江苏省苏南地区人体重要寄生虫感染现状调查

INVESTIGATION ON PRINCIPLE PARASITIC INFECTIONS IN THE SOUTHERN PART OF JIANGSU PROVINCE

目的 了解江苏省苏南地区农村人体寄生虫感染的现状和特点 ,以制订切实可行的防治措施。方法 按全国人体重要寄生虫病现状调查实施细则的要求和方法 ,在江苏省苏南地区中签的8个点中的 40 82人进行粪检。结果 寄生虫平均感染率为 6.71% ,男、女感染率分别为 4.77%和8.42 % ,两者差异非常显著 ( P<0 .0 1)。共查见寄生虫 5种 ,感染率分别为蛔虫 0 .44 % ( 18/ 40 82 )、钩虫 5 .46% ( 2 2 3 / 40 82 )、鞭虫 0 .78% ( 3 2 / 40 82 )、姜片虫 0 .0 2 % ( 1/ 40 82 )、蛲虫 2 .19% ( 9/ 411)。有 2种虫感染者占感染人数的 3 .3 0 %。蛔虫、鞭虫、蛲虫感染率 15岁以下年龄组最高 ,钩虫感染率最高的是 5 0岁以上年龄组 ,女性高于男性。结论 江苏省苏南地区人体寄生虫感染率较 10年前已有大幅度下降 ,感染虫种以钩虫为主 ,而且以美洲钩虫为优势虫种 ,少数未系统防治的乡、村 ,中。

Objective To understand the present status of human parasitic infections and their characteristics in rural areas of the southern part of Jiangsu Province, to provide basis of making practical control measures.Methods Four thousand and eighty-two people were examined with stool tests and those people were distributed in 8 slected spots in the southern part of Jiangsu Province,according to the methods of national investigation scheme on human principal parasites. Results The avarage infection rate of parasites was 6.71%. The male and female infection rates of parasites were 4.77% and 8.42%,respectively. There were significant differences (P< 0.01). Five kinds of parasites were found,in which the infection rate of ascaris was 0.44%(18/4082), hookworm 5.46%(223/4082),trichuris 0.78%(32/4082), fasciolopsis 0.02%(1/4082),enterobius 2.19%(9/411). The cases with 2 kinds of worms were 3.30% in total infection cases. The infection rates of ascaris, trichuris and enterobius in the 2 to 15-year-old groups were the highest. The rate of hookworm in the fifty-year-old and over groups was the highest, and it was higher in female than that in male. Conclusions The infection rates of human parasites in the southern part of Jiangsu Province decreased greatly compared with that 10 years ago. The infected worm was mainly hookworm in which N.americanus occupied a dominant position. A few towns and villages without systematic control and the middle-old women and children are the main target control areas and target people groups, respectively.
