Field Investigation of the Bundibugyo Ebola Virus Disease (BDBV) Outbreak in Ituri Province, Democratic Republic of the Congo: Challenges, Strategies, and Priority Actions for Outbreak Control—An Outbreak Investigation Review
Field investigation reveals high mortality and containment barriers in conflict-affected Congolese communities, highlighting the need for local trust and enhanced surveillance.
Key Points
Evaluate epidemiological patterns, operational bottlenecks, laboratory capacity, and community engagement challenges during the 2026 Bundibugyo Ebola virus disease outbreak in eastern Democratic Republic of the Congo.
Conducted a rapid field assessment between 12–15 June 2026 across Bunia, Rwampara Health Zone, and the Ituri Provincial Public Health Laboratory.
Evaluated surveillance metrics, laboratory reports, health facility operations, stakeholder interviews, and infodemic response systems.
Cumulative cases reached 1926 confirmed infections and 702 deaths (overall case fatality rate of 36.4%), with Ituri Province accounting for 90.8% of cases (1705/1877) and 85.5% of deaths (577/675).
Community deaths comprised 66.7% of daily mortalities (20/30), and contact tracing successfully monitored only 64.4% of registered contacts (4171/6475), falling well short of the ≥95% benchmark.
Diagnostic laboratory testing achieved a 21.2% positivity rate (29/137), but response efforts faced severe constraints including treatment center overcrowding, staff shortages, and community resistance.
