The Bundibugyo virus outbreak in the Democratic Republic of the Congo and Uganda has escalated into a Public Health Emergency of International Concern (PHEIC), declared by WHO on May 17. As of late May, DRC reported 906 suspected cases and 223 deaths, with Uganda confirming 9 cases and 1 death. The outbreak, centered in Ituri province and spreading to North and South Kivu, is caused by a rare Ebola strain with no licensed vaccines or specific treatments.

WHO Director-General Tedros visited Bunia, urging community cooperation amid attacks on health workers and protests over burial protocols. MSF warned the spread is outpacing the response, with hundreds of samples untested. In response, WHO convened expert groups that prioritized three experimental therapies for clinical trials: monoclonal antibodies MBP134 and maftivimab, and antiviral remdesivir, with obeldesivir proposed for post-exposure prophylaxis.

Two vaccine candidates—rVSV Bundibugyo (IAVI, 7–9 months away) and ChAdOx1 Bundibugyo (Oxford/Serum Institute, 2–3 months pending animal data)—are in development. Gavi committed $50 million to accelerate vaccine access. International travel restrictions were imposed by the US, Canada, and others, while a Kenyan court suspended a planned US Ebola quarantine facility amid sovereignty concerns.

The US CDC also enhanced screening for travelers from affected countries. The outbreak highlights critical gaps in medical countermeasures for non-Zaire Ebola species, with global health agencies racing to contain the virus through surveillance, contact tracing, and experimental interventions.
