The Nigeria Centre for Disease Control and Prevention (NCDC) has confirmed that Lassa fever has claimed 152 lives across Nigeria in the first 28 weeks of 2025, highlighting a rise in the disease’s deadliness despite a slight drop in confirmed infections.
The Nation reported that this marks a higher case fatality rate (CFR) of 18.7 per cent, compared to 17.3 per cent within the same period in 2024.
The latest situation report released yesterday in Abuja by the NCDC via its official website said the nation had recorded 811 confirmed cases and over 6,520 suspected infections so far.
The public health agency explained that these span 21 states and 105 local government areas, with the highest burden concentrated in Ondo, Bauchi, Edo, Taraba, and Ebonyi states
“We are witnessing a slight decline in the total number of confirmed cases, compared to 2024, but the fatality rate has increased,” it said.
NCDC also indicated possible late presentation, poor health-seeking behaviour, and limited access to early treatment as contributing factors.
The agency noted that in epidemiological week 28 alone, 11 new confirmed cases and one death were recorded, with reported infections from Ondo, Edo, and Benue states.
The agency said no healthcare workers were affected during the week.
It added that individuals aged between 21 and 30 years remained the most affected age group, with a nearly equal male-to-female distribution of cases.
The NCDC has ramped up its response to the Lassa fever outbreak in the worst-hit areas, working closely with partners to limit the spread and improve patient care.
Reports revealed that ten rapid response teams have been deployed to priority states using a combined health strategy focused on humans, animals, and the environment.
In Ondo State, clinical trials are underway to enhance treatment and case management efforts.
Healthcare workers in Bauchi, Ebonyi, and Benue have also received specialised training to better handle the rising infections.
