摘　　要：目的 了解2011—2020年杭州市拱墅区戊型病毒性肝炎(戊肝)的发病流行情况,为制定戊肝的防控措施提供依据。方法 从中国疾病预防控制信息系统收集2011—2020年拱墅区戊型病毒性肝炎病例报告数据,用描述性研究方法分析发病情况,用集中度值法进行季节性分析。结果 2011—2020年拱墅区报告戊肝452例,年均报告发病率为13.27/10万;男性年平均发病率(14.72/10万)高于女性(11.81/10万),差异有统计学意义(χ^(2)=5.402,P<0.05);发病职业以离退休人员、干部职员、工人为主;60岁及以上年龄段发病率最高(18.26/10万),随年龄上升,发病率逐渐升高(χ^(2)=7.71,P<0.05);时间分布上发病总体呈波浪型趋势,无明显季节性。结论 拱墅区戊肝发病呈波浪形特征,发病率较高,以中老年人群为主,应重视戊肝防制工作,加强健康宣教、食品监管工作,推广重点人员疫苗接种。Objective To investigate the incidence and prevalence of hepatitis E(HEV)in the Gongshu District Hangzhou,from 2011 to 2020,and to provide a basis for the development of prevention and control measures for HEV.Methods Data on reported cases of HEV in the Gongshu District of Hangzhou City from 2011 to 2020 were collected from the Chinese disease prevention and control information system.Descriptive research methods were employed to analyze the data,and the concentration value method was used to perform seasonal analysis.Results From 2011 to 2020,a total of 452 cases of HEV were reported in the Gongshu District.The average annual reported incidence rate was 13.27/100000.The average incidence rate among males(14.72/100000)was higher than that among females(11.81/100000),and the difference was statistically significant(χ^(2)=5.402,P<0.05).The occupations with the highest incidence rates were retirees,officials,and workers.The age group of 60 years and above had the highest incidence rate at 18.26/100000,and the incidence rate gradually increased with age(χ^(2)=7.71,P<0.05).In terms of temporal distribution,the incidence of HEV exhibited a wave-like trend over time,but no significant seasonal variation was observed.Conclusions The incidence of HEV in the Gongshu District exhibits a wave-like pattern with high rates.It predominantly affects middle-aged and elderly individuals.To address this issue,it is important to prioritize HEV prevention and control efforts.This includes strengthening health education,improving food safety regulations,and promoting vaccination among high-risk groups.
