WHO outbreak report: Ebola disease caused by Bundibugyo virus - Democratic Republic of the Congo

What WHO reported

Since the last Disease Outbreak News was published on 28 August 2026, the Bundibugyo virus outbreak in the Democratic Republic of the Congo has expanded to one additional health zone, Kayna, in North Kivu. This increase brings the total number of affected health zones to 61 across six out of 26 provinces of the country: Bas-Uélé, Haut-Uélé, Ituri, North Kivu, South Kivu, and Tshopo. As of 7 September 2026, the Democratic Republic of the Congo has reported 6757 confirmed cases, including 3267 deaths, resulting in a crude case fatality ratio (CFR) of 48.3%. The transmission dynamics remain variable across affected locations, with evidence of ongoing geographical expansion and sustained increase in cases in some health zones. The continuously high CFR highlights the seriousness of the disease and persistent challenges in timely case detection, access to early and adequate patient care, and effective interruption of transmission. Delayed detection of cases continues to increase the risk of further spread within households, communities, and healthcare settings.
