广东省2002～2003年人体重要寄生虫感染调查

Survey on human important parasites of Guangdong Province in 2002-2003

目的了解广东省人体重要寄生虫感染现状及防治效果。方法按照2001年全国统一制定的调查方案,于2002～2003年在全省范围内按地区分层整群随机抽样的方法进行调查。以Kato-Katz法检查肠道蠕虫卵,透明胶纸肛拭法检查12岁以下儿童蛲虫卵。结果土源性线虫和华支睾吸虫感染共抽样调查17县个(市、区)51个点(村)26 363人,寄生虫总感染率为28.59%。其中男性感染率为29.99%、女性为27.20%;年龄组感染率5～9岁组最高,为37.36%,15～19岁组最低,为19.56%;渔民感染率最高,为44.00%,待业人员最低,为8.70%。人群蛔虫、钩虫、鞭虫、蛲虫和华支睾吸虫感染率分别为7.78%、6.13%、4.58%、30.38%和10.13%,其中钩虫感染率女性高于男性,蛲虫、华支睾吸虫感染率男性高于女性(P均<0.01)。结论广东省肠道寄生虫感染率总体呈下降趋势,但华支睾吸虫、蛲虫感染率上升。

Objective To know about the crowd infection status and control effects of human important parasites in Guangdong Province. Methods According to the national survey scheme established in 2001, the survey was carried out by the lamination stochastic group sampling on basis of areas within the whole province in 2002--2003. Intestinal helminth eggs in stool were examined using the improved Kato-Katz＇s thick slide method and Enterobius verrnicularis eggs by cellophane swab method for children under 12. Results Totally 26 363 persons in 51 sites （villages） of 17 counties/cities/districts were samplingly surveyed this time for soil-borne nematodes and Clonorchis sinensis, with a total parasitic infection rate of 28.59%, an infection rate of 29.99% for male and 27.20% for female. The infection rate of group age 5-- 9 was highest, 37.36 %, and that of group age 15--19 lowest, 19.56 %. The occupation with the highest infection rate was fishermen （44.00%） and the lowest was the unemployed （8. 70%）. The crowd infection rates of ascarid, hookworm, whipworm, E. vermicularis and C. sinensis were 7.78%, 6.13 %, 4.58%, 30.38% and 10.13 %, respectively. The hookworm infection rate of female was lower than that of male, while the E. verrnicularis and C. sinensis infection rates of male were higher than those of female （P〈0.01）. Conclusion The infection rates of intestinal parasites in Guangdong Province showed a decrease trend as a whole, but the infection rates of C. sinensis and E. vermicularis were going up.
