2003-2005年宁波市流动人口血吸虫病管理与监测

目的 检测外来流动人口携带血吸虫病的情况,评价其对宁波市人群传播血吸虫病的潜在危害,从而预防和控制外源性血吸虫病在该市传播.方法 对来自安徽、湖南、湖北、江苏、江西、四川、云南等7个省血吸虫病疫区的部分外来人员,进行血吸虫病间接血凝法(IFA)和金标免疫渗滤法(DIGFA)检测,阳性者用尼龙绢集卵孵化法(粪孵法)进行病原学检查,同时开展健康教育及患者现住地村庄周围查螺.结果 2003-2005年共检测外来流动人口14 529人,阳性178例,血清阳性率为1.23%,45例阳性者粪孵找到血吸虫病原体,粪孵阳性率25.28%;普查钉螺32个村,合计查螺面积31104m2,没有查到钉螺.结论 外来流动人口携带血吸虫病原体情况存在,必须加强外来流动人口血吸虫病管理与监测,以有效预防和控制外源性血吸虫病在宁波市传播.

Management and surveillance of the floating population with schistosomiasis in Ningbo City from 2003 to 2005

And at the same time health education was carried on and snails were screened around the villages where the patients lived. Results From 2003 to 2005, 14 529 floating people were examined and there were 178 positive people. The serum positive rate was 1.23%. Pathogeny of schistosomiasis was found in 45 positive people, and the positive rate of fecal hatching test was 25.28%. Snails were screened in 32 villages. The areas where snails were checked added up to 310 000 m2, but no snails were found.
