          Objective To comprehensively understand the disinfection quality of secondary and primary schools and kindergartens in Wuxi, so as to find out problems and to provide advice for improvement.

          Methods Stratified random sampling method was applied in the investigation to select 73 schools and classes. The qualities of room air, surface of object, hand hygiene of staff, tableware, ultraviolet lamp and disinfectant in use (including bacterial contamination and concentration of chlorine-containing) were all tested.

          Results A total of 2 563 samples were collected with the total disinfection qualified rate 88.02%. The qualified rates of kindergarten, primary and secondary schools were 87.89%, 90.67% and 85.83% respectively. The rates of Xishan and Jiangyin districts were 75.24% and 75.89% respectively. The quality of urban schools was better than the rural (χ 2 = 16.57, P<0.01). There was no statistical significance between public and private schools (χ 2 = 0.01, P = 0.92). The rank of qualified rates of different objects was: bacterial contamination (100.00%) > room air (93.13%) > tableware (91.87%) > surface of object (89.40%) > ultraviolet lamp (84.00%) > concentration of chlorine-containing (73.68%) > hand hygiene of staff (73.53%). The quality of secondary schools was lower than kindergartens and primary schools in the aspects of room air and surface of object.

          Conclusion The disinfection quality of secondary and primary schools and kindergartens in Wuxi is good in general. More attention should be paid on hand hygiene, concentration of chlorine-containing and ultraviolet lamp. The qualities of room air and surface of object of secondary schools need to be improved.


          【摘要】 目的 了解无锡市中学、小学和幼儿园的消毒质量现状, 为査找存在的问题并提出改进建议提供参考。 方法 采用分层随机抽样的方法选取无锡市 73 所学校, 对室内空气、物体表面、工作人员手、餐饮具、紫外线灯以及使用中消毒剂 (染菌量和含氯消毒剂有效氯浓度) 进行检测。 结果 共采集标本 2 563 份, 合格率为 88.02%, 幼儿园、小学和中学的合格 率分别为 87.89%, 90.67%, 85.83%。锡山区和江阴市学校的合格率较低, 分别为 75.24%, 75.89%。城区学校的合格率 (89.51%) 髙于农村 (83.44%) (χ 2 = 16.57, P<0.01), 公办 (87.99%) 和民办学校 (88.17%) 的合格率差异无统计学意义 (χ 2 = 0.01, P = 0.92)。不同对象的合格率依次为使用中消毒剂的染菌量 (100.00%)、空气 (93.13%)、餐饮具 (91.87%)、物体表面 (89.40%)、紫外线灯 (84.00%)、含氯消毒剂有效氯浓度 (73.68%)、工作人员手 (73.53%)。中学空气和物体表面的合格率 均低于幼儿园和小学 ( P 值均<0.05)。 结论 无锡市中小学校和幼儿园的消毒质量情况总体较好。要重点关注工作人员 手、含氯消毒剂有效氯浓度以及紫外线灯, 加强中学环境中空气和物体表面的消毒质量。
