Soil-transmitted Helminth Infection in Outpatients of People' s Hospital of Yunxian County in Yunnan Province

目的了解2014年在云南省云县人民医院门诊患者中开展土源性线虫监测情况。方法采用改良加藤厚涂片法镜检虫卵。结果在统计分析的1002位门诊病人中，土源性线虫总感染率6．79％[95％可信区间（CI）：5．34％-8．57％]，其中蛔虫、钩虫和鞭虫感染率分别为1．70％（95％CI：1．02～2．76）、4．69％（95％凹：3．50～6．24）和0．80％（95％CI：0．37—1．83）。学龄前（〈7岁）儿童感染率最高，15．63％（95％CI：9．81～23．09）；与326岁年龄组比较，多因素Logistic回归分析调整后比值比（OR）为2．97（1．68-5．79）。感染无季节性差异（X^2=3．17，P=6743）。结论云南省云县人民医院门诊土源性线虫感染率学龄前儿童较高。

Objective To investigate soil - transmitted helminth infection in outpatients of People＇s Hospital of Yunxian County in Yunnan Provinee in 2014. Methods Using the modified Kato Katz thick smear microsco- py, stool samples were examined for helminth eggs. Results The total helminth infection rate was 6. 79% [95% confidence interval （CI） ： 5.34 - 8.57% ） ] among 1002 statistically analyzed outpatients. The infec- tion rates of Ascaris lumbfieoides, hookworm and Trichuris trichiura were 1.70% （95 % CI： 1.02 -2. 76）, 4. 69% （95% CI： 3.50 -6.24） and 0. 80% （95% CI： 0. 37 - 1.83）, respectively. The highest infection rate was found in preschool children （ 〈7 years） , being 15.63% （95% CI： 9.81 -23.09）. Compared to the age group of ≥ 26 years, the odds ratio （OR） following adjustment by multivariate Logistic regression analysis was 2. 97 （95%（7/： 1.68 -5.79） . No seasonal difference was found in infection （X^2 =3. 17, P = 6743 ）. Conclusion The soil -transmitted helminth infection rate is high in preschool children in outpatients of Peopleg Hospital of Yunxian County in Yunnan Province.
