Emergencies and Outbreaks News

On 4 September 2025, the Democratic Republic of the Congo declared an outbreak of Ebola virus disease in the country’s Kasai Province where a cluster of cases and deaths had been reported. Samples tested on 3 September at the country’s National Institute of Biomedical Research in the capital Kinshasa confirmed the cause of the illness and fatalities as Ebola Zaire caused by Ebola virus disease.

The Weekly Bulletin focuses on public health emergencies occurring in the WHO African Region. Each week, a brief description, followed by public health measures implemented and an interpretation of the situation is provided for a few selected events.

A table is provided at the end of the bulletin with information on all new and ongoing public health events currently being monitored in the region, as well as recent events that have largely been controlled and thus closed.
