DRC Ebola Outbreak: Cases Surpass 10,000 in Fastest-Growing Outbreak
Confirmed Ebola cases in the Democratic Republic of the Congo have surpassed 10,000 in the fastest-growing outbreak in the country’s history, with government data released on Tuesday putting infections at 10,060 and deaths at 4,887.
- The current outbreak in the Democratic Republic of the Congo is driven by the Bundibugyo virus, a rare Ebola strain for which no vaccine or approved specific treatment previously existed.
- Data from the DRC Ministry of Public Health indicates a crude case fatality rate approaching 50 percent, with 4,887 deaths recorded among the 10,060 confirmed cases.
- The World Health Organization reported that the outbreak has expanded internationally with imported cases detected in Uganda, Kenya, Nigeria, and a case evacuated to Switzerland.
Geographic Spread Across the Democratic Republic of the Congo and Neighbouring Nations
The epidemic began after the virus was first detected on May 15, 2026, in the northeastern Congolese province of Ituri. The outbreak has since expanded across 66 health zones in eight provinces, most recently reaching the Wapinda Health Zone in Nord-Ubangi Province. Ituri and eastern North Kivu province account for the majority of reported cases, complicated by regional security challenges and armed groups.

Outside the Democratic Republic of the Congo, regional transmission has prompted strict border measures. In Uganda, Health Minister Chris Baryomunsi announced that citizens returning from the DRC must quarantine for 21 days at their own expense after the country recorded 20 cases and two deaths over the summer. Kenya has reported nine confirmed cases and two fatalities, while Nigeria instituted heightened airport screening after confirming an imported case in the Federal Capital Territory of Abuja. Swiss authorities confirmed that a woman married to a Swiss diplomat contracted the virus during a September visit to Uganda, developed symptoms after travelling to Nigeria, and was subsequently evacuated to Switzerland for treatment.
Tumaini Vaccine Trials Begin to Address Unmonitored Transmission
According to the Africa Centres for Disease Control and Prevention, at least 95 percent of new cases must originate from monitored contact chains to achieve control, whereas approximately 80 percent of current cases stem from unmonitored transmission chains. At least half of those who have died were never admitted for clinical treatment.
To address the absence of approved countermeasures against the Bundibugyo strain, clinical trials evaluating existing vaccines have begun. The World Health Organization announced the rollout of the first clinical trial administering the Tumaini vaccine in Ituri, while testing also assesses whether the Ervebo vaccine, effective against the Zaire strain, provides cross-protection against the Bundibugyo variant.
