摘要
为进一步掌握青海省人体蛔虫感染现状,有效防治蛔虫感染。于2015年5-9月采用整群分层抽样法抽取青海省17个县(市)53个调查点采集常住居民(1岁以上)粪样。采用改良加藤厚涂片法(Kato-Katz法)(一粪三检)粪检蛔虫感染情况,应用SPSS 22.0软件分析调查结果。结果显示,共调查13 660人,蛔虫感染者140例,感染率为1.05%,其中轻度感染133例(占95.00%),中度感染4例(占5.00%),未见重度感染者。人群感染率以平安县(2.49%)和民和县(2.13%)较高,且不同地区间差异有统计学意义(χ~2=70.924,P<0.05);0~10岁组感染率(2.58%)高于其他年龄组(P<0.05);粪检蛔虫卵阳性者中,汉族感染率(1.95%)高于其他民族(P<0.05);学龄前儿童感染率(2.24%)高于其他职业人群(P<0.05)。未受精蛔虫卵占99.29%(139/140),仅共和县检出1例受精蛔虫卵。提示该省蛔虫感染率和感染度均较低。
The aim of this study was to further understand the status of Ascaris infection in humans and facilitate effective control of ascariasis in Qinghai Province. The cluster-stratified sampling method was used to detect worm eggs in 53 investigation points in 17 counties （cities） from May to September, 2015. The intestinal helminth eggs in fecal samples from residents were detected by the Kato-Katz thick smear method （one sample for three tests）, and results were analyzed by SPSS 22.0 software. A total of 13 660 persons were examined, and 140 were infected with roundworms （infection rate 1.05%）, comprising of 133 （95.00%） light infections and 4 （5.00%） moderate infections. No heavy infection was found. The prevalence of Ascaris was higher in Ping＇an （2.49%） and Minhe （2.13%） than in other counties （~ = 70.924, P 〈 0.05）. The population of 0-10 years showed higher infection rate than other age groups （P 〈 0.05）. The Han population showed higher infection rate than other ethnicities （P〈 0.05）. The preschool children had higher infection rate than other occupation groups （P〈 0.05）. Unfertilized Ascaris eggs accounted for 99.29% （139/140）, and only one case was found with fertilized eggs in Gonghe county. The results indicate that both prevalence and intensity of Ascaris infection are low in Qinghai.
