WHO Says Congo Ebola Outbreak Began In February And Is Fastest Growing
WHO said on August 10, 2026 that genetic sequencing shows the current Ebola outbreak in the Democratic Republic of Congo began in February 2026, not in mid-May when it was declared.[1]
The government of the DRC reports roughly 4,200 confirmed Ebola cases and more than 1,900 deaths in the outbreak.[1] WHO calls it the fastest-growing Ebola outbreak on record and says the surge has been driven by late detection, fighting in conflict-affected areas, and a Bundibugyo virus strain without approved vaccines or treatments.[1]
Sequencing shows the outbreak began in February 2026, implying infected people carried the virus for months before authorities recognized a cluster in mid-May.[1] That late detection, combined with fighting in hard-to-reach areas and the Bundibugyo strain's lack of approved vaccines or treatments, has complicated response efforts.[1]
