目的掌握贵州省人群肠道线虫感染现状。方法按全国人体重要寄生虫病现状调查实施细则进行。结果抽样10个县30个点,共查15958人,肠道线虫平均感染率47.52%,其中钩虫、蛔虫、鞭虫、蛲虫(12岁以下)的感染率分别为4.71%、42.41%、10.77%和1.67%。在30个监测点中,感染率超过50%的点有12个,钩虫感染率超过10%的有6个,鞭虫在4个点的感染率超过30%,蛔虫在8个点感染率超过50%,最高的点达83.15%。感染者中,女性感染率48.92%,高于男性的46.24%(P<0.005);年龄分布以10-14岁组少年儿童感染率56.30%最高;不同职业人群中,农民感染率最高为48.02%;调查人数在100人以上的不同民族中,感染率居前3位的为回族(70.70%)、彝族(60.57%)、汉族(49.75%)。钩、蛔、鞭虫的轻度感染者分别占感染人数的71.77%、62.85%、94.41%,重度感染者分别占0.98%、5.81%和0.06%。一人感染两虫者1600人(21.1%),感染3虫者67人(0.88%)。结论贵州省常见人体肠道线虫感染较普遍,某些地方处于较高水平,要达到控制肠道线虫流行,必须采取综合措施,深入持久的开展防治工作。
Objective To understand the status of intestinal nematode infection in Guizhou Province. Methods According to the implementation of the survey of the status of important parasitic diseases in the country. Results The infection rates of hookworm, roundworm, whipworm and pinworm (under 12 years) were 4.71%, 42.41% and 10.77 respectively in 30 counties and 15958 in total. The average infection rate of intestinal nematode was 47.52% % And 1.67%. Twelve of the 30 surveillance sites had infection rates in excess of 50%, six had hookworm infection rates in excess of 10%, whipworms infected more than 30% at four sites, and roundworms infected more than eight sites 50%, the highest point of 83.15%. The infection rate of female was 48.92%, higher than that of male (46.24%) (P <0.005). The age distribution of children aged 10-14 was the highest (56.30%). Among different occupational groups, the highest infection rate was 48.02% Among the ethnic groups with more than 100 persons, the top three were Hui (70.70%), Yi (60.57%) and Han (49.75%). Hooks, roundworm, whipworm mild infections accounted for 71.77%, 62.85%, 94.41% respectively of the number of infections, severe infections accounted for 0.98%, 5.81% and 0.06% respectively. 1,600 (21.1%) were infected with one insect per person and 67 (0.88%) were infected with 3 worms. Conclusion Common human intestinal nematode infections are common in Guizhou Province and some areas are at a high level. To control the prevalence of intestinal nematodes, comprehensive measures must be taken to carry out prevention and treatment work in depth.
