Abstract：Objective To learn the epidemiological characteristics of acute hepatitis B in Jiangxi Province from 2014 to 2021, so as to provide insights into perfecting hepatitis B prevention and control strategy. Methods Data pertaining to acute hepatitis B was collected through the Chinese Disease Prevention and Control Information System. The temporal, spatial and population distributions of acute hepatitis B were analyzed using a descriptive epidemiological method. The trend in incidence of acute hepatitis B was analyzed using annual percent change (APC). Results Totally 8 890 cases of acute hepatitis B were reported in Jiangxi Province from 2014 to 2021, with the reported incidence showing a tendency towards a decline (APC=-11.730%, P<0.05). The average annual reported incidence rate of acute hepatitis B was 2.42/105. Acute hepatitis B occurred all the year round, without obvious seasonal characteristics. The top three highest incidence rates were reported in Pingxiang City (7.12/105), Ganzhou City (3.12/105) and Fuzhou City (2.87/105). The lowest and highest incidence rates of acute hepatitis B were seen among residents aged under 10 years (0.30/105) and 20-29 years (3.86/105). The incidence rate of males was higher than that of females (3.25/105 vs. 1.55/105, P<0.05). Farmers were predominant population affected acute hepatitis B (5 764 cases, 64.84%). Conclusions The incidence of acute hepatitis B showed a downward trend in Jiangxi Province from 2014 to 2021, and the disease predominantly affected young males, farmers. Health education should be strengthened, and hepatitis B vaccination coverage should be promoted.
