Nigeria’s Lassa fever death toll has risen to 263, with the case fatality rate climbing to 23.6 per cent from 18.5 per cent recorded during the corresponding period in 2025.
The Nigeria Centre for Disease Control and Prevention (NCDC) disclosed this in its situation report for epidemiological week 38, covering September 14 to 20, 2026.
According to the report, the country has recorded 1,115 confirmed cases across 24 states and 119 Local Government Areas.
The latest figures represent an increase of four deaths and 11 confirmed cases from the previous week, when the agency reported 259 deaths and 1,104 confirmed infections.
Although new confirmed cases declined from 17 in week 37 to 11 in week 38, the NCDC said cumulative suspected and confirmed infections remained higher than those recorded during the corresponding period last year.
The 11 new confirmed cases were reported in Ondo, Edo and Taraba states.
Five states, Ondo, Bauchi, Taraba, Edo and Benue accounted for 87 per cent of confirmed infections recorded so far this year, highlighting the concentration of cases in a few states.
Ondo accounted for the largest share, at 35 per cent, followed by Bauchi with 23 per cent, Taraba with 12 per cent, Edo with 11 per cent and Benue with six per cent.
Other affected states accounted for the remaining 13 per cent.
The report showed that people aged 21 to 30 were the most affected age group.
However, confirmed patients ranged from one to 93 years old, with a median age of 30.
The male-to-female ratio among confirmed patients was 1:0.9.
No new infection was recorded among healthcare workers during the reporting week.
The NCDC stated that the National Lassa Fever Multisectoral Multi-partner Technical Working Group sustained its efforts to coordinate response activities across national, state and local government levels.
