Introduction: Acute viral hepatitis (AVH) incidence had suddenly increased at Artillery Centre and School (AC&S) at Halishahore under Chattogram (Ctg) cantonment area from 16 April 2018 to 25 June 2018. Total 1304 cases of AVH got admitted and received treatment from Combined Military Hospital (CMH), Ctg during that period.
