The World Health Organization confirmed a new Ebola Bundibugyo outbreak in the Democratic Republic of the Congo’s Ituri Province on May 15, 2026. Laboratory analysis in Kinshasa identified the virus in samples from the Mongbwalu and Rwampara health zones, where officials report up to 80 suspected community deaths.
The National Institute of Biomedical Research (INRB), the reference laboratory in Kinshasa, confirmed the presence of the Ebola Bundibugyo species in 8 of 13 samples collected from suspected cases. These cases are linked to a cluster of severe illness and deaths reported in the Mongbwalu and Rwampara health zones of the north-eastern Ituri Province.
Confirmation of the Bundibugyo Strain in Ituri
The identification of the Bundibugyo species marks a specific challenge for health authorities. This strain was first identified in 2007 in the Bundibugyo district of western Uganda, an event that resulted in 131 reported cases and 42 deaths, representing a case fatality rate of 32%.
In the current Ituri outbreak, patients have presented with symptoms including fever, generalized body pain, weakness, and vomiting. Some cases have also exhibited bleeding. According to the World Health Organization, several patients deteriorated rapidly and died, leading to significant concern regarding the scale of transmission within the affected communities.
Mortality Rates and Community Spread
Data regarding the current death toll varies across reporting agencies. The World Health Organization and Reuters report a total of 80 community deaths suspected to be caused by Ebola Bundibugyo. Direct Relief reports that the outbreak has caused at least 67 deaths.
The rapid deterioration of patients has alarmed health experts. Reporting from The New York Times indicates that dozens of deaths and hundreds of infections are suspected, with experts expressing concern that the outbreak had not been detected sooner.
Regional Containment and WHO Response
The World Health Organization is scaling up support to the government of the Democratic Republic of the Congo to manage the crisis. An emergency preparedness and response team, along with the WHO representative, has already deployed to Ituri. This mission was instrumental in the investigations that led to the confirmation of the outbreak in the two identified health zones.
Current efforts are focused on strengthening outbreak control measures to prevent the virus from spreading beyond Mongbwalu and Rwampara. The WHO team is working directly with provincial and national health authorities to coordinate the response.
While the WHO is scaling up its operational support, some reports indicate the outbreak has been declared a Public Health Emergency of International Concern, reflecting the severity of the virus and the risk of cross-border transmission.
Patterns of Recurrence in the DRC
This outbreak follows closely on the heels of previous Ebola activity in the region. The most recent outbreak, located in Kasai province, was declared over on December 1, 2025. That specific event lasted three months and resulted in 45 deaths out of 64 total cases.
The recurrence of the virus in different provinces—moving from Kasai in late 2025 to Ituri in May 2026—highlights the persistent volatility of Ebola in the Democratic Republic of the Congo. The shift to the Bundibugyo strain in the north-east adds a layer of complexity to the medical response, as the region must now manage a species of the virus with its own distinct clinical history.
The current situation remains fluid. Authorities are continuing to analyze samples and track suspected cases to determine the exact boundary of the transmission zone in Ituri Province.
