On 4 September 2025, the Ministry of Health of the Democratic Republic of the Congo (DRC) declared an outbreak of Ebola Virus Disease (EVD) in Kasai Province, following confirmation of Zaire ebolavirus by the National Institute of Biomedical Research (INRB) in Bulape and Mweka Health Zones. As of 19... September, there have been 48 total cases (38 confirmed, 10 probable) with 31 deaths (21 confirmed, 10 probable) and a CFR of 64.5%. Among laboratory confirmed cases, 16 deaths were recorded (CFR: 45.7%). Four deaths occurred among health workers, underscoring the risk of nosocomial transmission. Most cases (39.7%) are among adults aged 20 years and above, in a densely populated, remote, and under-resourced area.
The outbreak is driven by multiple risk factors, including transmission in health facilities with limited infection prevention and control (IPC) measures and personal protective equipment (PPE), incomplete contact tracing, delayed detection, and unsafe burial practices. High population mobility between Bulape and Tshikapa, reliance on traditional healers, and the concurrent mpox outbreak are further straining the fragile health system and increasing the risk of geographic spread.

The number of reported cases of Ebola virus disease (EVD) consistently declined in recent weeks, with 14 new confirmed cases reported in North Kivu and Ituri provinces during the epidemiological week of 30 September through 6 October. At peak transmission in April 2019, there were 126 cases in the w...eek. Although the decline in case incidence is encouraging, it must be interpreted with caution as the situation remains highly contingent upon the level of access and security.
