WHO Africa (download report) On 4 September 2025, the Ministry of Health of the Democratic Republic of the Congo (DRC) declared an outbreak of Ebola Virus Disease in Bulape Health Zone, Kasai Province, following laboratory confirmation by real-time polymerase chain reaction (RT-PCR) and GeneXpert assays at the National Institute of Biomedical Research (INRB) in the capital Kinshasa. This is the 16th outbreak of Ebola virus disease in the Democratic Republic of the Congo.
The presumptive index case, a 34-year-old pregnant woman with 34 weeks of gestation from Tshitekeshi, Bulape Health Area, Bulape Health Zone, reportedly developed symptoms on 10 August 2025 and was admitted in labour to the Obstetrics and Gyneacology ward at a local hospital on 20 August 2025, with high-grade fever and acute onset of bloody watery diarrhoea. She died on 26 August 2025 while on admission and was subsequently buried in the community without adherence to safe and dignified burial practices. No sample was collected prior to burial.
