14) reports community deaths continue to complicate the response in Bule, Ituri, consistent with the outside-ETU mortality gap flagged in CDC's MMWR scorecard. All other status flags unchanged: no PHEIC status change (no third Emergency Committee meeting found), no PARTNERS (MBP134/remdesivir) trial results, no confirmed South Sudan/CAR/other new-country cases, no new American or international cases, Uganda's own 2026 outbreak remains formally closed (20 cases/2 deaths), no confirmed Kinshasa transmission. No team feedback emails were found in Grant's inbox in the lookback window. The outbreak is now on Day 124 (PHEIC Day 122).
Superseded (Sep 13) — Outbreak passes 7,000 confirmed cases; Sud-Ubangi formally added as the 7th affected province: DRC Ministry of Health figures reported Sep 12 (data thru Sep 10, via AFP/Al Jazeera and Outbreak News Today) put the outbreak at 7,022 confirmed cases and 3,398 deaths — CFR ~48.4% — with 837 patients in isolation or treatment. That is +80 cases and +49 deaths (31 community + 18 in Ebola Treatment Centres) since the Sep 9 figure (6,942/3,349), with 24 additional recoveries. Daily breakdown for Sep 10: Ituri +30, North Kivu +43, Haut-Uele +6, Sud-Ubangi +1 (a death). Sud-Ubangi's Bulu health zone has now been formally added to DRC's official affected-province list — resolving yesterday's caveat — bringing the total to seven provinces and 62 of 167 health zones; this is the same travel-linked patient reported Sep 11, and no further Sud-Ubangi cases or confirmed local transmission have been reported. Al Jazeera separately reports Ebola detected among schoolchildren in Bunia, Ituri, as the new term begins, prompting mandatory handwashing and reduced class sizes — an operational concern, not evidence of a new cluster. Cases/deaths continue to decline in Ituri (the epicenter) while rising sharply in North Kivu and Haut-Uele. Separately, a multi-vaccine efficacy trial (Ervebo prioritized) has reportedly slipped to an October–November start, later than earlier mid-September expectations; frontline/compassionate-use vaccination continues. All other status flags unchanged: no PHEIC status change, no PARTNERS (MBP134/remdesivir) trial results, no confirmed South Sudan/CAR cases, no new American/international cases, Uganda's outbreak remains closed, no confirmed Kinshasa transmission. The outbreak is now on Day 122 (PHEIC Day 120).
Superseded (Sep 12) — Ebola reaches a seventh DRC province, Sud-Ubangi, after a patient's cross-border odyssey through Rwanda and Uganda; case count rises to 6,942/3,349 (CFR ~48.2%): The acting governor of the northwestern province of Sud-Ubangi, Jean-Rene Galekwa Vundawe, announced Friday (Sep 11) that DRC's National Institute for Biomedical Research (INRB) confirmed Bundibugyo virus in a sample from the Bulu health district; INRB director Jean-Jacques Muyembe confirmed the positive result (Al Jazeera/AFP/AP/Reuters, Sep 11). The patient — a 23-year-old man — travelled from South Kivu through Rwanda and Uganda into Ituri, developed symptoms in Kisangani (Tshopo), then continued by boat down the Congo River before dying in Gwaka, Sud-Ubangi. Sud-Ubangi borders the Central African Republic and the Republic of the Congo, marking the outbreak's first reach into DRC's west. Galekwa said the patient's and the boat's route "exposes the populations" of North-Ubangi, Tshopo and Mongala provinces, and that 38 contacts have been identified and quarantined. Caveat: local transmission is not yet confirmed in Sud-Ubangi and it has not been added to the official affected-province list (still six); no transmission has been linked to this patient in Rwanda or Uganda. Case count: DRC government figures reported Sep 9 (Wednesday) put the outbreak at 6,942 confirmed cases and 3,349 deaths — CFR ~48.2% — up 185 cases/82 deaths since the Sep 7 WHO DON617 figure (6,757/3,267). WHO says the outbreak "remains out of control" and is on track to surpass the 2014-2016 West Africa epidemic. Al Jazeera separately reports cases/deaths declining in Ituri (the epicenter) but rising sharply in North Kivu and Haut-Uele. All other status flags unchanged: no PHEIC status change, no PARTNERS trial results, no confirmed South Sudan/CAR cases, no new American/international cases, Uganda's outbreak remains closed, no confirmed Kinshasa transmission (though the river route bears watching). CDC's Sep 1 MMWR scorecard was formally published in the Sep 10 print issue with no new data. The outbreak is now on Day 121 (PHEIC Day 119).
Superseded (Sep 2) — Death toll reaches 2,950, within 50 of 3,000; case count 6,100; contact follow-up climbs to 86.3%: DRC reported on August 31 (data through August 30) a total of 6,100 confirmed cases and 2,950 deaths — CFR ~48.4% — with 814 patients hospitalized in isolation and 1,383 recovered (source: DRC INSP situation report 108 via ECDC, page last updated Sep 1 at 17:00). That is +59 cases and +39 deaths in 24 hours. The new cases came from Ituri (44), North Kivu (8), Haut-Uele (6) and Bas-Uele (1) — Bas-Uele's first new confirmed case in over a week, taking that province from 3 to 4 cases. Contact follow-up has risen again to 86.3% of identified case contacts, up from 84.4%; the standing caveat is unchanged, since this measures follow-up on contacts already registered, not the far lower share of expected contacts ever identified. Hospitalized-in-isolation numbers fell from 896 to 814, which on its own is ambiguous — it can reflect discharges and deaths as readily as reduced incidence. Note also that the two data series this brief has tracked separately have now reconciled: ECDC's Aug 30 report figure is 6,041/2,911, identical to the DRC Ministry of Communication national figure carried in yesterday's brief, confirming that was INSP data through Aug 29 rather than a divergent count. Provincial breakdown (data thru Aug 30): Ituri 5,016 cases/2,274 deaths across 28 of 36 health zones; North Kivu 836/566 across 15 of 34 (provincial CFR 67.7%, still the highest of any province and still under investigation); Haut-Uele 222/97 across 6 of 13; Tshopo 19/9 across 7 of 23; Bas-Uele 4/3 across 3 of 11; South Kivu 3/1 across 1 of 34. Geographic footprint unchanged at six provinces and 60 of 151 health zones.
Superseded (Sep 2) — US CDC publishes its first operational scorecard for this outbreak, and nearly every indicator is failing: CDC released an MMWR early-release Notes from the Field on September 1 (Kabasele et al., DOI 10.15585/mmwr.mm7535e1) giving the first published, target-by-target assessment of the DRC response. Measured over the three-week window July 31 – August 21: an average of 10.6 contacts identified per confirmed case against a target of ≥20, which CDC reads as direct evidence of underascertainment; contact-tracing completeness 82% against a >95% target; 72% of validated alerts received laboratory testing against >90%, meaning a substantial share of suspected cases are never tested; 24% test positivity against a 0% target; 59% of confirmed Ebola deaths occurring outside an Ebola treatment unit against a 0% target; and only 49% of affected health zones have even one safe-and-dignified-burial team against a 100% target. National ETU bed occupancy at 64% is the one indicator meeting its target (<80%), but CDC notes individual health zones running as high as 140%. Two further indicators are stale rather than met: 83% of alerts investigated within 24 hours (last reported Aug 5, target >90%) and 15–20% of new cases previously identified as known contacts (last reported Jul 12, target >90%) — the latter confirming most cases are still occurring outside known transmission chains. CDC's own conclusion is unambiguous: these gaps, together with continued geographic expansion, "indicate uncontrolled expansion of the outbreak." This is the most rigorous independent audit of response performance published to date, and it corroborates in structured form what Africa CDC has said informally since mid-August.
Superseded (Sep 1) — The outbreak crosses 6,000 confirmed cases: 6,041 cases and 2,911 deaths, CFR ~48.2%: DRC's Ministry of Communication and Media released updated national figures on August 31 putting the epidemic at 6,041 confirmed cases and 2,911 deaths, with 1,366 recovered — reported by AFP and carried by Al Jazeera, Africanews and Medical Xpress. That is +247 cases and +125 deaths against the 5,794/2,786 figure carried since Aug 29 — the multi-day catch-up increment this brief anticipated after the weekend reporting gap — and puts the death toll within 89 of 3,000. UN Secretary-General António Guterres has called it "the fastest-spreading Ebola epidemic ever recorded." Separately, ECDC's epidemiological update published August 31 after a three-day stall, carrying DRC's Aug 29 situation update (data through August 28) at 5,945 cases and 2,862 deaths, 896 hospitalised in isolation and 1,327 recovered — and one genuinely encouraging movement: contact follow-up has risen to 84.4% of identified case contacts, from 82.3%. The caveat stands — that measures follow-up on contacts already registered, not the ~16% of expected contacts ever identified. Provincial detail (data thru Aug 28): Ituri 4,911/2,212 (28 of 36 health zones), North Kivu 800/546 (15 of 34, provincial CFR 68.25%, the highest anywhere in this outbreak and still under investigation), Haut-Uele 209/93 (6 of 13, up sharply from 139 cases on Aug 18 and now the third-largest provincial burden), Tshopo 19/8 (7 of 23), Bas-Uele 3/2 (3 of 11), South Kivu 3/1 (1 of 34). The geographic footprint is unchanged: still six provinces and 60 of 151 health zones.
Superseded (Aug 29) — Case count rises to 5,794/2,786 (CFR ~48.1%); affected health zones widen to 60 of 151 within the same six provinces: DRC published a situation update on August 27 (data through August 26) reporting 5,794 confirmed cases and 2,786 deaths — CFR ~48.1% — up +81 cases and +42 deaths from the 5,713/2,744 figure (data thru Aug 25) used in yesterday's brief. 843 patients are hospitalized in isolation, and 82.3% of identified case contacts are under follow-up across the affected provinces — still well short of the 95% operational target, and a figure that measures only contacts already on a list, not the far larger population of contacts never identified (Africa CDC's separate estimate puts actual tracing at ~16% of expected contacts). The one structural movement in today's data: 60 of 151 health zones are now affected, up from the 56 of 151 this brief has carried since Aug 21. That is a four-zone widening of the outbreak's geographic footprint within the existing six provinces — not spread into a seventh province, and not by itself evidence of accelerating transmission, but it is the metric most directly tracking how much territory the response has to cover. ECDC cautions that DRC's confirmed-case and death figures remain "under continuous review and harmonisation"; its next epidemiological update publishes August 31. The ERVEBO frontline-worker vaccination campaign launched Aug 27 in Kisangani continues, primarily implemented across Tshopo, Bas-Uele and Haut-Uele, with the unchanged caveat that Ervebo is licensed against Zaire ebolavirus, not Bundibugyo, and is deployed here under compassionate use with human efficacy against BDBV still unproven. Uganda's outbreak remains formally closed — WHO declared it over Aug 26 after the 42-day countdown; final toll 20 confirmed cases and 2 deaths, last case Jun 21, last patient discharged Jul 16. No new provinces (still six), no confirmed South Sudan/CAR/other new-country cases, no new American or international cases, no confirmed Kinshasa transmission, no PHEIC status change, and no PARTNERS trial results yet — the MBP134/remdesivir platform trial continues enrolling toward its 1,000-patient, four-arm target. The outbreak is now on Day 107 (PHEIC Day 105). Verification note: an aggregated search result encountered during this run asserted "one confirmed case in Kinshasa" attributed to WHO around May 17. That claim could not be corroborated in ECDC's authoritative running update — which lists six affected provinces and does not include Kinshasa — and it directly contradicts DRC Health Minister Kamba's on-record Aug 21 statement that no cases have been confirmed in the capital. It has not been incorporated; this brief continues to report no confirmed Kinshasa transmission. (DRC INSP situation update, Aug 27, via ECDC — page last updated Aug 28; ECDC/WHO AFRO — Uganda closure)
