[Objective] To understand the incidence of viral hepatitis in Jiangyou and provide evidence for the development of viral hepatitis prevention and control measures. [Method] Descriptive analysis of viral hepatitis in Jiangyou from 2004 to 2008. [Results] A total of 9 380 cases of viral hepatitis were reported in Jiangyou from 2004 to 2008, with a prevalence of 213.20 / 100,000. The incidence showed an upward trend year by year, the incidence of the difference between each year was statistically significant (P <0.01). The incidence of male was higher than that of female, the difference was statistically significant (P <0.01). The type was mainly hepatitis B (8 838 cases), accounting for 94.22%; the season was higher in June-August (48.30% (4 052/9 380)); the age of onset was 10 months to 83 years Young adults (15-39 years old) dominated (7,833 cases), accounting for 83.51%.
