目的了解山西省土源性线虫感染现状,为制定该省寄生虫病防治策略和措施提供科学依据.方法根据地理位置随机抽取各市近北端的12个县(区)为监测点,于2011年10-12月,采用改良加藤厚涂片法对监测点3周岁以上居民进行粪便土源性线虫(蛔虫、鞭虫、钩虫、蛲虫等)虫卵检测.计算感染率及感染度.结果 12个省级监测点共调查11 819人,查出蛔虫、鞭虫、蛲虫等土源性线虫感染者119例,总感染率为1.01％.其中蛔虫感染者39例,感染率为0.33％；鞭虫感染者1例,感染率为0.01％；蛲虫感染者79例,感染率为0.67％.39例蛔虫感染者分布于阳高县、偏关县和万荣县等3个县,1例鞭虫感染者分布于阳高县,79例蛲虫感染者集中分布于万荣县.万荣县蛲虫感染率为7.84％,各年龄组间感染率差异有统计学意义(x2=71.46,P＜0.05),且有64.56％(51/79)的感染者存在家庭聚集性.结论 2011年土源性线虫总感染率及蛔虫、鞭虫、蛲虫感染率与第二次全国人体重要寄生虫病现状调查时山西省情况比较均呈下降趋势.万荣县蛲虫感染率远高于第二次全国寄生虫病现状调查时全省蛲虫感染平均水平,12岁以下人群感染率也高于当时全省同年龄人群平均水平；蛲虫感染具有很高的家庭聚集性.

Objective To understand the status of soil-transmitted nematode infections in Shanxi Province and provide scientific basis for prevention and control strategy and measures.Methods 12 surveillance sites located north of the city were randomly selected.Fecal samples of the inhabitants of 3 years old and above were collected and examined for intestinal nematodes eggs by modified Kato-Katz's thick smear technique.Infection rate and infection intensity were calculated.Results A total of 11 819 people were surveyed at 12 provincial surveillance sites and 119 people were infected with soil-transmitted nematodes including Ascaris,Trichuris and pinworm,the total infection rate was 1.01％.Among them,39 were infected with Arcaris,1 with Trichuris and 79 with pinworm,the prevalence of which were 0.33％,0.01％ and 0.67％ respectively.All of the people infected with pinworm were from Wanrong County in Yuncheng City.The prevalence of pinworm at Wanrong County site was 7.84％,the difference of which among different age groups was significant statistically(x2 =71.46,P＜0.05),and family clustering was found in 64.56％ (51/79) patients.Conclusion Total prevalence of soil-transmitted nematodes and Ascaris,Trichuris and pinworm in 2011 declined compared with the infection condition of the second survey on the status of important human parasitic diseases in Shanxi Province.The pinworm prevalence at Wanrong County site was far higher above average prevalence of the Second Survey in Shanxi Province.The results also showed that pinworm infection is a disease with the feature of high family clustering.
