WHO Declares Bundibugyo Ebola Symptoms Emergency in Congo, Uganda
The World Health Organization has declared the Ebola disease outbreak caused by Bundibugyo virus in the Democratic Republic of the Congo and Uganda a public health emergency of international concern. The decision comes after international spread was documented, with ebola symptoms cases already reported across the border in Kampala.
Two confirmed cases were reported in Kampala, Uganda, on 15 and 16 May after travel from the Democratic Republic of the Congo. Both people were admitted to intensive care units, and a laboratory confirmed case was reported in Kinshasa on 16 May, with the WHO updating its statement on 17 May 2026.
WHO emergency declaration
WHO Director-General said, "The event constitutes a public health risk to other States Parties through the international spread of disease." The organization said the event requires international coordination and cooperation to understand the extent of the outbreak and to coordinate surveillance, prevention and response efforts.
The decision also draws a line under the scale of the outbreak. The WHO said the event does not meet the criteria of pandemic emergency as defined in the International Health Regulations, even as it moves ahead with its highest alert mechanism for cross-border spread.
Kampala and Kinshasa cases
Kampala is the clearest sign that the outbreak has already crossed into another country. The two cases there were reported after travel from the Democratic Republic of the Congo, and both were serious enough to require intensive care.
Kinshasa adds a second point of concern inside the Democratic Republic of the Congo itself. A laboratory confirmed case was reported there on 16 May, and the WHO later updated its public statement to reflect that case on 17 May 2026.
Border countries on alert
Neighboring countries sharing land borders with the Democratic Republic of the Congo are considered at high risk for further spread. The WHO tied that risk to population mobility, trade and travel linkages, and ongoing epidemiological uncertainty.
The next step is a WHO Emergency Committee, which the organization said it will convene as soon as possible to advise on proposed temporary recommendations for States Parties. For public health authorities in the Democratic Republic of the Congo, Uganda and border countries, that means the most immediate question is how quickly surveillance and response measures can be aligned across the region.
