Kasai: Health authorities in the Democratic Republic of the Congo have declared an outbreak of Ebola virus disease in Kasai Province where 28 suspected cases and 15 deaths, including four health workers, have been reported as of 4 September 2025.

According to Emirates News Agency, a national Rapid Response Team joined by World Health Organization (WHO) experts in epidemiology, infection prevention and control, laboratory, and case management has been deployed to Kasai Province. Their mission is to rapidly strengthen disease surveillance, treatment, and infection prevention and control in health facilities. Additionally, provincial risk communication experts have been deployed to reach communities and help them understand how to protect themselves.

WHO is also delivering two tonnes of supplies, including personal protective equipment, mobile laboratory equipment, and medical supplies. Dr. Mohamed Janabi, WHO Regional Director for Africa, stated, "We're acting with determination to rapidly halt the spread of the virus and protect communities." The WHO is working closely with health authorities to quickly scale up key response measures to end the outbreak.

Case numbers are likely to increase as the transmission is ongoing. Response teams and local teams are working to find people who may be infected and need to receive care, ensuring everyone is protected as quickly as possible. The country has a stockpile of treatments and 2000 doses of the Ervebo Ebola vaccine, effective against this type of Ebola, already prepositioned in Kinshasa. These will be quickly moved to Kasai to vaccinate contacts and frontline health workers.
