Case Fatality Rate and Contributing Factors
The case fatality rate has increased to over 23 percent from just under 19 percent during the same period last year. Contributing factors include delayed treatment, inadequate sanitation, and low awareness in high-risk communities.
The NCDC is aiding local authorities through enhanced surveillance, contact tracing, and the deployment of rapid response teams in areas with high infection rates. Personal protective equipment is being supplied to healthcare facilities.

Individuals aged 21 to 30 are the most affected by Lassa fever. There is also a rise in infections among healthcare workers.
Lassa fever is part of the same virus family as Marburg and Ebola, known for causing fever, vomiting, and potentially hemorrhagic bleeding. The disease, named after the town of Lassa in northern Nigeria where it was first identified in 1969, is endemic to the region. It is asymptomatic in 80 percent of cases but can lead to internal bleeding if diagnosed late.
Currently, there are no licensed vaccines available for Lassa fever.
