Abstract：Objective To analyze the epidemiological features of viral hepatitis in Futian District of Shenzhen City so as to provide a basis for adopting targeted prevention and control measures. Methods Descriptive epidemiological method was used to analyze the data concerning viral hepatitis cases reported by the Notifiable Disease Reporting System of Futian District, Shenzhen City during 1985-2015. Results A total of 17,968 cases of viral hepatitis were reported accumulatively in Futian District, Shenzhen City during 1985-2015, with an average annual incidence rate of 90.9/100,000. The incidence rate was the highest in 1987 (223.7/100,000). The incidence rates of hepatitis A and acute hepatitis B had decreased gradually since 1990 and 1991 respectively. However, the number of chronic hepatitis B cases had been keeping fluctuating at a high level. The incidence rates of hepatitis C and AIDS had showed the same rising tendency since 2004. The incidence rate of hepatitis E had remained stable since 1996. Hepatitis A showed a seasonal peak in spring (from March to May) during 1989- 1993. No obvious seasonal distribution was found in other hepatitis. Males had higher incidence rates in each type of viral hepatitis. The peak age for onset of hepatitis B was 20-< 30 years, while the peak age for onset of hepatitis A, C and E was all 30-<40 years. The cases of hepatitis A (during 1989-2005) and hepatitis B (during 1989-2008) were mainly workers and students, and then homemakers and commercial staff became the main source. No obvious occupational distribution features were observed in hepatitis C and E. Conclusions The epidemics of viral hepatitis occurred in Futian District around the year 1990, with hepatitis A and B as the main types. Currently, the incidence rates of hepatitis A, acute hepatitis B and hepatitis E are all low, but the number of chronic hepatitis B cases is large. The incidence rate of hepatitis C presents a rapidly rising trend. Targeted and comprehensive prevention and control measures should be taken to curb the epidemics of hepatitis B and C in Futian District.
