DOI: htps://doi.org/10.24321/0019.5138.202035 Introducton: Japanese Encephalits (JE), a leading cause of AES is a vector-borne disease is caused by the JE virus belonging to the genus Flavivirus (Flaviviridae family), and transmited by bite of Culex vishnui subgroup tritaeniorhynchus, the most important reported vector species for JE transmission in India. Methodology: A study was conducted on 1131 AES suspected cases in JE laboratory of Centre for Arboviral and Zoonotc diseases, Natonal Centre for Disease Control (NCDC), Delhi from tertary care referral hospitals of Delhi for laboratory confrmaton of JE during the period from January 2017- December 2019. CSF and/ or Serum Samples from 1131 hospitalized AES suspected cases mostly from Delhi, UP, Haryana addresses. They were tested and interpreted for IgM antbodies by the JE IgM Capture ELISA kit (Natonal Insttute of Virology, Pune). The demographic profle (age/ sex/ seasonality/ place) of JE confrmed cases were analyzed. Result: 77 (6.8%) out of 1131 AES suspected cases were JE confrmed. 48 patents (62.2%) were of pediatric age group 19 (24.7%) were of middle age adult and 10 (13.0 %) were older age adults out of 77 JE confrmed cases.. The JE cases occurred throughout the year, though maximum cases were observed in the monsoon seasons (June-October) in our study. In our study most of the JE confrmed patents were residents of state of Delhi, Utar Pradesh and Haryana. Conclusion: The study atempts to highlight the need of strengthening quality of laboratory detecton of JE in AES cases, need for intensive vector control policy and re-evaluaton of the policy of JE vaccinaton in India.
