The World Health Organization on Saturday declared the ongoing Ebola outbreak in the Democratic Republic of Congo and Uganda a public health emergency of international concern, the highest level of alarm the global health body can issue. The declaration comes as the outbreak, caused by the rare Bundibugyo virus disease, has grown to more than 300 suspected cases with at least 88 confirmed deaths across both nations.
WHO Director-General Tedros Adhanom Ghebreyesus announced the decision following an emergency committee meeting, noting that while the outbreak does not yet meet the criteria for a pandemic, neighboring countries face a high risk of cross-border transmission. The outbreak was first reported in the eastern Congolese province of Ituri, a region that borders both Uganda and South Sudan, making containment particularly challenging given the porous borders and ongoing regional instability.
The Bundibugyo virus represents one of the most concerning aspects of this outbreak. It is only the third time in history that this rare strain of Ebola has been detected in humans. Unlike the more common Zaire strain of Ebola, for which vaccines and therapeutics have been developed and deployed successfully in recent years, there are currently no approved vaccines or treatments specifically targeting the Bundibugyo virus. This leaves health workers relying solely on supportive care and traditional infection prevention measures.
The Democratic Republic of Congo accounts for all but two of the more than 300 suspected cases, with Uganda confirming two cases linked to cross-border movement from Ituri province. More than 20 Ebola outbreaks have occurred in Congo and Uganda over the past several decades, but the absence of specific medical countermeasures for Bundibugyo virus disease makes this particular outbreak especially dangerous. International health organizations are now scrambling to accelerate research into potential treatments.
The PHEIC declaration is expected to mobilize significant international resources and funding for outbreak response. Health authorities in the region are scaling up surveillance, contact tracing, and community engagement efforts while researchers urgently work to adapt existing Ebola countermeasures for use against the Bundibugyo strain. The WHO has urged all countries in the region to heighten their preparedness measures and strengthen border health screening protocols to prevent further international spread of the virus.
