湖北省人体旋毛虫病血清流行病学调查分析

Investigation of serum epidemiology of trichinella spiralis in Hubei

目的了解旋毛虫病在湖北省的流行程度和分布规律。方法按照《全国人体重要寄生虫病现状调查实施细则》进行调查，采用酶联免疫吸附试验（ELISA）法进行检测。结果调查了全省10个县（市、区）19个点的9939人份血清，血清阳性人数251人，阳性率为2．53％，鄂西北的襄阳区、郧县血清阳性率较高，分别为6．09％和5．57％。人群感染率以50～59岁年龄组最高（3．82％）。男、女阳性率分别为2．98％和2．01％。结论旋毛虫感染在湖北地区呈散在分布，其中以鄂西北的襄阳区、郧县较高。应采取有效的综合防制措施，减少感染。

Methods Serum investigation of trichinella spiralis was carried out with ELISA according to the 《State scheme of parasites investigation》. Results 9 939 people in 10 counties were tested, the average serum positive rate of trichinella spiralis was 2.53%. The results showed that the epidemic of trichinella spiralis was scattered and the serum positive rate in the northwest of Hubei was the highest （5.57%-6.09%）, while the highest positive rate（3.82 %） was in the age group of 50-59 years old. Conclusion The epidemic of trichinella spiralis was scattered, the serum positive rate in the northwest of Hubei was the highest, and the highest positive rate was in the older age group. Comprehensive measures should be carried out for the control of trichinella spiralis.