Superseded (Aug 28) — DRC administers its first Ebola vaccine doses of the outbreak; campaign launches in Kisangani; case count rises to 5,713/2,744: Congo began vaccinating against Ebola on Thursday, August 27 — the first doses actually administered in this outbreak, more than three months after it was declared. The campaign was officially launched in Kisangani, capital of Tshopo province, by Health Minister Roger Kamba, with health workers and other frontline responders prioritized alongside people who have been in contact with patients. Kamba: "We have decided to use the Ervebo vaccine to protect first those who are on the front line, therefore our health care providers, but also people who have been in contact with patients." The campaign is expected to cover 14 health zones across Tshopo, Bas-Uele and Haut-Uele, and DRC's state news agency reports more than 50,000 Ervebo doses received — up from the ~16,250-dose first tranche that landed at N'Djili on Aug 21 — out of the 70,000 approved by the ICG on Aug 20 (50,000 for frontline/health workers, 20,000 reserved for the Phase 3 cross-protection trial). Important caveat: Ervebo is licensed against Zaire ebolavirus, not Bundibugyo, and is being deployed here under a compassionate-use program; whether it prevents Bundibugyo illness in humans is still unproven, with only animal and lab data suggesting possible partial cross-protection. Africa CDC's Placide Mbala Kingebeni (director for research, clinical trials and innovation) said data will be collected during the campaign to measure how well the vaccine performs. On the numbers, DRC's count has advanced to 5,713 confirmed cases and 2,744 deaths (data thru Aug 25) — CFR ~48.0% — up +57 cases and +29 deaths from the 5,656/2,715 figure used yesterday, with new cases from Ituri (34), North Kivu (18) and Haut-Uele (5). Ituri remains the epicenter at 4,750 cases and 2,133 deaths (28 of 36 health zones); North Kivu stands at 753 cases and 512 deaths (13 of 34 health zones); 770 patients are hospitalized in isolation. AP additionally lists a health workers' strike among the conditions fueling spread, alongside insecurity, displacement and intense population movement — a recurrence of the pay-related stoppages this brief has tracked since July. No new provinces (still six), no confirmed South Sudan/CAR/other new-country cases, no new American/international cases, no confirmed Kinshasa transmission, no PHEIC status change, no PARTNERS trial results yet. The outbreak is now on Day 106 (PHEIC Day 104). (Associated Press via PBS NewsHour / Washington Post / Anchorage Daily News, Aug 27; DRC INSP case data via ECDC, Aug 26)
Superseded (Aug 27) — WHO confirms Uganda's Ebola outbreak is officially over; DRC case count rises to 5,656/2,715 (CFR ~48.0%): WHO and Uganda's Ministry of Health jointly announced Aug 26 that Uganda's Ebola outbreak has ended, having completed the mandatory 42-day enhanced monitoring period without a new case since the last patient was discharged from Kampala's Mulago National Referral Isolation Centre on July 16; Uganda's final toll stands at 20 confirmed cases and 2 deaths, all travel-linked to DRC, with the border to DRC remaining closed as a precaution. Separately, DRC's case count has advanced to 5,656 confirmed cases and 2,715 deaths (data thru Aug 24) — CFR ~48.0% — up +141 cases and +73 deaths from the 5,515/2,642 figure used since Aug 25; Ituri remains the epicenter with 4,716 cases and 2,119 deaths across 28 of 36 health zones. The Washington Post reported Aug 26 that the DRC response continues to be hampered by a severe funding shortfall and pervasive misinformation on the ground. No new provinces (still six), no confirmed South Sudan/CAR/other new-country cases, no new American/international cases, no confirmed Kinshasa transmission, no PARTNERS trial results yet. The outbreak is now on Day 105 (PHEIC Day 103). (WHO/Uganda Ministry of Health joint announcement via Al Jazeera, Aug 26; Washington Post, Aug 26; DRC government case data, Aug 25)
Superseded (Aug 26) — WHO publishes revised Temporary Recommendations from the Aug 18 IHR Emergency Committee meeting; new social-measures section formalizes river surveillance toward Kinshasa; land-border risk list widens to nine countries: No newer official case count has been published beyond 5,515 confirmed cases and 2,642 deaths (data thru Aug 23) — that remains the latest official figure; the outbreak is now on Day 104 (PHEIC Day 102). WHO published the formal written outcome of the second IHR Emergency Committee meeting (held Aug 18) as a revised set of Temporary Recommendations on August 24 — the first substantive update since the initial recommendations issued May 22. The most notable addition is a brand-new section specific to DRC on "social measures, mass-gathering events, and domestic mobility," including postponing mass gatherings in areas with active transmission, reducing crowding in food and drink establishments and nightclubs, limiting motorbike passengers to one, safe-school-reopening measures, 24/7 health checkpoints on roads linking transmission areas to at-risk areas, and — notably — BVD surveillance on inland waterway vessels connecting transmission areas to major urban centers, explicitly including the capital Kinshasa, formalizing into a standing recommendation the river-corridor screening this brief has tracked informally since the Aug 6 Yingfeng 2 river-boat incident. The recommendations also confirm WHO's land-border risk tier now formally names nine countries at elevated cross-border risk — Angola, Burundi, Central African Republic, Republic of the Congo, Rwanda, South Sudan, Tanzania, Uganda and Zambia — a wider list than the three (Uganda, South Sudan, CAR) previously cited in this brief; this is a standing risk classification, not evidence of any new case or transmission event in those additional countries. Separately, Africa CDC's Dr. Yap Boum told Bloomberg (Aug 20) the outbreak is displaying several characteristics considered when assessing pandemic-emergency status, though he stopped short of recommending that separate, higher formal designation, which rests with WHO alone — noted here as added framing context, not a status change; the outbreak's classification remains a PHEIC, and no pandemic-emergency declaration has been made. No new provinces (still six), no confirmed South Sudan/CAR/other new-country cases, no new American/international cases, no confirmed Kinshasa transmission, no PARTNERS trial results yet. Uganda's 42-day enhanced monitoring window closes tomorrow, Aug 27. (WHO statement, Aug 24 — Temporary Recommendations; Bloomberg, Aug 20 — Yap Boum/pandemic-emergency framing)
Superseded (Aug 25) — 100 days since declaration; case count jumps to 5,515/2,642 (CFR nearing 48%); WHO calls response gains "extraordinary" but insufficient; South Sudan aid workers abducted transporting Ebola supplies: DRC government data reported Aug 24 puts the outbreak at 5,515 confirmed cases and 2,642 deaths — CFR ~47.9% — up +225 cases and +126 deaths from the 5,290/2,516 figure used since Aug 22, with 51 new cases from Ituri and North Kivu in the latest 24h period; the outbreak is now on Day 103 (PHEIC Day 101), having just passed its 100th day since the May 15 declaration. WHO's 100-day retrospective (Dr. Marie Roseline Belizaire, WHO AFRO) calls the response's scale-up "extraordinary" — testing grew from 1 site to 19 labs (3,000+ samples/day), treatment beds from under 10 to 1,300+, community outreach reached 2.5M+ people, and contact tracing of registered contacts rose from 9% in week one to 84% as of Aug 18 — but stressed it is "not yet sufficient" to end the epidemic. WHO's five priorities going forward: strengthen community engagement, push tracing to 95%, expand beds to 3,000, improve healthcare-worker protection, and strengthen cross-border preparedness. The healthcare-worker toll is cited at 155–160 infected and 45–50 dead across two WHO-linked Aug 24 sources — an incremental rise from 155/45. New security development: the UN confirmed four aid workers were abducted in southwestern South Sudan while transporting Ebola medical supplies toward the border town of Libogo — the first attack directly targeting Ebola-response logistics outside DRC; no cases confirmed in South Sudan. The Red Cross separately reported several responders injured in DRC attacks over the past week. Pope Leo XIV appealed Sunday for scaled-up international action. No new provinces (still six), no confirmed South Sudan/CAR cases, no new American/international cases, no confirmed Kinshasa transmission, no new PHEIC statement, no PARTNERS trial results yet. Uganda's 42-day monitoring window closes Aug 27, two days from now. (Al Jazeera/AP, Aug 24 — case count, Pope Leo; UN News "100 days" retrospective, Aug 24, citing WHO; Euronews, Aug 24 — Red Cross)
