Nigeria’s health authorities have raised fresh concerns over the worsening impact of Lassa fever after new figures showed that the disease has claimed 214 lives nationwide in 2026, with the fatality rate continuing to rise.
In its latest situation update released on June 22, the Nigeria Centre for Disease Control and Prevention (NCDC) said the Case Fatality Rate (CFR) has reached 25 per cent. The figure means one in every four confirmed infections has resulted in death this year.
The agency noted that although response measures remain active across affected states, current mortality levels are higher than those recorded during the same period in previous years, signalling ongoing challenges in containing severe outcomes.
According to the NCDC, delayed hospital visits, poor health-seeking behaviour and difficulties in managing advanced cases continue to contribute to the rising number of deaths.
“Lassa fever has claimed 214 lives in Nigeria, with the Case Fatality Rate rising to 25 per cent,” the agency stated in its update.
Health officials urged Nigerians to strengthen preventive practices, particularly maintaining proper environmental hygiene and reducing exposure to rodents, which are commonly associated with the spread of the disease. Residents were also advised to seek immediate medical attention whenever symptoms appear, as early treatment improves outcomes.
Lassa fever remains one of Nigeria’s recurring public health challenges, with outbreaks often placing pressure on health facilities and surveillance systems. The latest figures are expected to intensify awareness campaigns and public health interventions aimed at reducing infections and preventing further deaths.
