Bundibugyo Virus Outbreak: Chronology of Ebola Case Findings in Congo and Uganda
The World Health Organisation (WHO) has officially declared the Ebola virus outbreak affecting the Democratic Republic of Congo (DRC) and Uganda as a Public Health Emergency of International Concern (PHEIC) on 17 May 2026. This decision follows reports of a sharp increase in cases since early May, with the death toll now approaching 100 individuals.
This particular outbreak has been identified as being caused by the Bundibugyo species of the Ebola virus. Based on collected data, an increase in cases began to be significantly detected in the border regions between Congo and Uganda in early May 2026. The rapid pattern of spread within local communities has triggered concerns regarding wider cross-border transmission.
By mid-May, field reports indicated that the infection had spread to several health zones, presenting with severe clinical manifestations in patients. To date, nearly 100 deaths have been recorded due to complications from the Bundibugyo virus, prompting a rapid response from regional and international health authorities.
In its official statement, the WHO emphasised that the situation in the DRC and Uganda meets the criteria for a global emergency. The designation of PHEIC status aims to mobilise international coordination, emergency funding, and the strengthening of surveillance at border crossings.
“The Ebola epidemic caused by the Bundibugyo virus in the Democratic Republic of Congo and Uganda is declared a public health emergency of international concern,” the WHO official statement read (17/05/2026).
Rapid response teams have been deployed to hotspots to conduct contact tracing and patient isolation. The primary challenges in the field currently include access to remote areas and the availability of medical logistics to manage large numbers of patients simultaneously.
The public is urged to increase vigilance regarding symptoms such as high fever, muscle pain, and unusual bleeding, and to report immediately to the nearest health facility. The WHO continues to coordinate with the ministries of health in both countries to suppress the rising fatality rate.
