WHO Reports Bundibugyo Ebola Increase in Congo as Uganda Tracks Cross-Border Cases

ByDental Info

The World Health Organization said confirmed Bundibugyo Ebola cases and deaths had increased substantially in the Democratic Republic of the Congo, while Uganda reported two confirmed cases in Kampala in May.

The World Health Organization said July 17 that confirmed cases and deaths from Bundibugyo Ebola virus disease had increased substantially in the Democratic Republic of the Congo since its previous update, keeping an outbreak in the country’s northeast at the center of an international public-health response.

The outbreak began in Ituri Province and has also raised cross-border concerns after two laboratory-confirmed cases were reported in Kampala, Uganda, in May. One of those patients died. The people were traveling from the Democratic Republic of the Congo, according to WHO.

WHO has urged authorities in both countries to maintain surveillance, confirm suspected infections in laboratories, strengthen infection prevention and control, expand treatment capacity and monitor people who may have been exposed.

Outbreak began in Ituri Province

The Democratic Republic of the Congo confirmed the outbreak in May 2026 in the Rwampara and Mongbwalu health zones of Ituri Province. The country’s health ministry officially declared it the Democratic Republic of the Congo’s 17th Ebola outbreak.

The virus involved is Bundibugyo virus, a distinct Ebola species. The outbreak’s location and movement of people between Congo and Uganda have complicated the response, making early detection and coordination across borders important even as health officials work to determine where transmission is occurring.

WHO said the latest confirmed case cited in its July update was identified on June 21. That patient recovered and was discharged. The agency said, however, that confirmed cases and deaths in the Democratic Republic of the Congo had risen substantially since the preceding update.

The July update did not present a complete current total in the information publicly summarized by WHO, so the scale of the increase cannot be expressed here as a single case or death figure. The reported rise, along with the continuing need for contact monitoring and laboratory confirmation, indicates that response teams are still working to identify infections and interrupt transmission.

Uganda reported cases in Kampala

Uganda’s cases prompted WHO to issue recommendations covering isolation, diagnosis, contact tracing, monitoring and safe burials. The Kampala infections demonstrated the practical cross-border risk associated with travel from the outbreak area, while not establishing sustained community transmission across every affected location.

WHO declared the epidemic a public health emergency of international concern on May 17, 2026. That designation is used for events that pose a risk of international spread and may require a coordinated international response. The decision brought heightened attention to measures intended to limit further transmission between countries.

WHO has described the response as involving rapid-response teams, medical supplies, surveillance and laboratory work. Officials are also assessing infection-prevention and control practices, establishing safe treatment centers and engaging communities in affected areas.

Response challenges remain

Occupational exposure risks and inadequate infection-prevention controls are among the operational concerns identified in WHO’s outbreak update. Health workers and other responders depend on protective procedures, timely testing and safe treatment arrangements to reduce the risk of additional infections.

Reuters reported from Bunia that a WHO official said the outbreak was still spreading largely undetected, highlighting the challenge of finding cases that may not reach health facilities or be identified quickly. That concern makes surveillance and contact monitoring central to the next phase of the response.

The immediate next steps are continued case finding, laboratory confirmation, monitoring of contacts, infection-control assessments and treatment support in the Democratic Republic of the Congo and Uganda. WHO’s July 17 update did not announce an end date for those measures or declare the outbreak contained.
