Trend of Japanese Encephalitis in Rural Areas of West Bengal, India: *A Retrospective Study*
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 9
Abstract
The present study was conducted to find out the clinico-epidemiological profile of Japanese encephalitis (JE) during the year 2013 to 2018 (till June) in a tertiary care teaching hospital, MMC, Malda, West Bengal. It was a retrospective study. The AES (Acute Encephalitis Syndrome) cases were tested for IgM antibodies against JE virus by using IgM Mac ELISA (National Institute of Virology, Pune). A total of 293 sera samples from the patients clinically suspected with AES were collected from the year 2013 to 2018 (till June). Out of which 30/293 (10.24%) were JE positive by IgM Mac ELISA kit, where 19 (63.33%) were male and rest 11 (36.67%) were female. Maximum number of JE cases was reported in the age group 0-15 yrs (63.33%: 40% in the age group of less than 5 years and 23.33% in the age group of 5-15 years). Death occurred in 6/30 (20%) patients. The present study showed a low JE seropositivity in this region of northern part of West Bengal. As most JE infections are asymptomatic, the cases of JE may not represent the original scenario of JE in this northern part of West Bengal, may only represent the tip of the iceberg compared to the large number of inapparent infections. So JE surveillance system and the vaccination programme need to be strengthened to keep this vector borne disease under control.
