Key result
BEACON event-based surveillance detects 4 unresolved VHF-compatible illness signals preceding the Bundibugyo virus outbreak.
Why the study?
The May 2026 Bundibugyo virus disease outbreak in the DRC was declared a Public Health Emergency of International Concern after substantial undetected community transmission, prompting description of preceding regional surveillance signals.

Detection of unresolved VHF signals preceding the confirmed BDBV outbreak highlights gaps in formal follow-up mechanisms and regional diagnostic coordination.
Bhadelia et al. (2026) conducted an observational in Bundibugyo virus disease (BVD) / Viral Hemorrhagic Fever (VHF). Event-based surveillance (BEACON) was evaluated on Detection of VHF-compatible illness signals preceding the BDBV outbreak. Event-based surveillance using BEACON detected 4 unresolved VHF-compatible illness signals in the DRC-Uganda-Burundi-South Sudan region preceding the May 2026 Bundibugyo virus disease outbreak.
