江苏省人体重要寄生虫病流行现状调查

目的了解江苏省人体重要寄生虫病流行现状与态势,评估防治效果,为制定防治计划提供依据。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10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华支睾吸虫感染率为0.74%,12岁以下儿童蛲虫感染率为11.75%,囊虫病血清学阳性率为0,特殊人群弓形虫血清学阳性率为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。结论与第一次寄生虫分布调查相比,虽然总感染率和各虫种感染率均大幅度下降,但土源性线虫病目前仍是江苏省流行的主要寄生虫病。

INVESTIGATION ON THE EPIDEMIC SITUATION OF PRINCIPAL HUMAN PARASITIC DISEASES IN JIANGSU PROVINCE

Objective To understand and analyze the epidemic situation of parasitosis,evaluate the control effects and provide basis for making practical control measures. Methods To carry out according to the methods of National Investigation Scheme on Human Principal Parasites.Results Ten kinds of parasites were found in the survey.The total infection rate of soil-helminth in population was 7.68%.The infection rate of C.sinensis in its endemic areas was 0.74%,E.vermicularis in children under twelve years old was 11.74%,cysticercus in serology was 0 and toxoplasma in serology among special people was 7.19%.3 746 hospitalized cases caused by parasites were found in 162 county-and over-hospitals in 10 years,in which 85% were brought with ascaris.Hookworm was prevailing in the southern of Jiangsu Province,hookworm and E.vermicularis were prevalent in the median of Jiangsu Province and ascaris and E.vermicularis were prevalent in the northern part of Jiangsu Province.These people in the low-aged and the mid-and older-aged peasants were in high risk.The infection rate in the northern part of Jiangsu Province was obviously higher than that in the southern part of Jiangsu Province.Conclusion The total infection rate of parasites had greatly decreased,but soil-helminthsis were still endemic principal parasitic diseases in Jiangsu Province now.