Superseded (Aug 24) — First vaccine doses physically land in Kinshasa; Africa CDC quantifies the tracing gap at 16% of expected contacts; North Kivu's CFR runs far above the national average: No newer official case count has been published beyond 5,290 cases / 2,516 deaths (data thru Aug 19) — that remains the latest WHO/Africa CDC figure; the outbreak is now on Day 102 (PHEIC Day 100). The most concrete development: the first tranche of the 70,000 Ervebo doses approved Aug 20 has physically arrived — 16,250 doses landed at N'Djili International Airport in Kinshasa late Aug 21, moving vaccine access from an approval to an on-the-ground fact for the first time this outbreak; onward distribution to the Phase 3 trial and frontline responders in Ituri/North Kivu is not yet confirmed in available reporting. Africa CDC's Dr. Yap Boum gave a sharper contact-tracing figure than the "~10% of expected contacts listed" estimate already carried in this brief: based on an average of 60 contacts per confirmed case, responders should have identified roughly 100,000 contacts from the ~1,663 cases confirmed in a recent three-week window, but the actual tracing rate came out to just 16% of that expected total, and only 20% of health alerts currently originate from within affected communities. Separately, 97% of deaths reported on Aug 17 occurred in the community rather than in a treatment centre, and the national CFR of 46.7% conceals a sharp geographic split, reaching 68.2% in North Kivu specifically. The healthcare-worker toll has been updated to 155 infections and 45 deaths among frontline staff, up from the ~100-infected figure cited earlier in this brief. South Kivu remains a rare bright spot, with no new confirmed cases there since May 29 — a 79+ day streak. WHO's Rapid Risk Assessment v4 (Aug 20) rates outbreak risk "very high" within DRC, "high" for bordering countries (Uganda, South Sudan, CAR), and "low" for the wider African region and globally. No new provinces (still six), no confirmed South Sudan/CAR cases, no new American/international cases, no confirmed Kinshasa transmission (the vaccine shipment landing at the capital's airport is a logistics point, not a case), no new PHEIC statement, no PARTNERS trial results yet. Uganda's outbreak remains closed (declared over Jul 28; 42-day monitoring closes Aug 27, three days from now). (Al Jazeera/AP/ABC News, Aug 22 — Ervebo arrival; MedPage Today, Aug 22, citing Africa CDC — tracing rate; WHO Rapid Risk Assessment v4, Aug 20; ECDC situation update, Aug 21)
Superseded (Aug 23) — Africa CDC: true case burden may be up to 3x reported (est. 10,000–15,000 cases); Congo River initiative launched; UN warns funding runs out within weeks: No newer official case count has been published beyond 5,290 cases / 2,516 deaths (data thru Aug 19) — that remains the latest WHO/Africa CDC figure, and today marks 100 days since the May 15 declaration. Africa CDC officials Dr. Yap Boum II and Kyeng Mercy said at an Aug 20 online briefing that joint modeling with DRC's INRB suggests confirmed cases represent only 30–40% of actual infections, implying a true burden of roughly 10,000–15,000 cases — explicitly flagged as a model-based estimate with uncertainty, not a revised official count, citing that fewer than 10% of detected cases are among known contacts and fewer than 40% have a confirmed epidemiological link. The DRC government separately launched the "Congo River Without Ebola" initiative Aug 20 — a three-month, $9 million (UN OCHA catalytic funding) river-surveillance push with reinforced port screening, floating mobile labs, and preparations for possible vessel quarantine, aimed at protecting Kinshasa (~20 million people, still zero cases) and blocking cross-border spread toward the Republic of the Congo and Central African Republic — Africa CDC flagged growing Bas-Uele transmission near the CAR border as an urgent concern. UN Senior Ebola Coordinator Julien Harneis warned Aug 21 the outbreak is "spreading faster and wider" than ever, citing 260+ attacks on health workers over six months (8 killed, 43 died after falling ill) and warning existing response funding will run out within weeks. Africa CDC's Kaseya acknowledged Aug 19 that "the approach has not been the best," signaling further shift to the village-centered response model. No new provinces, no confirmed South Sudan/CAR cases, no new American/international cases, no confirmed Kinshasa transmission, no new PHEIC statement, no PARTNERS trial results yet. Uganda's outbreak remains closed (declared over Jul 28; 42-day monitoring ends Aug 27). (Africa CDC online briefing, Aug 20; CGTN/Xinhua, Aug 22; UN/Al Jazeera, Aug 21)
Superseded (Aug 22) — Routine data update, no status change: WHO and Africa CDC's latest release (Aug 20, data thru Aug 19) puts the outbreak at 5,290 confirmed cases and 2,516 deaths — CFR ~47.6% — with 837 patients hospitalized in isolation and 1,152 recoveries, up +82 cases / +40 deaths from the 5,208/2,476 figure (data thru Aug 18) used in the Aug 21 brief; WHO/Africa CDC's own reported delta for the period was +81 cases and +40 deaths (Ituri +56, North Kivu +18, Haut-Uele +7). Ituri remains the epicenter with 4,447 cases and 1,984 deaths across 28 of 36 health zones; North Kivu has 663 cases and 452 deaths across 12 of 34 health zones. Contact follow-up is now cited at 82.9% of identified case contacts. No newer case-count report has been found beyond this figure as of this update. No new provinces (still six), no confirmed South Sudan or Central African Republic cases, no new American or international cases, no confirmed Kinshasa transmission — DRC Health Minister Kamba's Aug 21 assurance stands unchanged. No new PHEIC statement beyond the 2nd IHR Emergency Committee's confirmation (delivered Aug 18, reported Aug 20-21) that the emergency continues. No new vaccine-access decision beyond the 70,000-dose Ervebo release announced Aug 20; the PARTNERS trial (remdesivir/MBP134) continues enrolling, with preliminary results still expected in the "three to four weeks" window cited Aug 21. Uganda's outbreak remains closed (declared over Jul 28; 42-day enhanced monitoring runs through Aug 27). (WHO/Africa CDC situation update, Aug 20, data thru Aug 19)
Superseded (Aug 21) — First vaccine doses released; WHO confirms PHEIC status continues: WHO and Africa CDC announced August 20 that the ICG has approved an immediate release of 70,000 Ervebo (rVSV-ZEBOV) doses to DRC from the global Ebola vaccine stockpile — the outbreak's first concrete vaccine deployment decision. 20,000 doses go to a Phase 3 randomized clinical trial testing whether the licensed Zaire-strain vaccine cross-protects against Bundibugyo virus; 50,000 doses go to frontline and health-worker vaccination under WHO SAGE guidance. It remains unknown whether Ervebo is protective against Bundibugyo virus in humans — early lab and animal data suggest only possible partial protection. Separately, WHO Director-General Tedros told the second IHR Emergency Committee meeting (held Aug 18) that the outbreak remains a Public Health Emergency of International Concern, resolving the "outcome pending" status carried since Aug 18: "the epidemic is far from being under control... it had a big head start, and we are still playing catch-up." DRC health authorities now report 5,208 confirmed cases and 2,476 deaths (data thru Aug 18) — CFR ~47.5% — across 56 of 151 health zones, up +187 cases / +98 deaths from the prior WHO AFRO figure. Africa CDC warned Aug 18 the outbreak is now killing roughly one person every 30 minutes and, unless reversed, "risks becoming the deadliest Ebola outbreak ever recorded globally." DRC Health Minister Roger Kamba confirmed no cases in Kinshasa and flagged Tshopo/Kisangani's river-road-air links to the capital as a corridor of concern, with river-route screening stepped up. WHO added the Central African Republic to its list of countries at elevated risk of imported cases, alongside Uganda and South Sudan. No new provinces, no confirmed South Sudan cases, no new American/international cases. (WHO news release, Aug 20; WHO Director-General remarks, Aug 18)
Aug 20 — WHO's own regional office publishes a higher case count than DRC's national figure; IHR Committee outcome still not published: WHO's Regional Office for Africa (AFRO) published a regional situation report on August 18 (data through August 16) putting the outbreak at 5,021 confirmed cases and 2,378 deaths — a CFR of roughly 47.4% — with 1,061 recoveries and 751 patients hospitalized in isolation. This is a WHO regional figure for the same data-through date as the DRC INSP count used in yesterday's update (4,945/2,325) but runs higher, and postdates it — it is treated here as the latest official number. Versus the prior report, that is +76 cases and +53 deaths. Ituri remains the epicenter with 4,257 cases and 1,878 deaths across 28 of its 36 health zones; North Kivu has 607 cases and 428 deaths across 12 of 34 health zones; Haut-Uele 139 cases/63 deaths; Tshopo 14 cases/7 deaths; South Kivu 3 cases/1 death. No formal outcome or statement from the second IHR Emergency Committee meeting (held Aug 18) has been published as of this update — PHEIC status is carried forward unchanged, pending that statement. No new provinces (still six), no confirmed South Sudan cases, no new American or international cases, no confirmed Kinshasa transmission, and Uganda's outbreak remains closed (declared over Jul 28; 42-day enhanced monitoring runs through Aug 27). No new vaccine-access decision beyond DRC's standing request for 100,000 Ervebo doses from the ICG; the PARTNERS treatment trial (MBP134/remdesivir) continues enrolling with no results reported. (WHO AFRO regional situation report, Aug 18, data thru Aug 16)
Superseded (Aug 19) — Second IHR Emergency Committee meets in Geneva; Israel's third suspected case resolved negative: The second meeting of the IHR Emergency Committee on this outbreak was held August 18 in Geneva, chaired by Prof. Lucille Blumberg, with representatives of DRC, Uganda and France attending. In his published opening remarks, WHO Director-General Tedros Adhanom Ghebreyesus told the Committee the outbreak has infected "almost 5000" people and killed "more than 2,300" across six provinces and 55 health zones — consistent with, not additive to, the existing 4,945/2,325 figure reported Aug 17 — and said bluntly: "We must be frank: the epidemic is far from being under control... It had a big head start, and we are still playing catch-up." He confirmed Uganda has stopped transmission following its initial spillover, that a traveller carried the virus to France last month with no secondary transmission detected, that the WHO-sponsored PARTNERS treatment trial has now enrolled 100 patients, and that two Bundibugyo-specific vaccines have entered human trials for the first time, with a third showing cross-protection in animal studies and advancing toward a Phase 3 trial. No formal Committee statement or outcome on PHEIC status has been published as of this update — the emergency remains in effect unchanged pending that statement. Separately, Israel's third suspected case (Soroka Medical Center, reported Aug 11) has been resolved: the patient tested negative for Ebola. All three Israeli suspected cases during this outbreak have now tested negative, and Israel still has no confirmed case. (WHO Director-General's opening remarks, Aug 18; Israeli press reporting)
