Lassa fever cases continue to rise in Nigeria.

Nigeria is currently experiencing a large outbreak of Lassa fever, with 4702 suspected cases, five probable cases, and 877 confirmed cases between epidemiological weeks 1 and 15 of 2023. Among confirmed cases, there have been 152 deaths. Responding to the current outbreak is challenging due to the need to respond to multiple emergencies simultaneously. Prevention of Lassa fever requires the promotion of good community hygiene to prevent rodents from entering homes. Effective measures include storing grain and other food in rodent-proof containers, disposing of garbage away from homes, keeping homes clean, and keeping cats in the home.
