The agency said 215 deaths were recorded from Lassa fever last year, representing an 18.7 per cent increase compared with 2024 figures.

In a statement published on its official website, the NCDC said the rise was troubling but noted that it had intensified surveillance, testing and response efforts to prevent further spread.

“In week 52 alone, 27 new confirmed cases and nine deaths were reported across Bauchi, Ondo, Ebonyi, Taraba and Nasarawa states,” the agency said.

Ondo State accounted for 35 per cent of confirmed cases, followed by Bauchi with 26 per cent, Edo with 16 per cent and Taraba with 12 per cent, according to the data.

The NCDC said it was working closely with state health authorities to strengthen early detection, case management and community awareness, particularly in high-burden states.

Health officials urged Nigerians to maintain hygiene, avoid contact with rodents and seek immediate medical attention if they experience symptoms such as fever, bleeding, vomiting or weakness.

Lassa fever is an acute viral haemorrhagic illness endemic in parts of Nigeria and is transmitted primarily through contact with food or household items contaminated by rodent urine or faeces, as well as through person-to-person contact in healthcare settings.
