The Nigeria Centre for Disease Control and Prevention (NCDC) has confirmed 13 new cases of Lassa fever in the 40th epidemiological week, covering September 29 to October 5, 2025.
According to the agency’s latest situation report, shared via its official X (formerly Twitter) handle, the new infections were detected in Ondo and Edo States, two of the hardest-hit areas since the start of the year.
With the latest figures, Nigeria has now recorded a total of 924 confirmed cases and 172 deaths across 21 states and 106 Local Government Areas (LGAs) in 2025. The Case Fatality Rate (CFR) currently stands at 18.6 percent, up from 17.0 percent reported during the same period in 2024.
During the week under review, 117 new suspected cases were reported, bringing the cumulative total of suspected cases for the year to 8,041.
The NCDC noted that over 90 percent of all confirmed cases this year have come from Ondo, Bauchi, Edo, Taraba, and Ebonyi States, which remain the epicenters of the outbreak.
Reaffirming its commitment to halting the spread, the Centre said it is intensifying efforts in surveillance, laboratory testing, risk communication, and infection prevention and control nationwide.
Health authorities urged Nigerians to adopt preventive measures, including maintaining clean environments, avoiding contact with rodents, and storing food properly to minimize the risk of infection.
They also advised individuals experiencing symptoms such as persistent fever, sore throat, chest pain, or vomiting to report immediately to the nearest health facility for prompt diagnosis and treatment.
The NCDC emphasized that it continues to work closely with state ministries of health, development partners, and community stakeholders to ensure an effective response and quality care for affected persons.
