Nigeria has reported 127 deaths and 674 confirmed cases of Lassa fever since January 2025. The outbreak has spread to 18 states, with Ondo, Edo, and Bauchi hardest hit.
Most cases are among young adults aged 21–30, with men more affected than women. The case fatality rate stands at 18.8/percent.
Lassa fever spreads through contact with rodent waste or infected bodily fluids. The NCDC has launched a nationwide response to contain the outbreak, but challenges like limited healthcare access and low public awareness persist.
