ABSTRACT
Introduction: Leptospirosis is a zoonotic disease caused by Leptospira interrogans and has been reported from various countries worldwide. As very few studies were conducted on leptospirosis from north India, this study was conducted to know the status of this disease in this region. This retrospective hospital Material & Methods: based study was conducted in the Department of Microbiology of a tertiary care super specialty teaching institute from north India for a period of two consecutive years. Blood specimens from acute febrile illness cases were tested for presence of IgM antibodies against Leptospira interrogans by rapid card (Leptocheck from TULIP) testing and ELISA (Leptospira IgM ELISA from PanBio). Out of total 216 samples Results: collected and included in this study, 40 were found to be positive for presence of IgM antibodies against Leptospira interrogans. Seropositivity for leptospirosis was observed to be 19%. Maximum number of patients were from economically productive age groups, 31-40 years of age group followed by 21-30 and 41-50 years of age groups. CONCLUSION: Leptospirosis was found to be a major cause of acute febrile illness from north India. It is neglected and under reported from most of the regions of India due to lack of clinician's suspicion. More studies with more samples are required on leptospirosis from this region to reach on final conclusion.
