Objective To understand the distinction of the epidemic characteristics of hepatitis A and E. Methods Local data of hepatitis A and E were analyzed. Result The incidence rate of hepatitis A declined while that of E increased year by year. The incidence rate of hepatitis A in group 20～45 years old is high, and that of E is high in age group 50～75. Conclusion The reason that hepatitis A incidence rate declines may be due to vaccine inoculation. It is estimated that the incidence rate of hepatitis A would keep on declining and that of hepatitis E rises continuously in Suzhou.
