江苏省人体重要寄生虫病流行现状调查与分析

目的了解江苏省人体重要寄生虫病流行现状,评估防治效果。方法按照《全国人体重要寄生虫病现状调查实施细则》规定的方法和要求进行。结果共查出9种寄生虫,人群土源性线虫感染率7.68%,华支睾吸虫病流行区人群感染率为0.74%,12岁以下儿童蛲虫感染率11.75%,囊尾蚴病血清学阳性率为0,人群弓形体血清学阳性率为7.19%。在162所县级以上医院调查,10年共有3 746例寄生虫病住院病例,其中85%是由蛔虫寄生引起。苏南地区主要以钩虫感染为主,苏中地区钩虫、蛲虫感染率较高,苏北地区蛔虫、蛲虫感染率较高。低年龄组和中老年农民是感染寄生虫的高危人群,苏北地区感染率明显高于其他地区。结论与1990年寄生虫分布调查相比,土源性线虫总感染率和各虫种感染率均大幅度下降,但土源性线虫病仍是江苏省目前流行的主要寄生虫病。
