On May 16, 2026, the World Health Organization (WHO) declared a Public Health Emergency of International Concern (PHEIC), its highest level of alarm, as the Bundibugyo virus (BVD) rapidly spread across northeastern Democratic Republic of the Congo (DRC) and crossed the border into Uganda. With no approved vaccine and no targeted therapeutics, this rapidly spreading, often fatal hemorrhagic fever poses an urgent, underappreciated threat to workers around the globe, particularly those in healthcare settings.
