More details
Cumulatively, Nigeria has recorded 290 confirmed cases of Lassa fever with 53 deaths in four weeks.
The number of deaths resulted in a case fatality rate (CFR) of 18.3 per cent which is lower than the CFR for the same period in 2024 which is 18.6 per cent.
While no health worker was affected in the reporting week, the NCDC stated that 10 states have recorded at least one confirmed case of Lassa fever across 54 local government areas between week one to four.
It said the predominant age group affected is 21-30 years.
NCDC noted that the National Lassa fever Multi-partner, Multi-sectoral Incident Management System has been activated to coordinate the response activities at all levels.
The centre also said it has deployed National Rapid Response Teams to support onsite control and management efforts using a One Health approach.
Challenges
NCDC, in the report, highlighted some of its challenges in the fight against Lassa fever.
The challenges include the late presentation of cases leading to an increase in CFR, and poor health-seeking behaviour due to the high cost of treatment and clinical management of Lassa fever.