Superseded (Aug 18) — Outbreak becomes the deadliest Ebola epidemic in DRC's history: WHO said Monday, August 17, that the death toll — now 2,325 — has surpassed the 2,299 deaths recorded in the DRC's 2018–2020 North Kivu epidemic, making this the deadliest Ebola outbreak the country has ever faced. DRC's National Public Health Institute (INSP) puts the latest count at 4,945 confirmed cases and 2,325 deaths — a CFR of roughly 47.0% (cited elsewhere as "~46%") — with 1,040 recoveries and 730 patients hospitalized in isolation, as of data through August 16, reported Sunday, August 17. That's up from the 4,727/2,214 figure used in yesterday's update (+218 cases, +111 deaths over two days), including +101 cases and +53 deaths in the most recent single 24-hour period — new cases from Ituri (89), North Kivu (8), Haut-Uele (3) and Tshopo (1). Deaths are being recorded at a rate of roughly one every 28 minutes over the past week, per WHO. WHO Director-General Tedros Adhanom Ghebreyesus warned that at its current pace the outbreak is "almost certain" to eventually eclipse the 2014–2016 West Africa epidemic (28,616 cases / 11,310 deaths) too, unless testing, contact tracing and isolation are drastically scaled up — this brief notes the outbreak remains the second-largest Ebola outbreak by case count and is still far short of West Africa's death toll, so "deadliest in DRC's history" and "largest/deadliest ever recorded" remain two distinct claims, and only the first is true today. The IHR Emergency Committee is scheduled to reconvene today, August 18, to reassess PHEIC status; no outcome has been reported as of this update. No new provinces, no confirmed South Sudan cases, no new American or international cases, no confirmed Kinshasa transmission, Israel's third suspected case still unresolved in available reporting, and Uganda's outbreak remains closed (declared over Jul 28). (UN News, CGTN, Al Jazeera, Techtimes, Irish Times, Bloomberg — citing WHO and DRC government data, Aug 17)
Superseded (Aug 17) — Case count rises to 4,727 / 2,214; more than 63% of deaths now occurring in communities, not treatment centres: The DRC health authorities' latest report, released Friday and reported by CGTN/Xinhua on August 16, puts the outbreak at 4,727 confirmed cases and 2,214 deaths — a CFR of 46.8%, with 976 recoveries — up from 4,665/2,184 in yesterday's update (+62 cases, +30 deaths). Affected health zones rise to 55 (from 54) across the same six provinces, with Ituri still the epicenter and Buta (Bas-Uele) the newest affected zone. The most operationally significant disclosure: Africa CDC Director-General Dr. Jean Kaseya said more than 63% of Ebola deaths are now occurring in communities rather than in treatment centres or hospitals. That figure both explains and compounds the tracing failure already documented in this brief — a death outside the health system leaves responders with no record of who the patient contacted before or after death, and makes safe and dignified burial substantially harder. The same report puts contact follow-up at 82.6% of registered contacts (up marginally from the 82.4% in AFRO Sitrep 13), with Africa CDC again stressing that the proportion of registered contacts being followed does not itself reflect tracing effectiveness when most contacts are never identified in the first place — consistent with the ~10%-of-expected-contacts-listed figure. WHO's Tedros said on August 12 that many new cases continue to be detected among people not on existing contact lists, indicating transmission chains that have yet to be identified. No PHEIC status change; the IHR Emergency Committee reconvenes tomorrow (Aug 18). No new provinces, no confirmed South Sudan cases, no new American or international cases, no confirmed Kinshasa transmission, Israel's third suspected case still unresolved in available reporting, and Uganda's outbreak remains closed (declared over Jul 28). (CGTN/Xinhua citing DRC health authorities and Africa CDC — Aug 16)
New (Aug 17) — Africa CDC to retrospectively reconstruct the outbreak's undocumented February–May period: Africa CDC is pushing a village-based response that would, alongside forward surveillance, attempt to reconstruct the epidemic's pre-declaration phase. Communities will be asked to identify people who died or fell ill with Ebola-like symptoms between January and May 2026; where laboratory confirmation is no longer possible, community recall could still let authorities estimate how much transmission occurred before the outbreak was formally detected on May 15. Kaseya was blunt about the gap: "We have no clue about what happened from February to May," adding that figures collected since the declaration should not necessarily be regarded as a complete picture of the epidemic. Dr. Chikwe Ihekweazu, executive director of the WHO Health Emergencies Programme, said investigations so far suggest the virus may have been circulating two to three months before formal detection, though the exact start of transmission remains under investigation. This corroborates WHO AFRO Regional Director Dr. Mohamed Janabi's August 10 statement that genomic sequencing points to a February 2026 start in Mongbwalu, with early cases misattributed to malaria and typhoid. Analytical note: if the reconstruction confirms a February start, current case counts represent a floor rather than a full accounting, and growth-rate comparisons against the 2014–2016 West Africa epidemic — measured from declaration date — would understate this outbreak's true velocity. (CGTN/Xinhua citing Africa CDC and WHO — Aug 16)
Superseded (Aug 16) — Case count rises to 4,665 / 2,184; DRC requests 100,000 Ervebo doses for expanded emergency vaccine use: DRC public health authorities, via an Africa CDC online briefing reported by CGTN/Xinhua on August 15, put the outbreak at 4,665 confirmed cases and 2,184 deaths — a CFR of 46.8%, with 965 recoveries and 634 patients hospitalized in isolation — up from the 4,566/2,128 figure used in yesterday's update. The health zone of Buta (Bas-Uele) has been added to DRC's own list of affected areas, bringing the total to 54 health zones across six provinces. The most significant development: Africa CDC Director-General Dr. Jean Kaseya announced DRC has requested 100,000 doses of the licensed ERVEBO vaccine from the International Coordinating Group (ICG) for expanded emergency use — a step beyond the Phase 3 ring trial reported Aug 7 — to vaccinate frontline responders, high-risk contacts, healthcare workers, burial teams, and religious/village leaders in high-transmission areas, while generating scientific evidence on cross-protection against Bundibugyo virus. Kaseya: "The current emergency risks becoming the deadliest the country has faced, and we cannot allow that trajectory to continue." The expanded-use decision was among measures agreed at last week's Kinshasa crisis meeting between President Tshisekedi, Kaseya, and WHO's Tedros. No PHEIC status change; the IHR Emergency Committee reconvenes in 2 days (Aug 18). Israel's third suspected case (Soroka Medical Center) remains unresolved in available reporting. No confirmed South Sudan cases (DRC cases remain ~35km from the border). No new American/international cases, no confirmed Kinshasa transmission, and Uganda's outbreak remains closed (declared over Jul 28). (CGTN/Xinhua, Africa CDC briefing — Aug 15)
Superseded (Aug 15) — Case count refined to 4,566 / 2,128; Kaseya warns outbreak could run "more than a year" and become the largest in the world: DRC government data reported by Al Jazeera/AP on August 14 (figures thru August 11) puts the outbreak at 4,566 confirmed cases and 2,128 deaths — a CFR of 46.6% — essentially confirming the "4,500+/2,100+" AP estimate used in yesterday's update. Speaking on the Bas-Uele expansion, Africa CDC Director-General Dr. Jean Kaseya delivered his starkest warning yet: "If we do not stop this outbreak, it will last more than a year and will be the largest in the world." That echoes WHO Director-General Tedros's August 12 assessment that the epidemic is on track to surpass the 2014–2016 West Africa outbreak. Separately, WHO's regional situation report (AFRO Weekly External Sitrep 13, data as of Aug 9) puts contact follow-up at 82.4% of already-listed contacts across Ituri, North Kivu, South Kivu, Haut-Uele and Tshopo — a different pipeline stage than Africa CDC's Aug 13 figure that only ~10% of expected contacts have been listed in the first place; the two figures are not in conflict, but together they show a tracing system that is both under-registering contacts and, for the minority it does register, following most of them. Local reporting (Radar Africa, Aug 14) also clarifies that Bas-Uele has not yet been formally added to WHO's official list of affected provinces, since authorities have not yet confirmed local (secondary) transmission there — contact tracing on the index case's known contacts is ongoing. No PHEIC status change; the IHR Emergency Committee reconvenes in 3 days (Aug 18). No new American or international cases, no confirmed Kinshasa transmission, and Uganda's outbreak remains closed (declared over Jul 28). (Al Jazeera/AP, PBS/Reuters, WHO AFRO, Radar Africa — Aug 14)
New (Aug 14) — Outbreak reaches a sixth province; Africa CDC says contact tracing "has become useless": Africa CDC Director-General Dr. Jean Kaseya confirmed the outbreak has spread to a sixth of DRC's 26 provinces after a motorcycle-taxi driver died in Buta, capital of the previously unaffected Bas-Uele province, having traveled there from Isiro in Haut-Uele. Congo's National Institute for Biomedical Research (INRB) director Jean-Jacques Muyembe said the man's colleagues tried to forcibly take his body before police intervened — raising concern that more people were exposed. AP now puts the outbreak at more than 4,500 confirmed cases and over 2,100 deaths on the latest government figures, a toll reached almost three times faster than the 2014–2016 West Africa epidemic. Kaseya delivered the response's bluntest assessment yet: "the concept of contact tracing in DRC has become useless." WHO's Regional Director for Africa, Dr. Mohamed Janabi, added: "We are chasing the virus; the virus is ahead of us." Separately, health workers at the Nizi Treatment Center in Ituri — one of the most-affected facilities — struck Aug 13 over three months of unpaid wages, forcing its temporary closure; Kaseya called on the DRC government to release outstanding salaries, saying funds are available. Aid group Mercy Corps separately warned that cases have been reported along a travel route roughly 35km from DRC's border with South Sudan, citing concern over the outbreak's "widening footprint" — no cases have been confirmed in South Sudan. (AP via KSAT/Washington Times, Aug 13)
New (Aug 14) — Nature Medicine study: outbreak began with a new, independent animal-to-human spillover, not a re-emergence: A genomic study published this week in Nature Medicine, analyzing samples from 22 patients in DRC and Uganda, found the outbreak strain is genetically distinct from the Bundibugyo viruses behind the 2007 and 2012 outbreaks — indicating a new zoonotic spillover event from an as-yet-unidentified animal reservoir, rather than continued circulation or re-emergence of a previously known human-outbreak lineage. The study links the Uganda outbreak to the same spillover. Infectious-disease physician Dr. Krutika Kuppalli cautioned this does not mean a new form of Ebola has emerged or that transmission dynamics have changed — "after that initial spillover, the outbreak has been driven predominantly by human-to-human transmission." Separately, WHO's Dr. Abdirahman Mahamud said the agency's moderate projection has the outbreak peaking within six months, with a more severe scenario running 9–12 months, and confirmed two Bundibugyo-specific vaccine candidates have now entered human testing for the first time, alongside the Oxford Phase 1 trial already underway.

