*Detected by IgM-capture ELISA in serum samples submitted to Lassa Diagnostic Laboratory (Kenema, Sierra Leon) for suspected Lassa fever. All samples tested were malaria negative by thick blood smear and Lassa virus negative by antigen detection and IgM-capture ELISA when initially tested. Samples with sufficient volumes were tested for the presence of IgG to determine samples that were IgM positive only.
