Overview
- The World Health Organization elevated the outbreak to a Public Health Emergency of International Concern after reporting roughly 50 confirmed cases, nearly 600 suspected infections and about 139 suspected deaths in the Democratic Republic of Congo and cases exported to Uganda.
- Detection was delayed because initial tests targeted the more common Zaire strain and many early deaths occurred outside health facilities, allowing the virus to spread for weeks before sequencing identified Bundibugyo.
- Governments and agencies have enacted travel measures and screenings, including a 30-day CDC airport screening order in the United States and a DHS rule directing affected flights to land at Washington‑Dulles, which produced operational incidents such as an Air France flight diverted to Montreal.
- Response operations face major obstacles from violence, militia control, large internal displacement and poor access in eastern DRC, which are hindering contact tracing, safe burials and delivery of supplies and laboratory samples.
- Health experts warn the outbreak could worsen without rapid surge capacity because Bundibugyo requires different diagnostics and there are no approved countermeasures, and some observers say recent cuts to donor and U.S. public‑health staffing have reduced surge response ability.