New (Aug 13) — Tedros: outbreak now on track to become the largest Ebola epidemic ever recorded; case count rises past 4,500 / 2,060 deaths: WHO Director-General Dr. Tedros Adhanom Ghebreyesus told a Geneva press conference on August 12 that the epidemic is "already the second-biggest Ebola epidemic on record, and it's moving faster than any previous Ebola outbreak. At its current pace, it's on track to eclipse the West African Ebola outbreak of 2014-2016" — which killed 11,310 people across Guinea, Liberia and Sierra Leone. As of Monday, August 10, WHO figures cited by Tedros put the outbreak at more than 4,500 confirmed cases and more than 2,060 deaths, running ahead of the Aug 11 DRC government count (4,381/2,011) used in yesterday's update. Separately, WHO's Dr. Vasee Moorthy said the agency is finalizing a Phase 3 vaccine-trial protocol for submission to DRC regulatory and ethics authorities: known contacts of cases would be individually randomized — not assigned by ring-vaccination as in the 2016 Guinea "Ebola Ça Suffit" trial that proved Ervebo's ~84% efficacy against Ebola Zaire — to receive Ervebo or placebo, with Bundibugyo-specific candidates (Oxford, Moderna's mRNA candidate, IAVI) potentially added once September Phase 1 data are in. DRC authorities have separately asked to roll out Ervebo for general use outside a clinical trial, a request backed by Africa CDC, though it remains unclear whether DRC can access sufficient doses from the 500,000-dose Gavi stockpile, which is controlled by the International Coordinating Group on Vaccine Provision (ICG). (STAT News/Helen Branswell, Aug 12, citing WHO Geneva briefing)
New (Aug 13) — Africa CDC: only ~10% of expected contacts listed; outbreak now spans 53 health zones: Africa CDC disclosed that just 10% of expected contacts have been listed — far short of the 95% operational target — and that only about 70% of those listed are being actively followed. Roughly four in five new infections are occurring outside known transmission chains, and more than 60% of deaths are happening in communities rather than treatment centres. The outbreak has now spread to 53 health zones across five provinces, up from 51, having expanded from just 11 health zones in one province at the May 15 declaration. Africa CDC nonetheless commended the DRC government for advancing a package of "bold and innovative measures," including large-scale vaccination planning and a village-centred response aimed at identifying every suspected case and death. (Africa CDC statement, CGTN, Aug 12)
Watch (Aug 13) — Israel's third suspected case still pending; no confirmed resolution found: The suspected case reported Aug 11 — a 24-year-old man hospitalized in isolation at Soroka Medical Center after returning from DRC with fever — had test results expected within 24 hours as of that report. No confirmed test-result announcement has been located as of this update. Both of Israel's two prior suspected cases this outbreak (at Sheba Medical Center and Rambam Health Care Campus) later tested negative; this is not yet a confirmed case.
Aug 12 — Death toll passes 2,000; case count rises to 4,381 / 2,011 deaths: DRC government data reported by AP/Al Jazeera puts the outbreak at 4,381 confirmed cases and 2,011 deaths as of Tuesday, August 11 — a CFR of 45.9% — up from the Aug 8 WHO/Africa CDC sitrep of 4,209/1,916. The death toll has now crossed 2,000 for the first time, and officials say more than 1,000 of those deaths occurred in just the last three weeks alone. It remains the fastest-growing Ebola outbreak on record and the second-largest ever documented, behind only the 2014–2016 West Africa epidemic (11,310 deaths). (AP via Al Jazeera, Washington Post, Euronews, Aug 11)
New (Aug 12) — WHO: outbreak actually began in February, months before declaration; suspected case under investigation in Israel: WHO Regional Director for Africa Dr. Mohamed Janabi told reporters August 10 that genomic sequencing indicates the outbreak's true start was February 2026 in Mongbwalu, Ituri — roughly three months before the May 15 official declaration — with early cases misattributed to malaria and typhoid, allowing undetected spread during that window. Separately, Israel's Ministry of Health said it is investigating a suspected case: a 24-year-old man who recently returned from DRC was hospitalized in isolation at Soroka Medical Center (Beersheba) with fever; results were expected within 24 hours as of Aug 11. This is the third such suspected case in Israel during this outbreak — the two prior cases both later tested negative — and it is not yet a confirmed case. Separately, Africa CDC said the DRC government is submitting a formal request to the ICG on August 12 to release Ervebo vaccine doses from the Gavi global stockpile, following national ethics and regulatory approval, to support the Phase 3 ring trial recommended Aug 7. (WHO/Africa CDC press briefings; Times of Israel, ynetnews, Aug 10–11)
New (Aug 11) — Case count rises to 4,209 / 1,916 deaths; Africa CDC shifts to door-to-door case-finding: The most recent WHO/Africa CDC sitrep (published Aug 8, data thru Aug 7) puts the outbreak at 4,209 confirmed cases and 1,916 deaths — a CFR of 45.5% — up 89 cases and 21 deaths from the prior day, with 595 patients hospitalized in isolation. Ituri remains most affected with 3,636 cases and 1,551 deaths across 28 of its 36 health zones. Separately, Bloomberg and the Japan Times reported August 10 that Africa CDC and partners are shifting from conventional contact tracing to active door-to-door case-finding in the hardest-hit areas, where widespread community transmission means almost anyone could have been exposed — the effort will deploy an estimated 25,000–30,000 community health workers. Officials explicitly caution the confirmed case count is likely to climb further in the coming weeks as previously undetected infections are found — a surveillance-capacity expansion, not necessarily a sign transmission itself is accelerating. (WHO/Africa CDC sitrep, Aug 8; Bloomberg/Japan Times, Aug 10)
New (Aug 11) — Child deaths pass 300: UN News reported August 7 that more than 300 children have now died in the outbreak. Children make up nearly a quarter of confirmed cases but almost a third of all deaths — a disproportionate mortality burden. WHO's Technical Advisory Group met for a third time on July 31 to review additional animal-study data on ERVEBO cross-protection ahead of the Phase 3 ring-trial recommendation issued Aug 7 (see below). Nearly one million people remain displaced by armed conflict in Ituri, with women and children accounting for roughly 80% of that displaced population — the same group bearing the heaviest share of Ebola mortality. (UN News, Aug 7)
New (Aug 9) — River-boat scare resolved: all Yingfeng 2 passengers test negative, vessel released: DRC's National Institute of Biomedical Research (INRB) confirmed on August 9 that every passenger and crew member screened aboard the quarantined Yingfeng 2 — not just the initial 7 reported August 7 — tested negative for Bundibugyo virus. The Health Ministry said the vessel was decontaminated and the quarantine at Maluku/Bende Bende port, 65km upstream from Kinshasa, has been lifted. This closes out the first concrete real-world test of the Kisangani–Congo River–Kinshasa corridor without a confirmed importation into the capital. Cholera screening was also conducted alongside the Ebola testing. (AP via Washington Post, ABC News, Aug 9)
New (Aug 7) — WHO recommends full-scale Phase 3 trial of the licensed ERVEBO vaccine against Bundibugyo: WHO's Technical Advisory Group on vaccine prioritization recommended that the licensed ERVEBO (rVSV-ZEBOV) vaccine — used successfully against the Zaire strain since 2018 — be fast-tracked directly into a Phase 3 ring trial in DRC to test possible cross-protection against Bundibugyo virus. This reverses WHO's earlier May 2026 recommendation against deploying ERVEBO in this outbreak. The recommendation rests on preclinical data showing 3 of 4 non-human primates vaccinated with ERVEBO survived Bundibugyo challenge, and a ferret study in which the research-grade version gave 100% protection. Gavi confirmed its 500,000-dose global Ebola vaccine stockpile will supply the ring trial, with some doses already in DRC. Because ERVEBO is an already-licensed, mass-manufactured product — unlike the small Phase 1 Oxford ChAdOx1 BDBV trial (50 participants) — this is the most significant near-term vaccine-access development since the outbreak began, though efficacy against this strain in humans remains unproven pending trial results. (Al Jazeera, Gavi, Aug 7)
Aug 6–7 — River boat carrying 255 passengers quarantined 65km from Kinshasa after 5 deaths; onboard tests negative so far: The Yingfeng 2, a Chinese-operated river boat that departed Kisangani (Tshopo Province) and travelled roughly 1,700km down the Congo River toward the capital, was intercepted and quarantined near Bende Bende/Maluku port — just 65km upstream from Kinshasa — on August 6. The alert was triggered after a passenger with fever and diarrhoea, who had disembarked in Mongala Province, died on July 25 with Ebola-like symptoms; DRC Health Minister Roger Kamba subsequently confirmed 5 total deaths connected to the vessel's journey — the index passenger plus two adults, a 3-year-old child and a newborn. WHO and Ministry of Health teams boarded the vessel with a mobile lab to screen all 255 passengers and crew; the first 7 tested came back negative on August 7, easing immediate concern, though Kamba cautioned the 21-day incubation window has not fully elapsed. Officials also clarified that Mongala Province itself has recorded no confirmed Ebola cases. This is the most concrete real-world test yet of the Kisangani–Congo River–Kinshasa transmission corridor this brief has long flagged as the highest-risk escalation pathway to the capital; Kinshasa authorities say surveillance and rapid-response capacity at the Maluku entry point are being reinforced. (BBC via Kahawatungu, Aug 6; US News/AP, Aug 7)
New (Aug 7) — Confirmed cases surpass 4,000 for the first time; DRC INRB now counts 4,053 cases / 1,850 deaths: The DRC's public health institute (INRB), reported by AFP via US News on August 7, puts the outbreak at 4,053 confirmed cases and 1,850 deaths — a CFR of 45.6% — up from the WHO/Africa CDC joint figure of 3,973/1,801 issued the day before. This is the first time confirmed cases have crossed the 4,000 threshold in this outbreak, which remains the fastest-growing Ebola epidemic on record, having reached this scale roughly ten weeks after the outbreak's May 15 declaration.
New (Aug 6–7) — Ebola virus reaches internally displaced persons camps in Ituri: UN News, citing UNHCR, reports the rapidly spreading Bundibugyo virus has now infected 19 internally displaced people, killing 5, across at least 5 of Ituri Province's 69 displacement camps. Camps housing some of the roughly 270,000 people displaced by armed conflict in Ituri typically lack adequate water and sanitation infrastructure, and residents often distrust health services — conditions UNHCR and WHO both flag as favorable to continued spread. This marks a new and higher-risk transmission environment beyond the health-facility and community settings already driving the outbreak.
Aug 6 — WHO/Africa CDC joint mission briefs President Tshisekedi; case count rises to 3,973/1,801, contact tracing at 75%, North Kivu beds at 139% of capacity: In a joint news release, WHO and Africa CDC reported the outbreak at 3,973 confirmed cases, 1,801 deaths and 776 recoveries across 51 health zones in five provinces as of August 4 — a CFR of 45.3% — with 99 new cases and 52 deaths in the latest 24-hour period. Contact follow-up stood at just 75%, well short of the 95% target needed to trace transmission chains quickly, and treatment-centre occupancy in North Kivu reached 139%, well past capacity, with 674 patients under care nationwide. Dr. Tedros, Africa CDC's Dr. Jean Kaseya, and WHO AFRO's Dr. Mohamed Janabi led a joint high-level mission August 4–6 through Kampala, Bunia and Kinshasa — visiting Bunia's Rwangole Ebola Treatment Centre and briefing President Félix Tshisekedi directly. The two agencies issued a ten-point call for an urgent, community-led scale-up of the response — faster case detection, contact follow-up at 95%+, care and testing brought closer to affected villages, timely pay and protection for frontline workers, and financing that reaches operations "without delay." Tedros: "In some areas of eastern DRC, the Ebola outbreak is outpacing our response." Kaseya: "Containing and ultimately stopping this outbreak will come from communities." (WHO/Africa CDC joint release, Aug 6)
New (Aug 4) — second Bundibugyo vaccine candidate enters trials in Canada; ERVEBO cross-protection data under review: WHO's Dr. Vasee Moorthy told reporters in Geneva that a second Bundibugyo-specific vaccine candidate has begun animal trials (ferrets and monkeys) in Canada, alongside the UK/Oxford ChAdOx1 BDBV candidate that entered human Phase 1 testing in July. Results from the DRC's post-exposure prophylaxis trial (obeldesivir) are also progressing, with more than 25 high-risk contacts enrolled and a fourth trial site opening in Ituri this week. Separately, WHO's technical advisory group met to review new animal-study data on whether the licensed ERVEBO vaccine (targeting the Zaire strain) offers any protection against Bundibugyo virus, with recommendations expected shortly. Moorthy cautioned that conclusive results on any candidate remain "several months" away. (UN News, Aug 4)
Superseded — Aug 4 DRC govt count jumps to 3,802 cases / 1,707 deaths; WHO warns of "exceptional" pace: The latest DRC government update, reported by AP on August 4, puts the outbreak at 3,802 confirmed cases and 1,707 deaths — a CFR of 44.9% — a sharp rise from WHO's July 30 count (3,605 / 1,587). On August 2 WHO said the epidemic is "intensifying" at an exceptional pace and called for a major scale-up of the response "to get ahead of the outbreak," citing insecurity, displacement and cross-border movement among roughly 270,000 people in Ituri displacement sites.
