WHO Declares Public Health Emergency Over Ebola Bundibugyo Outbreak in Congo and Uganda
On Sunday, May 17, 2026, the World Health Organization (WHO) declared the current Ebola outbreak in the Democratic Republic of Congo (DRC) and Uganda a public health emergency of international concern. The declaration comes as health authorities struggle to contain the spread of the rare Bundibugyo virus strain, which has already resulted in significant morbidity and mortality across the region.
WHO Director-General Tedros Adhanom Ghebreyesus made the announcement following reports of more than 300 suspected cases and 88 deaths. While the situation is critical, the WHO has clarified that the outbreak does not meet the specific criteria required to be classified as a pandemic emergency, such as the COVID-19 pandemic. Health officials have advised against the closure of international borders at this time.
Understanding the Bundibugyo Virus
The current crisis is driven by the Bundibugyo virus, a rare variant of the Ebola disease. This specific strain presents a unique challenge to medical professionals because there are currently no approved therapeutics or vaccines specifically for the Bundibugyo variant.
This is only the third time the Bundibugyo virus has been reported globally. Its history includes a notable outbreak in Uganda’s Bundibugyo district during 2007–2008, which infected 149 people and resulted in 37 deaths. The rarity of this strain means that clinical experience and specialized treatment protocols are limited compared to more common Ebola variants.
Current Outbreak Status and Geographical Spread
The outbreak was first reported on Friday in the eastern province of Ituri, Congo, a region situated near the borders of Uganda and South Sudan. As of Saturday, the Africa Centres for Disease Control and Prevention (Africa CDC) reported 336 suspected cases and 87 deaths.
The geographical distribution of the disease is heavily concentrated in the DRC, which accounts for nearly all reported cases. However, the virus has successfully crossed into neighboring Uganda. Key details regarding the spread in Uganda include:
- Imported Cases: Uganda confirmed one case that was imported from Congo; the patient subsequently died at a hospital in Kampala.
- Secondary Reports: A second case has been reported in Kampala. The WHO noted that these two cases had no apparent links to each other, though both patients had traveled from Congo.
Key Takeaways for Public Health
- Emergency Status: The outbreak is officially a public health emergency of international concern.
- Virus Variant: The outbreak involves the Bundibugyo strain, for which no vaccine or specific treatment exists.
- Primary Locations: The virus is centered in Congo’s Ituri province and has spread to Kampala, Uganda.
- Pandemic Risk: The WHO does not currently classify this as a pandemic and advises against border closures.
Frequently Asked Questions

Currently, there are no approved vaccines or specific therapeutics for the Bundibugyo variant of the Ebola virus.
How is the virus spreading?
Evidence suggests the virus is spreading through regional movement, with cases in Uganda being linked to travel from the Democratic Republic of Congo.
Looking Ahead
As health organizations mobilize to respond to this emergency, the focus remains on containment, surveillance, and supporting local healthcare infrastructures in Ituri and Kampala. The international community’s ability to monitor the spread and manage the lack of specific therapeutics will be vital in preventing further loss of life.
