The Nigeria Centre for Disease Control and Prevention (NCDC), has reported 80 deaths from 413 confirmed Lassa fever cases across 11 states during Epidemiological Week 6 (Feb. 3–9, 2025).
The NCDC disclosed this on its website, noting that the case fatality rate (CFR) had risen to 19.4 per cent, up from 17.5 per cent in the same period in 2024.
The latest Lassa Fever Situation Report revealed that 73 per cent of confirmed cases came from Ondo, Edo, and Bauchi states, with Ondo leading at 34 per cent, followed by Edo 21 per cent and Bauchi 18 per cent.
It said a total of 63 local government areas in these 11 states had recorded confirmed cases.
The NCDC said while no new healthcare worker infections were reported, delayed case presentations had contributed to the rising fatality rate.
The NCDC pointed to poor health-seeking behaviour, high treatment costs, and limited awareness in high-burden communities as major challenges.
To address the outbreak, the NCDC had activated the National Lassa Fever Multi-Sectoral Incident Management System (IMS) to coordinate efforts.
The NCDC stated that it was also collaborating with the World Health Organisation (WHO), Médecins Sans Frontières (MSF), and the International Research Centre of Excellence (IRCE) to improve diagnosis, treatment, and outbreak response.
The agency urged Nigerians to take preventive measures, including maintaining proper hygiene, avoiding contact with rodent droppings, and seeking medical attention early if symptoms like fever, sore throat, and unexplained bleeding occur.
The NCDC further urged Nigerians to reduce their risk of infection by following these measures: store food properly in sealed containers to prevent rat contamination.
The NCDC stated that Lassa fever is preventable and encouraged Nigerians to stay informed and take action to protect themselves and their loved ones.