New (Aug 5) — Africa CDC: outbreak has grown "seven times faster" than 2014–16 West Africa; treatment capacity now ~1,000 beds: Speaking again in Bunia alongside WHO Regional Director for Africa Dr. Mohamed Janabi, Africa CDC's Kaseya said that after just 14 weeks the outbreak had grown seven times faster than the 2014–2016 West Africa epidemic did over the same period. The pair inaugurated a new Ebola treatment centre in Bunia; Janabi said treatment capacity has expanded to about 1,000 beds (up from 800) and daily lab testing remains above 2,000 samples (up from ~30 at the outbreak's start) — but stressed the response "remained insufficient as lives continued to be lost." No new case count, province, or PHEIC status change was reported. (Africanews, Aug 5)
Aug 4 — Africa CDC: "contact tracing is not working," peak timing unclear: Speaking in Bunia on his second visit to the epicentre, Africa CDC Director-General Dr. Jean Kaseya said it is not clear when the outbreak will peak and that 60–70% of new cases are now traced to community spread rather than known contact lists — "we don't like the trajectory of this outbreak, and it's already the second largest outbreak (ever) in the world." Patient zero has still not been identified, with displacement from armed conflict and illegal mining hampering efforts to trace thousands of contacts. WHO says it is now testing more than 2,000 samples a day (up from 20) and monitoring more than 17,000 contacts, with about 80% seen daily. WHO Director-General Tedros arrived in Kinshasa on August 4 and is expected to visit Bunia later this week. (AP/STAT)
New (Aug 3) — Mongbwalu health workers issue 24-hour pay ultimatum: Health care workers in the hard-hit town of Mongbwalu warned on August 3 that they would "escalate" action if unpaid wages were not resolved within 24 hours — the latest in a series of pay-related work stoppages (Bunia, July 13–15 and July 25) that have repeatedly disrupted patient care and contact tracing. WHO says more than 100 health care workers have been infected since the outbreak began. (AP)
Context (Aug 3) — outbreak formally confirmed as the largest ever recorded in DRC: Ahead of the Aug 4 AP figure above, WHO/UN OCHA confirmed the outbreak had surpassed DRC's 2018–2020 North Kivu epidemic (3,317 confirmed cases per UN News) to become the largest Ebola outbreak the country has ever recorded. Of the 49 affected health zones, 33 remain active with confirmed cases still being reported; Ituri Province accounts for 88% of all confirmed cases and 82.6% of deaths nationwide (UN OCHA/WHO, Aug 3). No new provinces, countries, or PHEIC status changes have been reported.
New (Aug 3) — DRC's largest Ebola treatment centre opens in Ituri: UN-backed health partners are inaugurating the country's largest Ebola treatment centre (100-bed capacity) this week, complementing a newly built Ebola transit centre at the Kigonze displacement camp on the outskirts of Bunia, set up with the US and International Medical Corps to speed identification and referral of suspected cases. WHO separately delivered 30 additional beds and 38 mattresses to Nizi (near Mongbwalu, Ituri), bringing that centre's capacity to 80 beds. WHO nonetheless says a substantial scale-up of response activity is still needed to get ahead of the outbreak, citing insecurity, displacement and cross-border movement among roughly 270,000 people sheltering in Ituri displacement sites — conditions WHO calls ideal for continued spread. Aid teams are also reporting the disease is causing stillbirths and premature deliveries among pregnant patients. (UN News / OCHA, Aug 3)
WHO (data through July 30) — 3,605 cases, 1,587 deaths, 49 of 140 health zones: WHO's latest situation report (DON-614) puts the outbreak at 3,605 confirmed cases and 1,587 deaths — a CFR of 44% — now spanning 49 of 140 health zones across the same five provinces (up from 47 on July 21). This WHO figure runs slightly ahead of the DRC Ministry's own July 31 press count (3,532 / 1,556 via Anadolu/Reuters), reflecting the ongoing reconciliation between national and WHO reporting streams described below. Including Uganda (20 cases, outbreak now closed) and France (1 case), the global cumulative stands at 3,626 cases and 1,589 deaths.
New — IHR Emergency Committee to reconvene August 18: WHO is preparing an updated Rapid Risk Assessment ahead of the next meeting of the IHR Emergency Committee on this outbreak, scheduled for August 18, 2026. The Committee will reassess whether the epidemic continues to meet the criteria for a Public Health Emergency of International Concern and may revise its temporary recommendations — the first substantive PHEIC review since the May 22 first-meeting recommendations.
Latest (DRC Ministry, July 31) — 3,532 cases, 1,556 deaths: The latest DRC Ministry figures put the outbreak at 3,532 confirmed cases and 1,556 deaths — a CFR of 44.1%, with 807 patients in isolation or hospital and 626 recovered. The death toll rose roughly 50% over the past week; Africa CDC says the sharp jump partly reflects a backlog of cases and deaths not previously confirmed or recorded. It remains the fastest-spreading Ebola epidemic ever documented. Confirmed spread still covers five provinces — Ituri (epicentre, ~90% of all cases), North Kivu, South Kivu, Haut-Uele and Tshopo (which includes the major city of Kisangani). WHO continues to warn the confirmed caseload understates true transmission by a factor of up to 4 given surveillance gaps in conflict-affected zones.
New (July 31) — Now the world's second-largest Ebola outbreak on record: With 3,532 confirmed cases, the outbreak has surpassed the DRC's own 2018–2020 North Kivu epidemic (~3,470 cases, Aug 2018–Jun 2020) to become the second-largest Ebola outbreak ever documented. Only the 2014–2016 West Africa epidemic (28,616 cases, 11,310 deaths across Guinea, Liberia and Sierra Leone) was larger. Less than three months in, the disease has killed five times as many people as previous outbreaks had by the same stage (Africa CDC). Carl Skau, acting head of the UN World Food Programme, called it "the fastest spreading Ebola epidemic that we have ever seen" and warned "the world needs to pay much more attention." Africa CDC now estimates it would take $1.4 billion to contain the outbreak — three times its earlier estimate.
Deaths are now mostly happening in the community (Africa CDC, July 30): Africa CDC Director-General Dr. Jean Kaseya reported that 63% of confirmed deaths in the last two weeks occurred outside treatment centres — largely due to the "unsafe handling of infected bodies" by residents, including touching highly infectious remains. This is a decisive containment failure: it means transmission is being driven by traditional burial practice and delayed care-seeking in communities that distrust the response, not by gaps inside clinical facilities. It compounds the July 15 hospital/ETC attack in Ituri's Nyakunde zone, which forced international partners to temporarily relocate and disrupted surveillance, contact tracing and supplies.
New (July 28) — Uganda declares its outbreak over: Uganda's Ministry of Health officially declared an end to its 2026 Ebola outbreak on July 28, closing a 20-case outbreak (18 recoveries, 2 deaths) with no sustained community spread. Notably, the declaration came ahead of WHO's standard 42-day countdown — Uganda's last patient was discharged July 16, placing it only ~12 days into the two-incubation-period window — with Health Minister Chris Baryomunsi citing evidence that transmission had been interrupted. Uganda is keeping its border with DRC closed and maintaining intensified border-district surveillance. Because transmission continues across the border in DRC, any new imported case would reopen the outbreak. (Incorporates team field note, Jul 29: Uganda declared Ebola-free early, before the full 42-day period; border surveillance continues.)
Health workers strike again (July 25): Staff at an Ebola treatment centre in the eastern DRC epicentre walked out again on Saturday, July 25, demanding unpaid wages — the second such stoppage this month. The walkout disrupted patient care at the heart of the outbreak and directly threatens the already-collapsing contact-tracing effort (reported by AP via Daily Sabah and DNYUZ).
Death toll milestone — 1,000 crossed in under 10 weeks (Africa CDC, July 23): At a health summit in Ghana on July 23, Africa CDC Director-General Dr. Jean Kaseya confirmed the toll had reached 1,031 — the outbreak crossed 1,000 deaths faster than any Ebola outbreak on record; the 2013–2016 West Africa epidemic took roughly eight months to reach the same toll. Kaseya's warning: "If we do not stop this outbreak today, it could become one of the worst Ebola outbreaks the world has ever documented… people are dying because we don't have vaccines, we don't have medicine, we don't have funding." (The toll passed 1,400 within days and reached 1,556 by the July 31 data — see above.)
Response capacity vs. transmission (context): Earlier this week WHO pointed to improved response capacity — contact follow-up nearing 80%, expanded laboratory and treatment capacity, and a slowing rate of increase in some health zones. But the latest national data (July 26) show the epidemic still growing, and any tentative "stabilization" signal is fragile and reversible, driven by surge support rather than an underlying break in transmission — it does not indicate the outbreak has peaked. Two localised bright spots hold: Kisangani has recorded no secondary cases — all five Tshopo cases remain importations from Ituri with no onward local spread detected — and in Kinshasa, contacts of the France-linked case remain under active follow-up with no confirmed capital transmission.
New (July 13) — Oxford begins Phase 1 vaccine trial (BD-Ebov): The University of Oxford has launched the world's first Phase 1 human trial of a candidate Bundibugyo vaccine — the ChAdOx1 BDBV vaccine, tested for safety and immunogenicity in 50 healthy adults aged 18–55 in Oxford. Follow-on studies are being prepared with the MRC/Uganda Virus Research Institute and LSHTM Uganda, pending regulatory approval. While a licensed, deployable BDBV vaccine remains far off, this is the first vaccine specifically targeting this strain to enter clinical testing — the most concrete step yet toward closing the countermeasure gap that defines this response.
Security incident (July 15) — Ebola treatment centre attacked in Bunia: WHO Director-General Tedros confirmed at the July 16 Geneva media briefing that an Ebola treatment centre in Bunia was attacked on Wednesday, July 15. Active armed conflict continues to hamper operations across Ituri and complicates efforts to reach affected communities. This compounds the health-worker strike over unpaid wages reported July 13–15 at the same facilities.
Community mistrust is undermining the response (ongoing): Local populations in Ituri continue to view the outbreak response with deep skepticism, and this mistrust is now a primary driver of continued transmission. Fear, rumours and hostility toward outside responders have produced attacks on Ebola treatment centres, resistance to burial teams, and suspected patients escaping isolation facilities; residents in Rwampara burned an ETC after tensions over the handling of a suspected Ebola death. Social-science teams (SSHAP, Mercy Corps, MSF) document a recurring "Ebola is a business" narrative and suspicion of responders' motives — the same dynamic that prolonged the 2018–2020 North Kivu outbreak. With no vaccine to offer and 80% of cases already off contact lists, rebuilding community trust — door-to-door engagement by local health workers and religious leaders — is as decisive to containment as any clinical countermeasure. (Team field note, Jul 28: "Locals continue to view outside assistance skeptically.")
Funding gap (July 16) — $400M+ shortfall: The joint WHO / Africa CDC continental preparedness and response plan still faces a funding gap of more than $400 million. UNICEF separately warned that only 25% of the funding required for its Ebola response is currently available. Tedros: "We urge donors to fill this gap… This is not charity. It's an investment in national security." Response capacity has nonetheless grown — treatment capacity now exceeds 800 beds, laboratory capacity has risen from 1 to 16 labs, contact follow-up rates have reached nearly 80%, and more than 21,000 community health workers are being trained.
Response crisis (July 13–15): Front-line health workers across Ituri — including epidemiological surveillance teams, case investigators, community outreach workers, burial teams, drivers and gravediggers — have begun striking over unpaid wages and bonuses dating to the outbreak's May 15 declaration. Staff obstructed the entrance to Bunia General Hospital and walked out at Rwampara General Hospital. Workers agreed to resume under a 72-hour government payment deadline; Health Minister Roger Kamba says authorities are verifying the payroll after unrelated names were added. A surveillance and burial-team stoppage at the epicenter directly threatens the already-collapsing contact-tracing effort.
Bright spot — Uganda outbreak declared over (July 28): Uganda discharged its last Ebola patient from the Mulago National Referral Isolation Centre on July 16 and, on July 28, its Ministry of Health officially declared the outbreak over — doing so ahead of WHO's full 42-day (two-incubation-period) countdown, which would otherwise have run to ~August 27. Uganda's outbreak totaled 20 confirmed cases, 18 recoveries and 2 deaths, of which 15 were imported from DRC and 5 locally acquired; no new case had been reported since June 21. Uganda is keeping its DRC border closed and maintaining intensified surveillance; WHO cautions that because transmission continues in DRC, a new imported case would reopen the outbreak.
No vaccine exists for this strain. ERVEBO (rVSV-ZEBOV) — used successfully in the 2018–2020 DRC outbreak — does not protect against Bundibugyo virus. WHO formally recommended against deploying it. There is zero approved countermeasure for BDBV.

