By stratified cluster sampling method, 2 urban and 2 rural fields were selected from Shapingha district of Chongqing for survey in December 2009 to February 2010. According to the Administrating Regulations of National Investigation on Important Human Parasitic Diseases, Kato-Katz method was used to examine human intestinal soil-borne nematode eggs, and adhesive cellophane anal swab method was applied to examine Enterobius infection for children under 12 years old. 203 cases were found positive in 2121 subjects, with an infection rate of 9.6% (203/2 121), and the infection rate of hookworms, Ascaris lumbricoides and Trichuris trichiura with mild infection mostly was 9.3% (197/2 121), 0.4% (8/2 121) and 0.1% (2/2 121), respectively. The rate among people over 50 years old was 15.5% (160/1 030), and the farmers was with 22.3%(113/506). The higher the education level, the lower the infection rate (P < 0.01), and there was a significant difference in the prevalence between urban (2.1%) and rural people (17.3%) (chi2 = 140.443 5, P < 0.01). The infection rate of soil-borne nematodes in Shapingba of Chongqing was much lower than the standard of II regions and most infected subjects were with hookworm infection.
2009年12月至2010年2月，采用分层整群抽样方法，从重庆市沙坪坝区选取2个城市社区和2个农村地区进行调查。按照《全国重要人体寄生虫病现状调查实施方案》，采用改良加藤厚涂片法检查人体肠道土源性线虫卵，用透明胶纸肛拭法检查12岁以下儿童蛲虫感染情况。2121名调查对象中，203人检查出阳性，感染率为9.6%（203/2 121），其中钩虫、蛔虫和鞭虫感染率分别为9.3%（197/2 121）、0.4%（8/2 121）和0.1%（2/2 121），且大多为轻度感染。50岁以上人群感染率为15.5%（160/1 030），农民感染率为22.3%（113/506）。文化程度越高，感染率越低（P<0.01），城乡感染率差异有统计学意义，城市为2.1%，农村为17.3%（χ2 = 140.443 5，P<0.01）。重庆市沙坪坝区土源性线虫感染率远低于二类地区标准，且感染以钩虫为主。
