EBOLA BUNDIBUGYO VIRUS DISEASE OUTBREAK Democratic Republic of the Congo | Uganda Weekly External Situation Report 15, Data as of 23 August 2026

Event description
More than three months into the response, the Bundibugyo virus disease (BVD) outbreak in the Democratic Republic of the Congo remains characterized by sustained transmission, high mortality and continued geographic expansion. The epidemiological picture is increasingly heterogeneous, with persistent transmission in established hotspots in Ituri, intensifying transmission in parts of Nord-Kivu and Haut-Uélé, and continued geographic expansion through the emergence of cases in previously unaffected health zones. Since External Situation Report #14, a total of 563 new confirmed cases and 302 confirmed deaths have been reported, bringing the cumulative total to 5 584 confirmed cases, including 2 680 deaths. The number of affected health zones has increased from 55 to 57 across six provinces, with Viadana in Bas-Uélé and Mutwanga in Nord-Kivu being the most recently affected health zones.
