摘　　要：目的分析2005―2020年浙江省戊型病毒性肝炎(hepatitis E,HE)流行病学特征及变化趋势,为防控策略的制定提供依据。方法从中国疾病预防控制中心信息系统获取2005―2020年浙江省HE监测数据,采用描述性流行病学方法分析HE时空分布特征。结果2005―2019年浙江省HE报告病例和报告发病率窄幅波动。男性报告病例率高于女性,但男性报告病例率总体呈下降趋势。“高-高”聚集区主要位于杭州市和衢州市等地区,存在明显的时空聚集性。结论2005―2020年浙江省HE疫情整体呈平稳趋势,不同性别、年龄组的发病趋势不同。Objective This study endeavors to delineate the epidemiological characteristics and changing patterns of hepatitis E(HE)infection in Zhejiang Province from 2005 to 2020.The findings aim to provide evidence for the development of measures to prevent and manage the HE epidemic.Methods Data on the incidence of HE in Zhejiang Province were extracted from the Chinese notifiable infectious disease reporting system.The temporal and spatial distribution characteristics were examined using descriptive epidemiological methods.Results From 2005 to 2019,the reported cases and incidence rate of HE in Zhejiang Province fluctuated narrowly without a notable rising trend.Although the incidence rate of HE is still higher in males than in females,the overall trend is down for males.Spatial autocorrelation analysis indicated that there was significant spatial-temporal clustering of HE in Zhejiang Province,and"High-high"clustering areas were mainly located in cities such as Hangzhou and Quzhou.Conclusions The epidemic situation of HE showed a stable trend in Zhejiang Province,but the trend was varied by gender and age groups.
