Abstract：Objective To analyze the epidemiological features of viral hepatitis in Xinjiang Production and Construction Corps, and to provide a scientific basis for the adjustment of hepatitis prevention and control strategies. Methods Data about viral hepatitis epidemic in Xinjiang Production and Construction Corps from 2010 to 2021 were collected, and the epidemiological characteristics of viral hepatitis were analyzed using descriptive epidemiological methods. Results A total of 40,680 cases and 48 deaths were reported in Xinjiang Production and Construction Corps from 2010 to 2021, with an average annual morbidity of 119.4/100,000, showing an overall downward trend. Hepatitis B accounted for the highest proportion (73.21%, 29,780/40,680), followed by hepatitis C (22.13%, 9,001/40,680). Cases were reported in all regions, with the eighth division (11,231 cases), the first division (5,828 cases) and the seventh division (4,765 cases) topping the list. The age group with the largest number of cases was >45-50 years (6,393 cases), followed by >50-55 years (5,195 cases) and >40-45 years (4,850 cases). In occupational composition, most of the cases were farmers (accounting for 24.54%). Conclusion In recent years, the incidence rate of viral hepatitis in Xinjiang Production and Construction Corps has been decreasing year by year, but the overall incidence rate is still at a high level. Preventive vaccination against hepatitis A and B among the key groups should be further enhanced, while targeted comprehensive measures against hepatitis C and E infection like strengthening food safety supervision, intensifying disinfection and isolation in hospitals, and strengthening dynamic monitoring of the epidemic should be taken.
