Ebola Outbreak Linked to Bundibugyo Virus Spreads Across DRC and Uganda, Declared International Health Emergency
A rapidly evolving Ebola outbreak, caused by the Bundibugyo virus, is currently impacting the Democratic Republic of the Congo (DRC) and Uganda. As of June 13, 2026, the outbreak has led to a significant number of confirmed cases and deaths in both nations, prompting the World Health Organization (WHO) to declare it a Public Health Emergency of International Concern (PHEIC). [4, 5, 7, 12, 13, 15, 18]
In the Democratic Republic of the Congo, a cumulative total of 676 confirmed cases, including 136 deaths, had been reported by June 10, 2026. The majority of these cases are concentrated in the Ituri Province, which accounts for approximately 93% of the confirmed cases in the DRC. [4, 8] The outbreak has also seen geographic expansion, with cases reported across 29 health zones in Ituri, North Kivu, and South Kivu provinces. [4]
Uganda has reported 19 confirmed cases, including two deaths, as of June 11, 2026. The outbreak in Uganda is epidemiologically linked to transmission originating in the DRC, with evidence of both imported infections and secondary transmission among contacts and healthcare workers. The cases in Uganda have been reported in the districts of Kampala and Wakiso. Notably, Uganda has not reported any new cases in the six days preceding June 11, and there has been no documented community transmission within the country to date. [4, 14]
This outbreak is caused by the Bundibugyo ebolavirus (BDBV), a less common strain of Ebola that has historically been associated with high fatality rates, ranging from 30% to 50% in previous outbreaks. [6, 11, 15, 17] Unlike outbreaks caused by the Zaire ebolavirus, there are currently no licensed vaccines or specific treatments for the Bundibugyo virus. [7, 11, 12] This lack of specific medical countermeasures complicates response efforts, as existing Ebola treatments were developed for different strains. [7]
The situation is exacerbated by challenging local conditions in the affected regions, including limited healthcare infrastructure, ongoing armed conflict, population displacement, and frequent cross-border movement. [7, 9, 11, 18] These factors hinder detection, treatment, prevention, and the ability to contain the spread of the virus effectively.
National authorities in the DRC and Uganda, in collaboration with the WHO and international partners, are implementing a comprehensive package of response measures. These include strengthening surveillance, increasing laboratory capacity, enhancing infection prevention and control, setting up treatment centers, and engaging in risk communication and community outreach. [4, 14] A regional preparedness and prioritization framework is also guiding readiness activities across the African Region. [4]
