The Nigeria Centre for Disease Control and Prevention (NCDC) in its latest situation report says the country had recorded 811 confirmed cases of Lassa Fever and 152 deaths this year.
Published on Monday, the Lassa Fever Situation Report for Week 28 (7th–13th July, 2025) that 11 new confirmed cases was reported in Ondo, Edo, and Benue States.
According to the NCDC, with respect to Lassa fever, “811 confirmed cases and 152 deaths recorded cumulatively in 2025. Case Fatality Rate (CFR) is 18.7%, higher than the 17.3% reported same period in 2024. 89% of confirmed cases are from five states: Ondo, Bauchi, Edo, Taraba, and Ebonyi”.
The agency further disclosed that in total for 2025, 21 states recorded at least one confirmed case across 105 Local Government Areas.
Also, in week 28, the number of new confirmed cases was the same as epi week 27 of 2025.
In response, the NCDC implemented Lassa fever Environmental response campaign in high-burden states. It however lamented that late presentation of cases was leading to an increase in fatality rate.
It added that, poor health-seeking behaviour due to the high cost of treatment and clinical management of Lassa fever, poor environmental sanitation conditions observed in high-burden communities and poor awareness were observed in high-burden communities.
The NCDC therefore urged the public to report suspected cases of individuals presenting with malaise, fever, headache, sore throat, cough, nausea, vomiting, diarrhoea, myalgia, chest pain and hearing loss.
