DR Congo’s Bundibugyo Ebola Outbreak Becomes Country’s Largest

What changed

The World Health Organization says an Ebola outbreak in the Democratic Republic of the Congo, caused by the Bundibugyo virus, is now the largest in the country’s history. Since it was declared on 15 May 2026, cases have been reported in the DRC, France, Kenya, Nigeria and Uganda.

Why it matters

This is no longer a single-country outbreak on the facts available. Five countries are now part of the recorded picture, giving health authorities across Africa and beyond a shared problem to track.

The geography matters, but the scale remains hard to judge from the information released so far: no case, death, recovery or vaccination totals are provided. That leaves the central question open: not whether the outbreak is historically large for the DRC, but how widely and severely it is affecting people now.
