Bundibugyo Ebola Outbreak Expands Across DRC and Uganda, WHO Warns

The WHO reports a rapidly evolving Bundibugyo virus disease outbreak in the Democratic Republic of the Congo and Uganda, with 906 suspected cases and 223 deaths in DRC and 134 confirmed cases (nine in Uganda) with 18 deaths as of 29 May 2026. Transmission remains concentrated in Ituri, North Kivu and South Kivu, and cross-border spread, insecurity, and gaps in isolation and follow-up complicate response. A U.S. physician treating patients in DRC tested positive and is being treated in Germany. Public health measures include rapid response teams, enhanced surveillance, lab confirmation, infection prevention and control, safe treatment centers, and community engagement; there are no approved vaccines or specific treatments. WHO assessed national risk as very high in DRC, high regionally, and low globally, and urged coordinated outbreak control and sustained surveillance with no travel restrictions for now.
