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（χ2 = 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。提示该地区蛔虫感染率和感染度均较低。
In order to further grasp the status of human roundworm infection in Qinghai Province, effective prevention and treatment of roundworm infection. From May to September 2015, stratified sampling method was used to collect fecal samples from 53 survey sites of 17 counties (cities) in Qinghai Province for permanent residents (over 1 year old).

The infection rate of the population was higher in Ping County (2.49%) and Minhe County (2.13%), and the difference was statistically significant among different regions (χ2 = 70.924, P <0.05) ) Was higher than other age groups (P <0.05). Han Chinese infection rate was 1.95% higher than that of other ethnic groups (P <0.05). Prevalence rate of preschool children was 2.24% Other occupational groups (P & lt; 0.05). Unfertilized Ascaris eggs accounted for 99.29% (139/140), only a check of Gonghe County ascaris eggs. Tip roundworm infection rate and the degree of infection in the area are low.
