Event description
Since our last update of 07 June 2026 (Situation Report #4), the Bundibugyo virus disease (BVD) outbreak situation in the Democratic Republic of the Congo has continued to evolve, with sustained transmission and increasing geographic spread being reported. In Uganda, the outbreak situation remains stable, with no new confirmed cases reported during the past week.
Democratic Republic of the Congo
In the Democratic Republic of the Congo, intense community transmission and geographic expansion continue to characterize the outbreak. Since 07 June 2026, a total of 258 new confirmed cases, including 91 new confirmed deaths, have been reported, representing a 60.0% increase in confirmed cases and a 90.1% increase in confirmed deaths reported. As of 14 June 2026, a cumulative total of 808 laboratory-confirmed cases, including 192 confirmed deaths [case fatality ratio (CFR) 23.8%], have been reported across the three affected provinces of Ituri, North Kivu, and South Kivu.
The number of affected health zones has increased from 25 to 31, including 20 of 36 health zones in Ituri Province, 10 of 34 in North Kivu Province, and one of 34 in South Kivu Province. Newly reporting health zones include Tchomia, Kambala and Nia-Nia in Ituri Province and Mabalako, Masereka, and Vuhovi in North Kivu Province. However, the identification of cases in some of these newly reporting health zones may reflect previously undetected transmission rather than recent introduction of the virus. Epidemiological investigations indicate that transmission had likely been occurring in some of these areas for several weeks before the first cases were confirmed and reported. In contrast, health zones such as Nia-Nia have reported cases with symptom onset only within the past week, suggesting more recent spread of the outbreak into new areas.
