    Lassa fever mortality in Nigeria persists due to delayed recognition, limited diagnostic access, and constrained supportive care rather than viral evolution.

  • 2

    Patients often present late with severe complications after being treated for other illnesses, highlighting the need for early diagnosis and intervention.

  • 3

    Diagnostic challenges arise from the overlap of Lassa fever symptoms with other common febrile illnesses, delaying appropriate treatment.

  • 4

    Health system limitations, including inadequate isolation units and insufficient resources, significantly increase mortality risk in severe cases.

  • 5

    Reframing the narrative from viral mutation to systemic clinical determinants can help focus on actionable solutions to reduce Lassa fever deaths.
