Lassa fever transmission is now observed year-round, not just in dry seasons
Lassa fever cases are surging again across Nigeria, with the Nigeria Centre for Disease Control and Prevention (NCDC) confirming increased infections and a higher fatality rate despite ongoing interventions.
In its Week 22 Situation Report (May 26–June 1), the NCDC confirmed eight new cases in Ondo, Bauchi, Edo, and Nasarawa, bringing 2025’s total to 747 confirmed infections and 142 deaths—a 19.0% case fatality rate, up from 18.1% in 2024.
Eighteen states and 96 LGAs are affected, with five states—Ondo, Bauchi, Edo, Taraba, and Ebonyi—accounting for 91% of cases.
“No new infections among healthcare workers” were reported, but delayed case presentation, poor sanitation, and low health-seeking behaviour remain key barriers.
Dr Solomon Chollom said, “We can’t fight Lassa with hospital efforts alone… the communities must be empowered.”
The NCDC is intensifying response efforts with rapid response teams, health worker training, and community sensitisation
