Nigeria’s Lassa fever outbreak continues to worsen, with health authorities reporting that the death toll has risen to 191. Coverage of the outbreak, citing the Nigeria Centre for Disease Control (NCDC), states that new cases increase between surveillance weeks. One report notes that confirmed cases rise from nine in Week 17 to 22 in Week 18. Infections are reported across multiple states, including Ondo, Edo and Plateau, and another account says health authorities are tracking cases across many states and local government areas. Authorities also warn about an increasing fatality rate, attributing part of the risk to late treatment, which is described as worsening outcomes during the current period. One outlet compares the current situation with the same period in 2025, indicating that the reported fatality proportion is higher than previously recorded. Overall, the reports agree that deaths are at 191, while case counts and the situation’s severity are increasing, prompting continued public health monitoring and emphasis on timely care.
