ABSTRACT
Objective:To determine the disinfection effect in child care institutions in Qingpu District of Shanghai, and provide evidence for improving the disinfection quality and preventing and controlling infectious diseases. Methods:According to the monitoring program of disinfection quality in child care institutions in Shanghai, disinfection quality was monitored for 3 years. Results:A total of 979 samples were monitored in the consecutive three years, in which 895 samples were qualified with a total qualification rate of 91.42%. The qualification rate of air samples was 100.00%, while the rate of staff hand samples was the lowest, with an average of 79.60%. During 2016-2018, the difference among the annual qualification rates was statistically significant(χ2=23.809,P<0.05), whereas it was not significant in the rates between public institutions and private ones (χ2=0.141,P>0.05). Conclusion:The quality of preventive disinfection in child care institutions in Qingpu District is generally good, but the disinfection of tableware, surface of objects and staff needs to be further improved.
