Bundibugyo Ebola outbreak reaches 378 confirmed cases, the largest on record for this virus

CDC modeling warns that without faster patient isolation, the cross-border outbreak in the DRC and Uganda could grow as large as the 2014–2016 West Africa epidemic.

An Ebola outbreak caused by the Bundibugyo virus has spread across the Democratic Republic of the Congo and into Uganda, reaching 378 confirmed cases and 63 confirmed deaths as of June 2, 2026 — already the largest outbreak on record for this Ebola species, according to a modeling report published by the U.S. Centers for Disease Control and Prevention.

The CDC’s Morbidity and Mortality Weekly Report states it plainly: “As of June 2, 2026, a total of 378 confirmed cases (363 in DRC and 15 in Uganda) and 63 confirmed deaths (62 in DRC and one in Uganda) have been recorded.” The vast majority of illness and death remains in the DRC, where this is the country’s 17th declared Ebola outbreak. Those figures put the case-fatality rate among confirmed cases at roughly 17 percent, though both the numerator and the denominator are likely to shift as suspected cases are confirmed or discarded.
