The Nigeria Centre for Disease Control and Prevention (NCDC) has emphasised the growing urgency for Nigerians to maintain rodent-free environments and enhance personal hygiene amid the ongoing Lassa fever outbreak.
With the disease spreading and already claiming 98 lives in 2025, including a medical doctor, the agency stressed the need for preventive measures such as proper waste disposal, sealing food in airtight containers, and blocking rodent entry points.
The agency’s Director General (DG), Jide Idris, said that the public health advisory became necessary due to the alarming case fatality rate of 18.3% as of epidemiological week 9 (February 24 – March 2, 2025).
During the period, he said the 98 deaths were recorded across 14 States, including that of a health worker, a physician.
Breaking down the figures, the DG revealed that as of the period under review, Nigeria has recorded 2,728 suspected cases and 535 confirmed cases.
He said Ondo, Bauchi, Edo, Taraba, and Ebonyi States accounted for 91% of confirmed cases, while 10 Local Government Areas (LGAs) contributed 68% of the total cases.
Providing details on the physician’s case, Idris said the agency was notified of a confirmed Lassa fever infection in a 31-year-old physician who had recently returned from the United Kingdom.
“On the 5th of March 2025, the Nigeria Centre for Disease Control and Prevention (NCDC) was notified of a confirmed case of Lassa fever by the Ondo State Ministry of Health, in a 31-year-old physician managed at a private health facility in Ondo State after returning from a trip abroad (UK).
“The patient departed Nigeria on 19/02/2025 and returned on 27/02/2025. Samples were taken late on Friday, 28/02/2025, on suspicion of Lassa fever, but the patient unfortunately passed away in the early hours of Saturday, 01/03/2025.
“The laboratory investigation result returned was a Lassa Fever positive on PCR on Tuesday 04/03/2025.
“The patient was said to have visited his fiancée in Edo state, as well as family and friends before travelling,” he said.
The DG assured that to contain the outbreak, the Ondo State Ministry of Health has intensified contact tracing and monitoring of all possible contacts.
He also noted that national health authorities have mobilised response efforts, including surveillance at points of entry and coordination with international health agencies.
