The NCDC blamed delayed treatment and poor health-seeking behaviour for the rising number of deaths across affected communities.
“We are seeing late presentation of cases in many communities, and this continues to drive preventable deaths. The high fatality rate is a clear signal that people are arriving at treatment centres too late,” the agency stated.
Although suspected cases have dropped, confirmed infections continue to rise in several states. Health officials warned that the current fatality rate remains dangerously high.
“Lassa fever is treatable when detected early, but we are still losing too many lives because patients come in late,” the NCDC added.
To contain the outbreak, the agency announced it has activated a nationwide multi-partner Incident Management System to strengthen response efforts across the country.

The intervention includes infection prevention training for healthcare workers in Ondo and Ebonyi states, deployment of rapid response teams to high-risk communities, and distribution of personal protective equipment to treatment centres.
Notably, the NCDC stated it has expanded public awareness campaigns and improved disease surveillance with support from the WHO, UNICEF, Centers for Disease Control and Prevention, Médecins Sans Frontières, ALIMA and RTI International.
The agency urged residents to improve environmental sanitation and intensify rodent control measures to limit the spread of the disease in homes and communities.
“All stakeholders must sustain community engagement and strengthen infection prevention practices in both health facilities and households,” the report advised.
Public health experts continue to stress the importance of early diagnosis and prompt treatment to reduce deaths linked to the ongoing outbreak.
