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 tenden-cy 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 in-cidence 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 hepa-titis B showed a downward trend in Jiangxi Provincefrom 2014 to 2021,and the disease predominantly affected young males,farmers.Health education should be strengthened,and hepatitis B vaccination coverage should be promoted.
