Ebola Bundibugyo outbreak in DRC/Uganda spreads rapidly amid response challenges
Consensus Summary
The Ebola Bundibugyo virus outbreak in the Democratic Republic of Congo and Uganda has rapidly escalated since mid-May 2026, with 676 confirmed cases and 136 deaths in DRC alone as of mid-June. The virus, which lacks a vaccine or approved treatment, has spread to 25 health zones, primarily in Ituri and North Kivu provinces, with limited progress in contact tracing (64% completion) and community trust. Uganda has contained its smaller outbreak (19 cases, 2 deaths) through aggressive contact tracing. International response efforts face obstacles including armed conflict, misinformation, and supply shortages, with Africa CDC estimating $518 million is needed to control the outbreak. Experts warn the situation could worsen, with modeling suggesting potential to surpass the 2014-16 West Africa outbreak if unchecked. Frontline workers, including healthcare staff and aid responders, are at high risk, with 34 infections and 7 deaths reported. The WHO has declared the outbreak a Public Health Emergency of International Concern, while travel restrictions imposed by 22 countries have hindered response efforts.
