WHO Declares Emergency Over Bundibugyo Outbreak in DRC and Uganda

A Global Health Emergency Declared

The World Health Organization (WHO) declared a public health emergency of international concern over an Ebola outbreak linked to the Bundibugyo virus in the Democratic Republic of Congo (DRC) and Uganda. Announced on May 18, 2026, this declaration came after over 300 suspected cases and 88 deaths, with lab-confirmed cases in Kinshasa and Kampala. The WHO said the outbreak doesn’t meet pandemic criteria like COVID-19 but warned of regional risks. The CDC declared the outbreak on September 4, 2025, with 64 confirmed or probable cases and 45 deaths as of November 5, 2025. However, underreporting may have made the crisis seem bigger. This highlights how public health emergencies often intersect with political instability, as the outbreak spreads in areas affected by conflict and displacement.

A Rare and Deadly Virus

“We’ve learned that delays in detection and response can let the virus spread quickly.”

The current outbreak is linked to the Bundibugyo virus, a rare Ebola variant with no approved treatments or vaccines. First discovered in 2007-2008 in Uganda’s Bundibugyo district, this strain has only been found twice before in DRC and Uganda. The earliest known suspected case was a 59-year-old man who got sick on April 24 and died on April 27, according to the CDC. WHO Director-General Tedros Adhanom Ghebreyesus said the outbreak started in April and the first case remains unknown, showing how hard it is to trace the virus’s origin. Without specific treatments, containment is harder, as the WHO’s regional office sent 35 experts and 7 tons of medical supplies to Ituri province, where the outbreak began.

Challenges in Containment

The outbreak’s spread is made worse by ongoing conflict in eastern DRC, where the M23 rebel group, backed by Rwanda, has displaced hundreds of thousands. Movement caused by mining and conflict has made contact tracing difficult, according to the Africa Centres for Disease Control and Prevention (Africa CDC). Limited testing and resistance to health measures may have led to underreporting, as a 2024 Africa CDC report found that 70% of Ebola outbreaks in the region happen in areas with weak governance and ongoing violence. Despite these challenges, the WHO’s regional office has expanded surveillance and sent response teams to address the crisis.

Historical Precedent and Past Failures

The WHO’s response to this outbreak has been compared to past failures, including the 2014-2016 West Africa Ebola outbreak, which killed over 11,000 people. While the WHO didn’t declare a public health emergency for that outbreak, it faced criticism for slow action. In 2025, the WHO’s handling of mpox outbreaks in Congo also drew scrutiny for delayed resource mobilization, though no formal declaration was made. Dr. Tedros admitted, ‘We’ve learned that delays in detection and response can let the virus spread quickly.’ The WHO’s repeated struggles to act fast in past outbreaks have raised questions about its ability to respond in conflict zones, where political instability weakens public health systems.

Global Response and U.S. Involvement

The U.S. CDC has sent 30 personnel to the DRC and plans to add more. However, CDC officials haven’t confirmed if any Americans were exposed. A 2026 travel advisory warns U.S. citizens to avoid contact with sick people in affected areas. The WHO’s declaration aims to boost international aid, but experts say success depends on tackling both medical and political challenges in conflict zones. The CDC’s cautious stance on U.S. risk highlights tensions between public health transparency and geopolitical sensitivity, as the U.S. government hasn’t confirmed any cases among its citizens.

“This outbreak started in April, and we still don’t know the index case. Without understanding the full scope, containment efforts will remain reactive.”

Implications for Global Health Governance

The WHO’s declaration highlights how public health crises often overlap with political instability. The Bundibugyo outbreak’s spread into Uganda and the DRC’s conflict zones show how health emergencies are tied to socio-political dynamics. The Africa CDC emphasized that 70% of Ebola outbreaks in the region occur in areas with weak governance and ongoing violence, suggesting that fixing these root causes is as important as developing vaccines and treatments. The WHO’s repeated delays in past outbreaks have damaged trust in its leadership, prompting calls for reforms in global health institutions. As the Bundibugyo virus spreads, the world must face the reality that public health crises are symptoms of deeper systemic failures.

Addressing the Crisis: Next Steps

The WHO’s declaration aims to mobilize international aid, but experts say success depends on addressing both medical and political challenges. A 2025 Science study found that community engagement and conflict resolution are as critical as medical interventions in controlling outbreaks. As Dr. Kaseya noted, This outbreak started in April, and we still don’t know the index case. Without understanding the full scope, containment efforts will remain reactive. The global health community now faces the urgent task of balancing rapid response with long-term strategies to prevent future crises in conflict-affected regions. This outbreak also raises critical questions about the WHO’s ability to adapt its protocols in the face of evolving threats, especially in areas where political instability undermines public health infrastructure.
