Congo Ebola Outbreak Above 5,000 Cases Gets 70,000 Ervebo Doses
World Health Organization and partners said Thursday that Congo will receive 70,000 doses of the Ervebo Ebola vaccine to help contain a Bundibugyo-virus outbreak that has surpassed 5,000 cases.[1]
Twenty thousand doses are earmarked for a Phase 3 clinical trial and 50,000 are reserved for front-line and health workers, with shipments to be released after Congo requests them.[1] WHO says Ervebo is licensed for Zaire Ebola, not for Bundibugyo, but early lab and animal data suggest it may offer some protection.[1]
Congo's health ministry reported 5,021 cases and 2,378 deaths as of Sunday, August 16, 2026.[2] By Thursday the outbreak was reported at 5,208 confirmed cases and 2,476 deaths, with an overall case fatality rate near 47.5%.[1] The epidemic is caused by the Bundibugyo virus and is the largest Bundibugyo outbreak ever and the deadliest Ebola outbreak in Congo's history.[3] Health officials say the first detected patient developed symptoms in late April, cases clustered around Mongbwalu, and Congo formally declared the outbreak on May 15.[3]
Earlier reporting stressed that vaccines and antibody treatments developed for Zaire Ebola are not approved for Bundibugyo, leaving patients reliant on supportive care while trials proceed.[3] The new Ervebo allocation, which WHO Director-General Tedros Adhanom Ghebreyesus called "an important example of global solidarity in action," signals a shift toward testing a vaccine-driven response.[1] Officials warn the epidemic remains far from controlled and the risk of further national and international spread is high.[2] Response teams also face insecurity and mistrust on the ground; residents in Aru territory attacked a health team on Monday, August 17, burning an ambulance and damaging vehicles.[2]

📌 Key Facts
- As of Thursday, August 20, 2026, the outbreak has 5,208 confirmed cases and 2,476 deaths, with an overall case fatality rate of 47.5% and rates up to about 70% in North Kivu (5,208 confirmed cases).
- Congo's Ministry of Health reported the outbreak reached the 5,000-case threshold with 5,021 cases and 2,378 deaths as of Sunday, August 16, 2026 (Congo's Ministry of Health).
- The outbreak is caused by the Bundibugyo virus — this is the largest Bundibugyo-virus Ebola outbreak ever and the deadliest Ebola outbreak in Congo's history (Bundibugyo virus).
- WHO and partners said Congo will receive 70,000 doses of the Ervebo Ebola vaccine — 20,000 doses earmarked for a Phase 3 clinical trial and 50,000 reserved for front-line and health workers — with doses to be released after a request from Congo’s government (70,000 doses of the Ervebo Ebola vaccine).
- WHO says Ervebo is licensed for Ebola virus but not for Bundibugyo; early laboratory and animal data suggest it may provide some protection, while vaccines and antibody treatments developed for Zaire Ebola are not approved for Bundibugyo and patients currently rely on supportive care as clinical trials proceed (Ervebo).
- Officials say the outbreak is spreading faster than past epidemics — about three times faster than the 2014–2016 West Africa epidemic from the first detected case — and WHO Director‑General Tedros Adhanom Ghebreyesus warned on Tuesday, August 18, 2026, that the epidemic is 'far from being under control' with high risk of further national and international spread (three times faster than the 2014–2016 West Africa epidemic).
- Transmission is concentrated in remote and insecure areas where insecurity, displacement and intense population movements fuel spread; on Monday, August 17, 2026, residents in Aru territory in Ituri province attacked a health team, burning an ambulance and damaging other vehicles (Aru territory in Ituri province).
- The epidemic has crossed borders — transmission reached Uganda (which has since stopped transmission) and a confirmed Bundibugyo case was reported in France in June 2026 in a doctor who later recovered (Uganda).
