This test-negative study is designed to evaluate the long-term effectiveness of hepatitis E vaccine (Hecolin®) and to explore the prevalence of rat hepatitis E in Dongtai City.
In this negative test study, residual clinical serum will be collected from 13 hospitals in Dongtai, if it was from patients born between 1941-1991 from 11 towns in Dongtai, who tested positive for ALT levels higher than 2.5 times the upper limit of normal (ULN). Detection of HEV IgM, IgG, antigen, RNA will be performed to diagnose hepatitis E (HE) in each individual. In addition, HE vaccination history will be collect. All the information above will be used to evaluate the long-term effectiveness of HE vaccine. Based on the study design, virological and serological detection (IgM, IgG, antigen, and RNA) of hepatitis E virus species C (HEV-C) will be performed to analyze the prevalence of rat hepatitis E infection in Dongtai.
