目的分析2006—2016年淮安市戊型病毒性肝炎(戊肝)的流行特征和规律,为戊肝的防制提供依据。方法对淮安市2006—2016年戊肝病例进行描述流行病学分析。结果 2006—2016年淮安市报告戊肝1 817例,年平均发病率为3.28/10万;1—4月份为发病高峰,呈散发状态,城乡接合部发病高于主城区;淮安市戊肝发病以中老年为主,且≥60岁年龄组占病例总数的构成比有上升趋势(χ~2=11.03,P=0.004);男性发病多于女性,职业主要为农民。结论淮安市戊肝发病的流行病学特征有所变化,可能与戊肝病毒优势毒株变迁有关,应引起足够的重视。
Objective To analyze the epidemiological characteristics and pattern of hepatitis E virus in Huai’an city from 2006 to 2016 and provide the basis for the prevention and control of hepatitis E. Methods Epidemiological analysis of hepatitis E cases from 2006 to 2016 in Huaian City was performed. Results In Huai’an City from 2006 to 2016, 1 817 cases of hepatitis E were reported, with an average annual incidence of 3.28 / 100 000. The incidence peaked from January to April, with a sporadic appearance. The incidence of junctional areas in urban and rural areas was higher than that in the main urban area. The proportion of the total number of cases in the age group of ≥60 years had a rising trend (χ ~ 2 = 11.03, P = 0.004). The incidence of male was higher than that of female and the occupation was mainly of farmer. Conclusions The epidemiological characteristics of hepatitis E in Huaian City have some changes, which may be related to the change of the dominant strains of hepatitis E virus, which should be given enough attention.