1. Bundibugyo is a rare, poorly understood strain. Only the third known human outbreak of this ebolavirus species in history. The prior two were in Uganda (2007–2008, 149 cases) and DRC (2012, 57 cases). Genomic sequencing published May 2026 confirmed this is a new spillover from an unknown animal reservoir — not descended from either prior outbreak.

2. Contact tracing has effectively failed. WHO's own emergencies director confirmed that 80% of newly confirmed patients have no link to any known contact list. In a vaccine-era outbreak, imperfect tracing can be compensated by ring vaccination. Here, no such ring exists.

3. The capital is on alert. DRC has banned public gatherings in Kinshasa (17 million people) and three other provinces as a precaution. An earlier suspected Kinshasa case tested negative on confirmatory testing (WHO, May 17), and no sustained transmission has been confirmed in the capital as of WHO's July 9 report. But just 1km across the Congo River sits Brazzaville — Republic of Congo's capital, equally connected to global air networks. Sustained transmission in either city would fundamentally change the outbreak's geography.

4. The outbreak has already left Africa. A response worker who had been in DRC traveled to France in late June and tested positive — the first confirmed case outside Africa in this outbreak. International importation chains have begun.

5. Estimated true scale is up to 4× larger. WHO estimates the confirmed figure of ~3,532 understates the real outbreak size by a factor of up to four, due to the surveillance collapse in conflict-affected zones of Ituri Province.

WHO's 100-day retrospective (Aug 24): contact tracing of registered contacts rose from 9% in week one to 84% as of Aug 18; Africa CDC's Yap Boum (Aug 22) separately put the actual tracing rate at just 16% of the ~100,000 contacts that should have been identified given case volume (vs. 95% target) — only 20% of health alerts originate from within affected communities. 97% of deaths reported Aug 17 occurred in the community rather than a treatment centre. DRC Health Minister Roger Kamba confirmed no cases in Kinshasa (Aug 19) and flagged Tshopo/Kisangani's river-road-air corridor to the capital as a particular concern, with river-route screening stepped up. More than 63% of deaths occurring in communities rather than treatment centres or hospitals (Africa CDC's Kaseya, Aug 16). Africa CDC is pushing a village-based response that would retrospectively reconstruct the undocumented Feb–May pre-declaration period via community recall; WHO's Chikwe Ihekweazu says the virus may have circulated 2–3 months before formal detection (Aug 16). Virus has reached at least 5 of Ituri's 69 IDP camps (19 infected, 5 dead — UNHCR, Aug 6–7). Child deaths have passed 300 (UN News, Aug 7). Genomic study (Nature Medicine, Aug 13) finds the outbreak began with a new, independent animal-to-human spillover distinct from the 2007/2012 Bundibugyo lineages. WHO named the Central African Republic, alongside Uganda and South Sudan, as countries at elevated risk of imported cases (Aug 19) — CAR is a new addition to the watch list. Mercy Corps flags cases ~35km from the South Sudan border — no confirmed South Sudan cases yet. Ten further provinces incl. Kinshasa designated high-risk for preparedness.

