Leptospirosis is one of the most widespread worldwide zoonotic occupational disease which is widely prevalent in various states of India, especially in Tamil Nadu. The mortality in severe disease ranges from 5-40%. Early diagnosis and treatment with appropriate antibiotics contributes to a reduction in the mortality rate. Hence this study was done with the objective of evaluating the usefulness of PCR in early diagnosis of human leptospirosis. Blood samples collected from patients with clinical diagnosis of leptospirosis during the first week of illness and blood samples from normal healthy controls were included in the study. | Evaluation of polymerase chain reaction in early diagnosis of leptospirosis
