BUNDIBUGYO VIRUS DISEASE OUTBREAK Democratic Republic of the Congo | Kenya | Nigeria - Weekly External Situation Report 25, Data as of 7 November 2026

The Bundibugyo virus disease (BVD) outbreak in the Democratic Republic of the Congo continues to spread at a high and sustained level, with no signs of decreasing. During the latest reporting period, nearly 390 confirmed cases were added, and the national seven-day average remains between 65 and 67 cases per day. Nord-Kivu has contributed almost as many cases as Ituri, accounting for the entire increase observed over the past 21 days.

Contact follow-up efforts have reached their lowest level in weeks at the end of the period. Importation events in Kenya and Nigeria remain contained, with no new cases reported in Kenya since October 19th, and no secondary cases identified in Nigeria, where contact monitoring is expected to end on November 13th. However, insecurity, health-worker strikes, and the suspension of response activities in certain areas of the Congo pose significant challenges to surveillance and response operations.

As of November 7th, 2026, the BVD outbreak has affected 67 health zones and 247 health areas across eight provinces in the Congo, with a cumulative total of 10,920 confirmed cases and 5,323 deaths (crude case fatality ratio of 48.7%). Transmission remains highly heterogeneous across affected areas, with Ituri accounting for the largest proportion of cumulative confirmed cases (69.7%), while Nord-Kivu (24.7% of cumulative cases, CFR 54.8%) saw almost as many cases reported since the previous report as Ituri (47.2%). Lower transmission levels persist in Haut-Uele, Tshopo, and Nord-Ubangi.
