As of June 6, 2026, the World Health Organization (WHO) and international health authorities are responding to an outbreak of Ebola disease caused by the Bundibugyo virus in the Democratic Republic of the Congo (DRC) and Uganda. The WHO declared the outbreak a Public Health Emergency of International Concern on May 17, 2026, following confirmed cases in both nations.
Current Status of the Ebola Outbreak
The outbreak, which involves the Bundibugyo virus, was officially declared on May 15, 2026, by health ministries in the DRC and Uganda, according to the World Health Organization. As of May 21, 2026, there were 746 suspected cases and 176 deaths among suspected cases reported in the DRC. Across both countries, officials have confirmed 85 cases and ten deaths. While the DRC reports transmission concentrated in the Ituri, North Kivu, and South Kivu provinces, Uganda has reported two imported cases with no evidence of local transmission.
International Response and Travel Measures
In response to the risk of international spread, the U.S. Centers for Disease Control and Prevention (CDC) and the Department of Homeland Security implemented enhanced screening measures on May 18, 2026, as reported by the CDC. Air passengers arriving from the DRC, South Sudan, and Uganda are being re-routed to four designated U.S. airports: Washington-Dulles (IAD), Atlanta Hartsfield-Jackson (ATL), George Bush Intercontinental (IAH), and John F. Kennedy (JFK). While South Sudan has reported no cases, it is included in these measures due to its shared borders with the affected region.
Medical Care for Exposed Individuals
On May 17, 2026, an American national working in the DRC tested positive for the Bundibugyo virus. The patient was transported to Germany for specialized care, where they remain in stable condition, according to the CDC. Germany was selected for treatment due to its existing infrastructure and experience in managing Ebola patients. High-risk contacts associated with this individual have been moved to Germany and the Czech Republic for monitoring and remain asymptomatic.
Understanding Ebola Virus Disease
Ebola, or Ebola virus disease (EVD), is a zoonotic viral hemorrhagic fever. Symptoms typically appear between two days and three weeks after exposure, according to Wikipedia. Early indicators include fever, sore throat, muscle pain, and headaches, which may progress to vomiting, diarrhea, and internal or external bleeding. The disease spreads through direct contact with the blood or body fluids of an infected person or contaminated objects. While mortality rates historically range from 25% to 90%, the specific viral strain and the timing of medical intervention significantly influence patient outcomes.
Key Facts About the 2026 Outbreak
