WHO Declares DRC Ebola a Global Emergency: Bundibugyo Strain Has No Vaccine

# WHO Declares DRC Ebola a Global Emergency: Bundibugyo Strain Has No Vaccine

> **Quick answer:** On May 17, 2026, the WHO declared the Ebola outbreak in the Democratic Republic of the Congo and Uganda a Public Health Emergency of International Concern (PHEIC). The outbreak involves the Bundibugyo strain — for which no licensed vaccine or antiviral exists — with 80 suspected deaths and confirmed cases reaching Kampala and Kinshasa. International travel screening and emergency response have been activated.

The DRC Ebola outbreak 2026 is unlike anything the global health system has faced in nearly a decade. Unlike previous major outbreaks that involved the Zaire strain — for which an effective vaccine (rVSV-ZEBOV) exists — this one is driven by the Bundibugyo virus, a strain so rare it has only triggered two documented outbreaks in recorded history, and for which doctors have no approved shot to deploy.
