Event description
The Bundibugyo virus disease (BVD) outbreak in the Democratic Republic of the Congo continues to evolve, 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 the continued emergence of cases in previously unaffected health zones. Since External Situation Report #15, a further 516 confirmed cases and 270 confirmed deaths have been reported, bringing the cumulative total to 6100 confirmed cases, including 2950 deaths (CFR 48.4%), as of 30 August 2026. The number of affected health zones has increased from 57 to 60 across six provinces, with Biena and Manguredjipa in Nord-Kivu and Ganga in Bas-Uélé newly affected since the previous update. Ituri remains the epicentre, accounting for 82.2% of cumulative confirmed cases, although continued expansion in Nord-Kivu and Bas-Uélé underscores the increasingly dispersed geographic pattern of the outbreak.
