NCDC also highlighted its response efforts, saying it had conducted a “high-level field mission to Bauchi State; activated the Incident Management System of the National Lassa Fever Emergency Operations Centre; analysed samples across the laboratory network to guide prompt diagnosis and treatment; and advocated for a budget line to support field activities for Lassa fever prevention and control”.

“Cumulatively, as at week five 2026, 31 deaths have been reported with a Case Fatality Rate (CFR) of 18.8 per cent, which is lower than the CFR for the same period in 2025 (19.6 per cent).

“In total for 2026, nine states have recorded at least one confirmed case across 33 local government areas.

“Ninety-two per cent of all confirmed Lassa fever cases were reported from five states (Bauchi, Ondo, Taraba, Edo, and Plateau), while eight per cent were reported from four states with confirmed Lassa fever cases.

“Of the 92 per cent confirmed cases, Bauchi reported 47 per cent, Ondo 18 per cent, Taraba 14 per cent, Edo eight per cent, and Plateau five per cent.
