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

The Ebola Bundibugyo Virus outbreak in the Democratic Republic of the Congo continues to expand, affecting 65 health zones across seven provinces since its inception. Transmission is reported to be highly heterogeneous in these regions. Since the last External Situation Report #21, an additional 463 confirmed cases and 233 confirmed deaths have been reported, raising the cumulative total of cases to 9066, with 4381 deaths (48.3% crude case fatality ratio).

Ituri remains the primary focus of the outbreak, accounting for 73.8% of all confirmed cases. While transmission is still significant in Nord-Kivu and Haut-Uélé, the epidemic now exhibits a more fragmented pattern, with periods of decline and subsequent rebounds. This suggests a shifting and geographically fragmented epidemic rather than sustained contraction.
