摘要
目的 了解湖北省人体土源性线虫感染现状及流行特点,为制定防治策略提供科学依据。方法 按照全国统一方案,采用分层整群抽样法抽取湖北省10个县(市)30个调查点,每点调查约500人。用改良加滕厚涂片法检查土源性线虫卵;试管滤纸培养法鉴定钩虫虫种;透明胶纸肛拭法查12岁以下儿童蛲虫卵。结果共调查15524人,土源性线虫感染4761人,总感染率30.67%。其中蛔虫、鞭虫、钩虫和蛲虫感染率分别为26.86%、7.38%、2.89%和2.67%。不同县(市)感染率差异显著,三类地区为41.60%,二类地区为33.33%,一类地区为19.03%;女性感染率(31.75%)高于男性(29.67%);总感染率和鞭虫感染率5~9岁组最高,钩虫感染率45~69岁组最高,蛔虫感染率50~54岁组最高。结论湖北省人体土源性线虫感染普遍,感染率〉20%和未开展系统防治的县(市)、低年龄组儿童和中老年妇女是土源性线虫病防治的重点地区和重点人群。
Objective To understand infection status and epidemic characteristics of geohelminthes in Hubei Province. Methods According to national unified plan, with stratified cluster sampling method, 30 spots in 10 counties (cities) were investigated and 500 persons were selected in each spot. Geohelminthes ova was examined by Kato-Katz thick smear method; Hookworm species were identified by tube filter paper culture method; Oxyurid ova were examined for children younger than 12 by cellophane anal swab. Results Total 15 524 persons were investigated. 4 761 persons were infected with geohelminthes, the infection rate was 30. 67%. The infection rate of roundworm, whipworm, hookworm and oxyurid was 26. 86%, 7. 38%, 2.89% and 2.67% respectively. There was a significant difference of infection rate be tween counties, with the third class areas (41.60%) higher than the second class areas (33.33%) and the second class higher than the first class areas (19.03%); the infection rate for female (31. 75%) was higher than male(29.67%); the general infection rate and whipworm infection rate was the highest in 5-9 age group, the highest infection rate of hookworm and roundworm was in 45-69 age group and 50-54 age group respectively. Conclusion The counties (cities) with infection rate above 20% and no systematic control measures are the key areas, and children in the low age group and middle-aged and senior women are the key target people of geohelminthiasis control in the future.
