Nigeria Lassa Fever Toll Escalates As NCDC Reports 822 Cases, 155 Deaths
written by Chioma Umeha August 5, 2025

CFR Hits 18.9 percent, Ondo, Edo Bear Brunt of Outbreak

Nigeria’s Lassa Fever toll has soared, with the Nigeria Centre for Disease Control and Prevention reporting 822 confirmed cases and 155 deaths, signalling a deepening national health crisis.

NCDC on Tuesday, confirmed 11 additional cases of Lassa Fever in Week 29 (14–20 July 2025), all reported in Ondo and Edo States.

This latest surge brings the national total to 822 confirmed cases and a grim tally of 155 deaths so far in 2025. The announcement underlines a deteriorating situation that demands urgent, coordinated interventions at every level of government and healthcare delivery.

NCDC’s Situation Report reveals a Case Fatality Rate (CFR) of 18.9 percent – an increase from the 17.1 percent recorded at the same point in 2024. This uptick is especially troubling given that the number of new confirmed infections remained steady compared with Epidemiological Week 28, suggesting that the deadliness of Lassa Fever may be intensifying rather than the incidence alone driving mortality...
