Lassa fever claims 127 lives in Nigeria amid rising cases​

NIGERIA – The Nigeria Centre for Disease Control and Prevention (NCDC) has reported that Lassa fever has resulted in 127 deaths across 18 states between January and April 2025.

This marks a case fatality rate (CFR) of 18.8%, slightly higher than the 18.5% recorded during the same period in 2024. ​

The outbreak has been most severe in Ondo, Bauchi, and Edo states, which together account for over 70% of confirmed cases.

Specifically, Ondo reported 30%, Bauchi 25%, and Edo 16% of the total cases. In the latest reporting week, 15 new cases emerged from six states: Ondo, Bauchi, Edo, Taraba, Ebonyi, and Gombe. ​

The NCDC has activated its multi-sectoral Incident Management System to coordinate response efforts at all levels.

The agency emphasizes the importance of early detection and treatment, as well as maintaining proper hygiene and sanitation to prevent the spread of the disease. ​

Lassa fever is an acute viral hemorrhagic illness transmitted to humans through contact with food or household items contaminated with rodent urine or feces.

Human-to-human transmission can also occur, particularly in healthcare settings without adequate infection control measures. ​

The NCDC advises the public to avoid contact with rodents, maintain clean environments, and seek medical attention promptly if symptoms such as fever, sore throat, vomiting, or bleeding occur.

Healthcare workers are urged to adhere strictly to standard precautions to prevent nosocomial infections. ​

Efforts are ongoing to enhance surveillance, laboratory capacity, and public awareness to curb the spread of Lassa fever in Nigeria.

The NCDC continues to collaborate with state health authorities and international partners to strengthen the country’s response to the outbreak.