Two Americans Infected — Second Case Evacuated to Germany

First case (confirmed, named): Dr. Peter Stafford, a missionary surgeon with Serge (Pennsylvania-based Christian missions organization). Exposed during surgery at Nyankunde Hospital, Bunia. Evacuated to Charité University Hospital, Berlin. Recovered and returned to the U.S. in early June 2026.

Second case (confirmed July 10, medevac July 13): Described by CDC as "a U.S. citizen working for a humanitarian organization in DRC." Per ECDC and CDC updates, the patient tested positive for Bundibugyo virus on July 10 and was medically evacuated to Germany on July 13, 2026. Identity, employing organization and current clinical condition remain undisclosed. CDC is working with the patient's employer, other federal agencies, and DRC partners to identify high-risk contacts and prevent onward transmission.

Update (July 15): The second US case is now confirmed and evacuated — the third medical evacuation to Europe in this outbreak (after Berlin for the first US case and France's own imported case). This marks a second active importation chain into Germany. No secondary transmission from any evacuated case has been reported. Clinical outcome pending.

ERVEBO Does Not Protect Against Bundibugyo

This is the critical structural difference from every prior DRC outbreak since 2018. The CDC's Health Alert Network (HAN-00530) states explicitly:

"There is currently no FDA-licensed or authorized vaccine to protect against Bundibugyo virus infection. The Ebola vaccine licensed in the United States (ERVEBO®) is indicated for preventing Ebola disease due to a different species... and based on studies in animals, this vaccine is not expected to protect against Bundibugyo virus."

WHO advisors formally recommended against deploying ERVEBO in this outbreak in May 2026. The Mvabea/Zabdeno regimen (Janssen) also targets only the Zaire strain.

New (Aug 28) — DRC begins actually administering ERVEBO, under compassionate use: Congo started vaccinating on Thursday, August 27, officially launching the campaign in Kisangani (Tshopo province) under Health Minister Roger Kamba. Health workers and frontline responders are first, alongside contacts of confirmed patients. The campaign is expected to cover 14 health zones across Tshopo, Bas-Uele and Haut-Uele; DRC's state news agency reports more than 50,000 doses received of the 70,000 approved by the ICG on Aug 20. This is the first time in this outbreak that vaccine has moved from allocation and shipment to arms. The structural caveat above is unchanged and central: Ervebo is licensed for Zaire ebolavirus, not Bundibugyo, so it is being deployed here under a compassionate-use program rather than an approved indication, and human efficacy against BDBV remains unproven. Africa CDC's Placide Mbala Kingebeni said effectiveness data will be collected during the campaign itself — meaning the rollout doubles as an observational evidence-generation exercise alongside the separate 20,000-dose Phase 3 randomized trial. (Associated Press via PBS NewsHour / Washington Post, Aug 27)
New (Aug 7) — ERVEBO fast-tracked into Phase 3 ring trial against Bundibugyo: WHO's Technical Advisory Group recommended the licensed ERVEBO (rVSV-ZEBOV) vaccine be prioritized for a Phase 3 ring trial in DRC against Bundibugyo virus, reversing its May 2026 recommendation against deployment. Preclinical data showed 3 of 4 vaccinated non-human primates survived Bundibugyo challenge and a ferret study found 100% protection with the research-grade formulation. Gavi's 500,000-dose global stockpile will supply the trial, with doses already in-country — a far larger-scale vaccine option than the 50-participant Oxford Phase 1 study below, though human efficacy against this strain remains unproven. (Al Jazeera, Gavi, Aug 7)
First BDBV vaccine enters human testing (July 13, 2026): The University of Oxford has launched its Phase 1 BD-Ebov trial of the ChAdOx1 BDBV vaccine in 50 healthy adults (18–55) — the first vaccine specifically targeting this strain to reach clinical testing, with follow-on studies planned in Uganda (MRC/UVRI, LSHTM). Phase 1 assesses only safety and immunogenicity in a small cohort, so any licensed, deployable product remains many months to years away and will not affect the current outbreak's trajectory. It is nonetheless the most concrete long-term step yet toward closing the countermeasure gap.

Treatment Trial — Only Active Countermeasure

The PARTNERS trial (Platform Adaptive Randomised Trial for New and Repurposed Filovirus TreatmentS), co-sponsored by WHO, INRB, ALIMA, and MSF, began enrolling patients on July 2, 2026 in Ituri Province. It tests MBP134 (Mapp Biopharmaceutical monoclonal antibody cocktail, originally developed specifically for BDBV) and remdesivir (Gilead antiviral, widely used for COVID-19), versus optimized supportive care. This is the most important variable to watch: early efficacy signals in August could materially change the outbreak trajectory.

New — post-exposure prophylaxis: On July 14, 2026, INRB launched EBO-PEP, the first trial to assess post-exposure prophylaxis with the antiviral obeldesivir in high-risk contacts across DRC and Uganda. If effective, a prophylactic taken after exposure could partially substitute for the ring-vaccination strategy that is unavailable against BDBV — a potentially significant tool given that 80% of new cases fall outside known contact lists.

Trajectory A
20%
Controlled Containment
Treatment trial turns the tide · Outbreak over by Dec 2026
▸ expand
  • MBP134 shows rapid efficacy — CFR drops below 10% within 45 days of deployment
  • Emergency vaccine candidate fast-tracked under compassionate use by Aug 2026
  • International surge (MSF, WHO, USAID) restores contact tracing in Bunia
  • Kinshasa transmission stays limited — ring containment holds
  • Peak ~2,500 cases · Declared over Nov–Dec 2026

Requires: treatment trial results within ~30 days AND humanitarian access in armed zones

Trajectory B — Most Likely
50%
Prolonged Regional Epidemic
6–12 months · 5,000–15,000 total cases
▸ collapse
  • Contact tracing never recovers — 80% case gap is structural, not temporary
  • Kinshasa becomes a sustained transmission zone by Aug–Sep 2026
  • Cases spread to South Sudan, Burundi, Rwanda via land corridors
  • Treatment trial reduces CFR but cannot replace vaccines at population scale
  • Multiple international importations following France — Gulf states, EU hubs

Driver: Armed conflict + urban spread + no vaccine = containment requires paradigm shift in international response

Trajectory C
25%
Continental Escalation
Exceeds 2014–2016 West Africa scale
▸ expand
  • Kinshasa–Brazzaville corridor (capitals, 1km apart) becomes bi-national epicenter
  • Lagos, Nairobi, Johannesburg report community transmission via air hubs
  • Treatment trial results delayed or inconclusive
  • Conflict escalation forces evacuation of response teams in eastern DRC
  • WHO elevates to "pandemic emergency" under revised IHR framework
  • 20,000–50,000 total cases — comparable to 2014–2016

Trigger: Kinshasa sustained transmission + one hub city importation. Once Lagos or Nairobi sees community spread, probability cascades rapidly.

Trajectory D
5%
Global Health Catastrophe
Multi-continent sustained transmission
▸ expand
  • Concurrent crises prevent any coherent DRC response
  • Sustained community transmission chains established in Western countries
  • All vaccine candidates fail; MBP134 shows limited efficacy
  • Requires COVID-19-level global mobilization to contain

Note: Ebola's fluid-contact transmission mechanism makes this significantly less probable than with respiratory pathogens. Requires simultaneous failure across multiple containment systems.

Why Kinshasa Is the Variable to Watch

Status (as of Jul 19): No sustained transmission has been confirmed in Kinshasa. A single earlier suspected case in the capital tested negative on confirmatory testing (WHO, May 17). As a precaution, DRC authorities have banned public gatherings in Kinshasa and three other provinces. The concern is structural rather than realized: Kinshasa sits directly across the Congo River from Brazzaville — the Republic of Congo's capital — separated by approximately 1 kilometer of water. Both cities are major regional air hubs, collectively connected to Lagos, Nairobi, Johannesburg, Paris, Brussels, and Doha.

In prior DRC outbreaks, geographic containment was achievable because outbreaks remained in remote rural areas. The 2018–2020 North Kivu outbreak (same geography, Zaire strain) reached the provincial city of Butembo but never Kinshasa. The current outbreak has now crossed that threshold.

Watch item — Kisangani is the river bridgehead. Tshopo province now reports 5 cases (4 deaths) across 3 of 23 health zones, seeded when a pregnant woman who died in Bunia on June 27 was transported to Kisangani, where her body tested positive on June 30. Investigators assess both the Tshopo and Haut-Uele clusters as importations from Niania in Ituri — human movement, not independent spillover. Kisangani sits ~500 km west of the epicentre on the Congo River, the main transport corridor linking eastern DRC to Kinshasa. This is the mechanism by which the outbreak would reach the capital, and it is now active.
New (Aug 6) — the corridor produced its first real test case. A 255-passenger boat that left Kisangani travelled the full ~1,700km river route toward Kinshasa before being intercepted and quarantined just 65km from the capital, after a passenger who disembarked upriver in Mongala Province died July 25 with Ebola-like symptoms. DRC officials confirmed 5 deaths tied to the journey; the first 7 onboard passengers tested negative on Aug 7, but the 21-day incubation window is still open. Kinshasa authorities are reinforcing surveillance capacity at the Maluku river entry point as a result.
The Kinshasa–Brazzaville scenario is the single most dangerous escalation pathway. Both cities combined have a population exceeding 20 million people and some of the highest urban population densities in sub-Saharan Africa. Sustained community transmission in either city would be extraordinarily difficult to contain without a vaccine ring strategy.

This Is the Exact Scenario VitaAlert Is Built For

The three critical intelligence gaps this outbreak exposes — offline field reporting in conflict zones, AI risk scoring when 80% of cases are off contact lists, and cross-border corridor monitoring — are precisely the problems the VitaAlert platform is designed to solve.

This is not a theoretical use case. The outbreak is live, the surveillance failure is documented by WHO, and the gaps are causing preventable deaths. The case for epidemic intelligence infrastructure in emerging markets has rarely been more visibly demonstrated.

Intelligence briefs like this one will be published daily by the VitaAlert team during the active PHEIC. Team members can submit comments and corrections via the feedback panel. Reports are AI-verified against primary CDC, WHO, ECDC, and peer-reviewed sources before publication.
