Ebola
An outbreak of Ebola disease caused by the Bundibugyo virus is currently underway in eastern Democratic Republic of Congo, with cases also reported in Uganda. The World Health Organization declared this outbreak a public health emergency of international concern in May 2026, and the Africa Centres for Disease Control and Prevention (Africa CDC) subsequently declared it a Public Health Emergency of Continental Security on 18 May 2026. Bundibugyo is a rare cause of Ebola, related to the more familiar Zaire Ebola strain responsible for most previous outbreaks. There is currently no readily available rapid diagnostic test, no treatment, and no vaccine for this strain, meaning that public health containment measures remain the only line of defence.
While the outbreak is concentrated in the DRC and Uganda, imported cases of Ebola in South Africa are a possibility and there is a need to prepare now. CAPRISA is actively engaged in the response to this outbreak: CAPRISA Director Prof Salim S. Abdool Karim chairs the Africa CDC Emergency Consultative Group, whose recommendations underpinned the continental emergency declaration, and serves as Special Advisor to the Director-General of the World Health Organization. CAPRISA will also be collating data to inform the regional response. The resources here provide further information on the virus, the current situation, and the response.
