Confirmed cases stand at 920, resulting in 162 fatalities and a case fatality rate of 17.6%. This rate is lower than the 20% recorded during the same period in 2023.

Lassa fever, a viral hemorrhagic illness caused by the Lassa virus, is commonly transmitted through exposure to contaminated food or household items. The disease is endemic in West Africa, and person-to-person infections can occur in healthcare settings with inadequate infection prevention measures.
