摘　　要：目的分析四川省肠道蠕虫病流行现状和态势,评估十余年来的防治效果,为制定肠道蠕虫病防治措施提供科学依据。方法采用Kato-Katz法检查肠道蠕虫卵;试管滤纸培养法鉴别钩虫虫种及其他线虫;透明胶纸肛拭法查12岁以下儿童蛲虫卵。结果共查见肠道蠕虫9种,即线虫5种、吸虫2种、绦虫2种。肠道蠕虫感染的标化感染率为39.79%,其中钩虫、蛔虫、鞭虫标化感染率分别为19.77%、23.12%、6.82%。以此推算,目前全省肠道蠕虫的感染人数约有3 314万,其中钩虫感染者1 647万、蛔虫感染者1 926万、鞭虫感染者568万。与全国第一次人体寄生虫分布调查结果相比,钩、蛔、鞭虫感染率分别下降了48.40%、61.34%和76.14%,12岁以下儿童的蛲虫感染率上升了26.54%,带绦虫感染率差异无统计学意义。结论目前我省钩、蛔、鞭虫等土源性线虫感染率有了一定程度的下降,但是由于感染基数高,人们的生产、生活及卫生习惯未发生根本性的改变,因而要在全省范围内达到基本控制肠道蠕虫感染目标尚有较大差距。Objective To analyse the intestinal helminthiasis epidemic situation and to evaluate the control effect in past ten years so as to make out the control strategy in Siehuan Province. Method A total of 26 292 persons in 52 random cluster sampling spots of 18 counties were selected according to the detailed rules and regulations of nation-wide investigation on key parasitoses issued by the Ministry of Health of China. The methods of Kato-Katz, test tube filter incubation, and cellophane anal test were used. Result 9 species of intestinal helminth including 5 of nematode,2 of trematode,2 of tenia were found. The standardized infection rates and estimated number of human infections were as follows： Intestinal helminth 39.79% and 33.14 million persons,hookworm 19.77% and 16.47 million persons, roundworm 23.12% and 19. 26 million persons, and whipworm 6. 82% and 5.68 million persons. As compared with that of first nation-wide investigation on human parasitoses,the infection rates of hookworm, roundworm and whipworm were dropped by 48.40% ,61.34% and 76.14% respectively,but there were no significant difference in infection rate of tenia,and the pinworm infection rate in children under 12 years old inreased by 26.54%. Conclusion Though the infection rates of some parasitoses have been dropped in certain degree,it would be an arduous task to control the human intestinal helminthiasis in whole Siehuan Province because of the higher infection base and unhealthy habits in production,living and sanitation.
