摘　　要：[目的]调查浙北地区自然人群戊型肝炎流行特征,城镇、农村山区、农村平原三种不同类型居住地区对戊型肝炎流行率的影响。[方法]2006年,在浙江省湖州市以多阶段整群系统随机抽样方法采集1～59岁自然人群1686份血清,采用ELASA方法测定血清抗-HEVIgG,同时调查分析有关影响因素。[结果]在调查的1666人中戊肝平均流行率为44.96%,标化后为38.88%,男女流行率差异无统计学意义。戊肝流行率随着年龄的增长而升高,流行率与年龄呈正相关(r=0.991)。城镇、平原戊肝流行率明显高于山区。[结论]浙北地区属戊肝高流行区。戊肝流行率与年龄和居住地区类型显著相关,而性别、职业、文化程度对戊肝流行率影响不明显。To explore the epidemiological characteristics of hepatitis E in different areas such as towns、mountainous areas and plain water villages in the north of Zhejiang province.[Methods]1 666 people aged from 1 to 59 as the study population were selected from the total population in Huzhou city by the method of multi-stage cluster randomized sampling.The study was based on epidemiological investigation of cases study and blood collection,while the HEV-IgG antibody of hepatitis E was tested by using ELISA.[Results]The total infectious rate of HEV was 44.96%,while the standardized infectious rate was 38.88%. There was no significant difference in the infectious rates between males and females,and it was positively correlated with age（r=0.991）.The infectious rates of HEV in towns and plain water villages were obviously higher than that in mountainous areas.[Conclusion]The north of Zhejiang province is hyperendemic areas of HEV. Age and living area have significant influence on the prevalence of HEV,while sex,profession and education level are not so influencing.
