DR Congo Ebola Outbreak Surpasses 10,000 Cases as Virus Spreads Across Borders
The fast-moving Bundibugyo epidemic has become the second-deadliest Ebola outbreak in history, spreading to four other nations while lacking approved vaccines or targeted antiviral treatments.
The Democratic Republic of the Congo has surpassed 10,000 confirmed Ebola cases in an outbreak spreading across central and eastern Africa, health authorities reported. Congolese officials officially declared the epidemic on May 15, 2026, following retrospectively identified cases from March.
The National Public Health Institute recorded 10,060 confirmed cases and 4,887 deaths as of Oct. 25, representing a 48.6 percent fatality rate. The virus has reached 66 health zones across eight provinces, with Ituri province accounting for 71.7 percent of all confirmed cases.
The current epidemic took fewer than 40 days from response activation to reach 1,000 confirmed cases, according to the U.S. CDC. By contrast, the 2018 to 2020 Congolese outbreak took roughly 235 days to reach that milestone. The epidemic is now the second-largest and second-deadliest in global history, behind only the 2014 to 2016 West Africa outbreak.
The Bundibugyo species of the virus is driving the outbreak. Unlike the Zaire strain, the Bundibugyo species has no approved vaccines or targeted antiviral therapeutics. The World Health Organization declared the outbreak a Public Health Emergency of International Concern in mid-May.
Confirmed cases have spread to Uganda, Kenya, Nigeria, and France. Kenya reported nine cases and one death, though the U.S. CDC reported two deaths, all linked to travel through Uganda. Nigeria confirmed one case in Abuja on Oct. 20, 2026, and traced 44 contacts.
The patient in Nigeria, the wife of a Swiss diplomat, contracted the virus in Uganda and was medically evacuated to Switzerland. Dr. Patrick Otim from the WHO stated that investigators are tracking her travel from Uganda to identify the source of exposure.
Uganda recorded 20 cases and two deaths, though the U.S. CDC reported 21 cases and three deaths. Health authorities declared Uganda Ebola-free in August. Uganda's health minister announced that citizens returning with a travel history to the DRC must complete a mandatory 21-day quarantine.
Response teams in eastern Congo face disruptions from active armed conflict, bad road infrastructure, and community distrust. Residents in Tshopo province killed a nurse after accusing the worker of spreading the virus through local water. WHO Director-General Tedros Adhanom Ghebreyesus condemned the killing and stated that healthcare workers must always be protected.
Africa CDC Director-General Dr. Jean Kaseya stated that the response must move faster with stronger coordination and decisive political leadership. The World Health Organization continues to advise against any blanket travel or trade restrictions on affected countries.
Researchers administered the first vaccine dose in the Phase 2/3 Tumaini clinical trial in Bunia to evaluate experimental Bundibugyo vaccines. The trial will expand enrollment in Bunia while health teams in Nigeria and Kenya continue tracking contacts. African health ministers are scheduled to convene an emergency virtual summit to coordinate cross-border containment measures.
