1984年3～4月,对市区九所幼儿园的儿童在早上用棉拭法肛周采样,置盛有饱和盐水之试管内作蛲虫卵漂浮检查。总阳性率47.7%(804/1687),与1965年5所幼儿园的51.4%(148/288)相比无明显下降(P>0.05)。按卫生设备、环境条件、保教人员的文化卫生水平以及卫生制度和卫生工作质量归类统计:四所一类、两所二类和三所三类幼儿园的蛲虫感染率分别为40.7%(273/671),50.3%(279/555)和54.7%(252/461),差异非常显著(P<0.005),而同类幼儿园的阳性率间均差异不显著(P均>0.05),说明针对上述四方面
From March to April 1984, children in nine kindergartens in the urban area were sampled in the morning by cotton swabs, and the eggs in the test tubes filled with saturated saline were used for floating test. The total positive rate was 47.7% (804/1687), which was not significantly lower than 51.4% (148/288) in 5 kindergartens in 1965 (P> 0.05). According to the statistics of sanitary equipment, environmental conditions, cultural and hygienic level of health care workers, and health system and quality of health work, the prevalence of pinworms in four types of kindergartens were 40.7% (273 (P <0.05), indicating that there is no significant difference between the two groups (P> 0.05) Four aspects
