Comparative Study
Screening of patients with acute febrile illness for leptospirosis using clinical criteria and serology.
Leptospirosis is one of the common zoonoses but, in most instances, the infection goes unnoticed. Rapid diagnostic modalities are needed to diagnose the disease in the early stages. We assessed the usefulness of clinical criteria and compared these with enzyme-linked immunosorbentassay (ELISA) for the early detection of leptospirosis. ⋯ Faine criteria has moderate sensitivity and specificity but a high negative predictive value in comparison with IgM ELISA. The high negative predictive value may help to screen patients with acute febrile illness for leptospirosis during the early phase of the disease.
