Over 200 Nigerians Die from Lassa Fever in 2025, Concerns Raised Over High Fatality Rate

In 2025, Nigeria recorded over 200 deaths from Lassa fever, with a high Case Fatality Rate (CFR) due to late presentation, poor health-seeking behavior, and expensive treatment costs, especially in heavily affected communities. The NCDC highlighted the concerning concentration of confirmed cases in just four states: Ondo, Bauchi, Edo, and Taraba.

Lassa fever, caused by a virus transmitted through contact with infected rodents, poses a significant health challenge in Nigeria. The government emphasizes routine infection prevention measures and early detection for effective control.

The history of Lassa fever in Nigeria dates back to its first diagnosis in a village in Borno State in 1969.
