目的了解牡丹江市戊型肝炎流行情况,为制定戊型肝炎控制措施提供依据。方法在全市范围内随机选取健康人群626人,特殊职业(专业养猪人员)人群298人,共计924人进行了戊型肝炎血清流行病学调查。结果牡丹江市戊型肝炎感染率为15.02%,特殊职业人群感染率为42.28%。戊型肝炎感染率1~15岁和30~59岁年龄段递增趋势不明显,15~29岁感染率随年龄增长明显升高。性别差异无统计学意义。各县(市)区及城乡无明显差异。结论特殊人群感染率是一般人群的2.81倍,差异有统计学意义(P<0.01),可能与猪戊型肝炎有关。
Objective To understand the prevalence of hepatitis E in Mudanjiang and provide evidence for the development of hepatitis E control measures. Methods A total of 626 healthy people and 298 special occupation pigs (professional swine workers) were randomly selected in the whole city. A total of 924 people were enrolled in the hepatitis E epidemic survey. Results The prevalence of hepatitis E infection in Mudanjiang City was 15.02%, and the infection rate in special occupational groups was 42.28%. Hepatitis E infection rate of 1 to 15 years and 30 to 59 years of age increasing trend is not obvious, 15 to 29 years old infection rate increased significantly with age. Gender differences were not statistically significant. There is no significant difference between counties (cities) and urban and rural areas. Conclusions The infection rate of special population is 2.81 times that of the general population, the difference is statistically significant (P <0.01), which may be related to swine HE.
