Ebola Bundibugyo virus disease outbreak: Democratic Republic of the Congo | Kenya | Nigeria Weekly External Situation Report 25, Data as of 7 November 2026

Please refer to the attached file. Event description The Bundibugyo virus disease (BVD) outbreak in the Democratic Republic of the Congo continues at a high, sustained level of transmission, with no sign of decline: close to 390 confirmed cases were added during the reporting period and the national seven-day average has stayed between 65 and 67 cases per day. Nord-Kivu now contributes almost as many cases as Ituri and accounts for the entire increase observed over the last 21 days, while contact follow-up fell to its lowest level in weeks at the end of the period. The importation events in Kenya and Nigeria remain contained: no new case has been reported in Kenya since 19 October, six of the seven surviving patients have been discharged and the last contacts will complete monitoring on 11 November, while no secondary case has been identified in Nigeria, where contact monitoring is expected to end on 13 November. In the Democratic Republic of the Congo, insecurity in Beni health zone in North Kivu and Bafwasende in Tshopo, health-worker strikes in Bas-Uélé and Tshopo and the continued suspension of response activities in Bafwasende constrain surveillance and response operations. As of 7 November 2026, the BVD outbreak in the Democratic Republic of the Congo has affected 67 health zones and 247 health areas across eight provinces; no new health zone was affected during the reporting period. Since External Situation Report #24, an additional 388 confirmed cases and 197 confirmed deaths have been reported, bringing the cumulative total to 10 920 confirmed cases, including 5 323 confirmed deaths [crude case fatality ratio (CFR) 48. 7%]. Transmission remains highly heterogeneous across affected areas. Ituri continues to account for the largest proportion of cumulative confirmed cases (69. 7%), although its relative contribution is declining, while Nord-Kivu (24. 7% of cumulative cases; CFR 54. 8%) accounted for 46. 1% of the cases reported since the previous report, almost as many as Ituri (47. 2%). Transmission persists at lower levels in Haut-Uélé (4. 9% of new cases), Tshopo and Nord-Ubangi. National daily incidence rose steadily from May to its highest levels in late July and mid-August, declined through late September and has fluctuated at a high plateau since early October. The seven-day moving average ranged between 65 and 67 confirmed cases per day during the reporting period (64. 7 on 7 November, compared with 67. 0 on 1 November and a late-October high of 76), still well below the mid-August peak of 94. Provincial trends continue to diverge. Ituri continues its slow decline from the late-July peak (seven-day average of 29 cases per day on 7 November, down from 31 on 1 November and 38 on 19 October), while Nord-Kivu has risen to 31 cases per day (up from 30 on 1 November and 26 on 19 October) and exceeded Ituri on several days of the period. Haut-Uélé remains stable at three to four cases per day, Tshopo reports sporadic cases (last case on 5 November) and Nord-Ubangi reported three further cases in Yakoma and Wapinda. Bas-Uélé, Sud-Kivu and Sud-Ubangi have reported no case in the last 21 days (Figures 1 and 2).
