摘　　要：目的分析重庆市南岸区人群土源性线虫感染的分布现状,为制定防治对策提供依据。方法按照《重庆市土源性线虫病现状调查方案》规定的方法和要求进行。根据地理位置和经济条件两特征分层抽样到乡镇、街道,再随机整群抽样到村,抽到的村为调查点;用改良藤涂片法(Kato-Kolz厚涂片法)检查粪便标本中各种虫卵,另外用透明胶纸肛拭法查蛲虫卵。用SAS8.2版统计分析软件,进行χ2检验,α=0.05。结果共调查2 066人,查出4种土源性线虫,蛔虫、蛲虫、鞭虫、钩虫的感染率分别为0.48%、1.90%、0.10%、16.36%,人群土源性线虫总感染率为17.13%,海棠溪街道土源性线虫感染率(2.37%)最低,长生桥镇土源性线虫感染率(28.80%)最高,农村的土源性线虫感染率远远高于城市的土源性线虫感染率。以农民为职业的感染率最高达26.08%,感染率以文盲文化程度者最高达25.99%。结论经过此次调查,掌握了南岸区本底病情资料,为南岸区下一步防治土源性线虫病提供了科学依据。Objective To analyze the distribution of soil-transmitted nematode infections in Nan-an District and provide scientific evidence for prevention and remedial measures.Methods A stratified sampling method was applied to select target towns and residential districts according to the geographic features and economic condition.Villages were selected by random cluster sampling.The modified Kato-Katz method of thick smear was applied to detect nematode eggs.Enterobius vermicularis eggs were collected by scrubbing sticky tapes around the anus of children.Results Four detected species of geohelminthes were identified as Ascaris lumbricoides,Pinwornl,Trichuris trichiura and Hookworm,which had the infection rate of 0.48%,1.90%,0.10% and 16.36%,respectively.The rate of parasite infestation was 17.13% on average,with the lowest infection rate in Haitangxi（2.37%）,and the highest in Changshengqiao（28.80%）.The infection rate of soil-transmitted nematode was significantly higher in rural area than that in city.The highest risk people were farmers（26.08%） and residents without education（25.99%）.Conclusion Efficient education program needs to be developed to prevent the high risk people from soil-transmitted nematode infections.
