- WHO declared the Ebola outbreak in the Democratic Republic of the Congo and Uganda a public health emergency of international concern on 17 May 2026.
- U.S. funding cuts to the WHO beginning in early 2025 forced the agency to slash its 2026/27 budget and lay off staff, which WHO epidemiologists say has hampered outbreak response.
- CDC reported 336 suspected cases of the Bundibugyo Ebola strain with 88 deaths, a mortality rate of 20‑50 % among known cases as of 17 May.
- Oxford and Moderna are accelerating a multivalent filovirus vaccine programme that targets Bundibugyo, Zaire ebolavirus and Marburg, a effort urged by epidemiologist Adrian Esterman to fast‑track trials.
Why it matters: The WHO’s emergency declaration forces a rapid response, but U.S. funding cuts have weakened its capacity, risking higher deaths; accelerated vaccine development could save lives and curb the outbreak.
