Objective To analyze the epidemiological characteristics of viral hepatitis in Gaoyou and explore the control strategies. Methods Descriptive epidemiological methods were used to analyze the epidemic data of viral hepatitis in Gaoyou from 2004 to 2013. Results The average annual incidence of viral hepatitis between 2004 and 2013 was 37.68 / 100000 (23.64 / 100000 ~ 57.77 / 100000), and the overall incidence of viral hepatitis showed a decreasing trend in 10 years. Incidence of hepatitis A and hepatitis B showed a downward trend, the incidence of hepatitis C and hepatitis E showed an upward trend. There was no significant difference in seasonal distribution of viral hepatitis. The age at onset was 35-59 years old, with a sex ratio of 2.93: 1. The proportions of A, B, C, E and non-segmented hepatitis were 11.71%, 41.79%, 10.07%, 23.94% and 12.49%, respectively. Conclusion Immunization is an effective method for hepatitis A and hepatitis B. At the same time, monitoring and prevention of hepatitis C and hepatitis E should be strengthened.
