BUNDIBUGYO VIRUS DISEASE OUTBREAK Democratic Republic of the Congo | Kenya | Nigeria - Weekly External Situation Report 24, Data as of 1 November 2026

The Bundibugyo virus disease (BVD) outbreak in the Democratic Republic of the Congo has surpassed 10,000 confirmed cases as of November 1, 2026, with transmission remaining at a high and sustained level. The outbreak is increasingly driven by Nord-Kivu, while Ituri remains the largest contributor. Importation events in Kenya and Nigeria have so far remained contained, with no new cases reported in Kenya since October 19 and all secondary cases occurring among contacts already in quarantine.

However, one new death was reported in Kenya, bringing the total death toll to two. Insecurity, health-worker strikes, and suspension of response activities in certain health zones continue to hinder surveillance and response operations in the Democratic Republic of the Congo. As of November 1, 2026, the outbreak has affected 67 health zones across eight provinces in the country, with Yakoma Health Zone in Nord-Ubangi Province recently added to the list.

The cumulative total now stands at 10,532 confirmed cases, including 5,126 confirmed deaths, resulting in a crude case fatality ratio (CFR) of 48.7%. Transmission remains highly heterogeneous across affected areas, with Ituri accounting for the largest proportion of cumulative confirmed cases (70.6%), although its relative contribution is declining.

Nord-Kivu accounts for 23.9% of cumulative cases and 60.0% of cases reported on November 1, with transmission persisting at lower levels in Haut-Uélé and Tshopo.
