Nigeria records 145 Lassa fever deaths

The Nigeria Centre for Disease Control and Prevention (NCDC) has confirmed 145 deaths from Lassa fever in 2025, as the country continues to battle the viral hemorrhagic disease across 18 states.

According to the latest situation report released on Friday by the NCDC for epidemiological week 24 (June 9–15), the country recorded 766 confirmed cases from 5,678 suspected infections.

The case fatality rate stood at 18.9 per cent, up from 17.6 per cent during the same period in 2024.

The agency said that the states most affected were Ondo, Bauchi, Edo, Taraba, and Ebonyi, which accounted for 91 per cent of the confirmed cases.

It said that Ondo alone contributed 31 per cent making it the epicentre of the outbreak.

In spite a decline in new confirmed cases — down to eight from 11 the previous week — the Nigerian public health agency said that health authorities remained concerned about the high fatality rate.

The agency said that this was driven by late presentation of cases, poor health-seeking behaviour, and unsanitary living conditions in high-burden communities.

According to it, efforts to contain the outbreak have included the deployment of Rapid Response Teams to 10 states, risk communication, environmental sanitation campaigns, and training of health workers in high-risk areas.

The NCDC also de-escalated its Incident Management System to alert mode while integrating Lassa fever messages into wider disease awareness campaigns.

The agency has appealed to the public to avoid contact with rodents and to seek prompt medical care at designated treatment centres at the first sign of symptoms such as fever, headache, or bleeding.

The agency continues to urge Nigerians to maintain hygiene, report symptoms early, and avoid contact with rodents and their secretions.

“The public is also encouraged to follow NCDC advisories and utilise the toll-free line 6232 for inquiries,” it said.

Our correspondent reports that Lassa fever is a viral hemorrhagic 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 the body openings
