WHO DECLARES EBOLA OUTBREAK IN CONGO AND UGANDA A PUBLIC HEALTH EMERGENCY OF INTERNATIONAL CONCERN

The World Health Organization declared the Ebola outbreak in the Democratic Republic of Congo and Uganda a public health emergency of international concern on May 17, 2026, as the epidemic caused by the Bundibugyo virus strain spread across multiple health zones. As of May 19, more than 500 suspected cases and 130 deaths had been reported, with 30 laboratory-confirmed cases in DRC and two confirmed cases in Uganda's capital, Kampala, according to WHO.

The outbreak is caused by the Bundibugyo virus, a species of Ebola for which no approved vaccines or therapeutic treatments currently exist, complicating the international response. The case fatality rate for the Bundibugyo strain is estimated at between 25 and 40 percent, WHO said. Eight laboratory-confirmed cases were recorded in Ituri Province across at least three health zones — including Bunia, Rwampara, and Mongbwalu — with cross-border spread to Uganda confirmed among travelers from DRC.

In response to the emergency declaration, WHO deployed rapid response teams, delivered medical supplies, and established safe treatment centers in affected areas. The U.S. Centers for Disease Control and Prevention separately restricted travel from DRC. Cross-border preparedness measures are being strengthened as health authorities in Uganda and neighboring countries are placed on high alert, with WHO coordinating surveillance, case management, and community engagement across both countries.
