The Nigeria Centre for Disease Control and Prevention said Lassa fever claimed 138 lives between January till date with a 19.3 per cent case fatality rate.
This is according to the NCDC latest situation report shared via its official website.
The report noted the figure is a rise from the 18.0 per cent recorded within the same period in 2024.
The report added that a total of 717 confirmed cases were recorded as of Epi Week 18, with four new states (Ondo, Edo, Bauchi, and Benue) reporting cases in the current week alone.
The public health agency said that while the number of new confirmed cases slightly decreased from 11 to 10 in the past week, the overall death toll remained alarming.
The report noted that 71 per cent of all confirmed cases originated from three states: Ondo, 30 per cent, Bauchi, 25 per cent and Taraba, 16 per cent signalling persistent hotspots despite nationwide interventions.
It added that the most affected age group was 21–30 years, with the male gender appearing slightly more affected than the female with a male-to-female ratio of 1:0.8.
The agency however said that no healthcare worker was infected in the current week, though 22 healthcare workers have been affected so far this year.
The report disclosed that the NCDC activated a multi-partner, multi-sectoral Incident Management System and deployed 10 Rapid Response Teams across affected states.
It said that the agency also intensified contact tracing, community sensitisation, and distributed essential commodities such as PPES, Ribavirin, body bags, and disinfectants.
This it said is in collaboration with international partners such as the WHO, MSF, CEPI, and Georgetown University.
The country conducted multiple webinars, capacity-building training, and surveillance activities to combat the outbreak.
However, the public health agency described that challenges to the responses were hampered by late presentation of cases, poor health-seeking behaviour, and low awareness levels in high-burden areas.
It also said that poor environmental sanitation contributed to disease spread.
The agency continues to urge Nigerians to maintain hygiene, report symptoms early, and avoid contact with rodents and their secretions.
It said, “The public is also encouraged to follow NCDC advisories and utilise the toll-free line 6232 for inquiries.’’
Lassa fever is a viral haemorrhagic disease transmitted primarily through contact with the urine or faeces of infected rats. It can also spread from person to person through bodily fluids, contaminated objects, or infected medical equipment.
Symptoms include fever, sore throat, headache, vomiting, muscle pain, and in severe cases, bleeding from body openings.
