Abstract
Introduction
Acute encephalitis syndrome (AES) is caused by a wide range of viruses and bacteria[1]. Japanese encephalitis (JE) is considered as a main viral etiology of patients with AES in Assam[2]. Leptospirosis is primarily a zoonosis, with humans serving as accidental hosts. Leptospirosis is a zoonosis which in its milder form resembles any other viral illness and in its severe form needs to be differentiated from other common infectionin tropical regions of India like viral encephalitis, scrubtyphus, dengue, malaria, viral hepatitis, and Hantavirus Infection. Most cases of human leptospirosis worldwide have been attributed to rodents. Human leptospiral infection primarily resulted from direct or indirect exposure to the urine of infected animals. . Leptospira organisms can survive for a long period in natural aqueous environments[3]. .Leptospira is a thin spiral organism with tightly set coils, and it is characterized by very active motility, by rotating (“spinning”) and bending. Usually one or both ends of this single-cell organism are bent or hooked, but straight forms also occur that rotate and travel more slowly than hooked forms .Agricultural workers are most infected during cultivated rice activity in marshy land[4] or capturing fish or animals.
