At least 49 people have died and 452 more have been infected in an Ebola outbreak that spread from northeastern Congo into Uganda before the virus was correctly identified.
Weeks of negative results delayed the response because frontline clinics were testing for the Zaire strain, while the outbreak was caused by the Bundibugyo species.
Samples from many patients reached Congo's national biomedical institute in Kinshasa only after some had already died, where broader screening finally detected the culprit.
The failure has exposed Congo's chronic shortage of high-quality diagnostic tests, especially in remote areas where dangerous pathogens often emerge first.

Bundibugyo Ebola Epidemic 2026: Escalating Cases, Detection Gaps, and Humanitarian Catastrophe in Central Africa
Overview
As of June 2, 2026, the Bundibugyo Ebola epidemic has rapidly escalated in the Democratic Republic of the Congo (DRC) and spread into Uganda, with over 1,000 cases and more than 200 deaths reported. The World Health Organization declared the outbreak a Public Health Emergency of International Concern on May 16, after which cases more than doubled. The hardest-hit areas are Ituri, North Kivu, and South Kivu provinces, with new cases now appearing in major cities like Bunia and Goma. This widening spread highlights the urgent need for stronger public health measures and international support to contain the crisis.
