Nigeria’s health agency, the Nigeria Centre for Disease Control and Prevention (NCDC), reports 1,138 confirmed Lassa fever cases and 268 deaths across 24 states. The NCDC says the case fatality rate is 23.6%. The figures reflect the national burden of the disease as captured in its latest situation reporting.
Outlets also note that the most recent NCDC update covers the period from September 28 to October 4 (epidemiological week 40 of 2026). While newly confirmed infections decline in the latest reporting week, overall deaths remain high. The reporting varies slightly in emphasis—some outlets foreground the nationwide totals, while another stresses the rise in the fatality rate alongside the drop in new cases—but all cite the same NCDC statistics and geographic coverage.
No source provides additional details on individual outbreaks, testing capacity, or changes in clinical management beyond the headline case and mortality figures.
