Ebola (Bundibugyo) — regional outbreak in DRC; Liberia point-of-entry screening and monitoring
A large Ebola outbreak caused by Bundibugyo virus in the Democratic Republic of the Congo during 2026 prompted neighbouring and regional states to increase point‑of‑entry screening, traveller monitoring and preparedness activities.

New Era Inquirer (NPHIL statement, 2 Sep 2026) and domestic reporting on border and port assessments. The Liberian Post (report on NPHIL preparedness, 3 Oct 2026). Why it matters to travellers: screening measures (temperature checks, symptom questionnaires, and 21‑day follow‑up or travel restrictions applied by some destination/transit countries) may affect travel plans if you have recently been in DRC; always check the latest airline and destination entry rules before travel.
Animal bites and rabies exposure — increased reporting of bites and program response
Liberian authorities and partners have highlighted a high number of animal-bite incidents in 2026 and have described ongoing response actions including awareness and collaboration with veterinary/public‑health sectors; one report noted thousands of bite events and several deaths linked to rabies exposure.
