abstract
The present study was conducted to find out the clinico-epidemiological profile of the AES (Non JE and JE) during its outbreaks from the year 2014 to 2016 in tertiary care centre, Tezpur (Assam). It was a retrospective study. The AES cases were initially tested for antibodies against JE by using IgM Mac ELISA (National Institute of Virology, Pune). Out of 553 AES cases, 12 patients excluded as death occurred. A total of 541 sera samples from the patients clinically suspected with acute encephalitis syndrome (AES) were collected from the year 2014 to 2016. Out of which 54/541 (9.98%) were JE positive by IgM Mac ELISA kit, where 30/54 (55.56%) from male and 24/54(44.44%) was female. The remaining 487/541 (90.02%) patients were grouped as non JE AES. This study give the scenario of AES (Non JE and JE) in this part of the state and further efforts has to be done to find out the etiology of Non JE AES cases.
