Overview
- WHO declared a public health emergency of international concern on May 17 after the Bundibugyo Ebola outbreak expanded across northeastern DRC and spilled into Uganda, prompting the agency to convene its emergency committee.
- As of May 20 health officials report roughly 600 suspected cases and about 139 suspected deaths, with more than 50 laboratory confirmations and infections detected in cities including Bunia, Goma and Kampala.
- The outbreak is driven by Bundibugyo ebolavirus, a rarely seen species for which there are no approved vaccines or strain‑specific therapeutics, leaving response teams dependent on supportive care and experimental options.
- Response is scaling up with WHO, Africa CDC and the U.S. CDC deploying experts and supplies, U.S. authorities restricting entry for recent travelers from affected areas and evacuating infected or exposed Americans to Europe for treatment.
- Containment is hampered by delayed detection—early tests targeted the Zaire strain—limited local diagnostic capacity, active conflict and high population movement in the mining region, which raises the risk of further regional spread.
