WHO Declares Ebola Outbreak in DRC and Uganda a Public Health Emergency

The World Health Organization (WHO) has declared the Ebola outbreak in the Democratic Republic of the Congo (DRC) and Uganda a public health emergency of international concern (PHEIC). The outbreak, caused by the rare Bundibugyo strain of the Ebola virus, has resulted in numerous cases and fatalities in both countries.

As of May 17, 2026, the DRC has reported 10 confirmed cases, 336 suspected cases, and 88 deaths, primarily in the Ituri Province. Uganda has confirmed two cases, including one death, in individuals who had traveled from the DRC.

The Bundibugyo strain is less common than other Ebola virus strains and lacks approved treatments or vaccines, complicating containment efforts. The outbreak's rapid escalation and cross-border spread have raised concerns among international health authorities.

In response, the U.S. Centers for Disease Control and Prevention (CDC) has implemented enhanced travel screening and entry restrictions to prevent the virus from entering the United States. Additionally, an American doctor working in the DRC has tested positive for the virus. The CDC is coordinating the safe evacuation of the infected individual and six other Americans who may have been exposed.

The WHO continues to monitor the situation closely and is working with international partners to support response operations, including surveillance, laboratory diagnostics, and infection prevention and control measures.
