Abstract:
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.
