How the 2026 Bundibugyo Ebola outbreak spread through the health zones of eastern and northern DR Congo: from three zones in Ituri in mid-May to 65 zones in seven provinces by mid-October, with exported cases in Uganda and Kenya. Each health zone (zone de santé, the unit DRC's health system reports by) is coloured by the month of its first confirmed case: red May, orange June, yellow July, green August, teal September, cyan October. Grey: the zones of an affected province that have no confirmed case (yet). Circles mark Uganda's 20 confirmed cases in Kampala (May–June; declared over on 28 July) and Kenya's single imported case in Nairobi (October); the line traces that traveller's route from Buta via Kisangani, Beni and Kampala. The bar counts confirmed deaths in DRC. Simplifications: confirmed cases only, no probable or suspected cases. A zone is coloured from the first date a source lists it as affected, and appears at the next keyframe; keyframes follow the weekly WHO situation reports, so dates are rounded to the sitrep week. Zone boundaries are OpenStreetMap's (2021). The newest zone, Dakwa (first case 8 October), is not in that boundary data and is drawn as Ango zone, which WHO shades on its map. Cases evacuated to Germany, France and the Netherlands appear only in the event notes.
