Abstract
Objective:To analyze the epidemiological characteristics of hepatitis B in the central urban area of Jiujiang City from 2019 to 2023 and the hepatitis B vaccination status of infants born to mothers positive for hepatitis B surface antigen(HBsAg)from 2021 to 2023,and to provide a basis for the targeted formulation of prevention and control measures.Methods:The annual reported incidence rate and annual reported cases of hepatitis B in the central urban area of Jiujiang City from 2019 to 2023 were derived from the Chinese disease prevention and control information system.The vaccination status of infants born to HBsAg-positive mothers from 2021 to 2023 in Maternity Hospital of Jiujiang central urban area was queried through the Jiangxi Provincial immunization planning information system,and descriptive epidemiological methods were used for statistical analysis.Results:From 2019 to 2023,the annual reported incidence rate of hepatitis B in Jiujiang central urban area showed an upward trend,with an annual average of 156.30/100 000.A total of 3 404 cases were reported,with a male-to-female ratio of 1.59∶1.Among the reported cases,individuals aged 20 to 69 accounted for 91.16%.The main occupations were unemployment,retired people,farmers,and public service personnel(85.40%),which were mainly distributed in Renmin Road,Gantang Street,Xiangyang Street,Binxing Street,and Baishuihu Street(77.26%).The first dose of hepatitis B vaccine for infants born to HBsAg positive mothers was 99.63%,and the timely rate was 95.69%.Conclusion:In the past five years,the incidence rate of hepatitis B reported in the central urban area of Jiujiang City is relatively high,and it is on the rise,mainly for adult males;the vaccination rate and timely rate of hepatitis B vaccine for infants born to HBsAg positive mothers are high.It is necessary to continue to carry out maternal and infant immunization blocking measures,carry out research on hepatitis B risk factors,and strengthen the prevention and control measures for adults with hepatitis B,so as to reduce the incidence of hepatitis B in the whole population.关键词
