Results and analysis of terminal disinfection effect evaluation of COVID-19 epidemic sites
Objective To explore the method of terminal disinfection and effect evaluation by evaluating the terminal disinfection effect of COVID-19 epidemic sites.Methods According to WS/T 774-2021,the disinfection effects of air and object surfaces in 281 epidemic sites of Xuzhou city were evaluated,and the disinfection effects of different places,different disinfection personnel and different time periods were compared.Results 290 points were selected as air and object surface points respectively,and 284 air points and 252 object surface points were qualified,with a overall qualified rate of 92.41%.The qualified rate of 97.93%in air points and 86.90%in object surface points were achived.There is no difference in disinfection effect between family and public places,as well as no difference between different disinfection personnel;the qualified rate of early disinfection was relatively low,and the difference was statistically significant compared to later disinfection(P<0.05).Conclusion The overall qualified rate of the terminal disinfection effect evaluation in this round of epidemic is relatively low,and the technical level of professional personnel is insufficient.In the next step,training efforts will be intensified to improve the technical capacity of disinfection in the city,so as to ensure the standardized,scientific and accurate implementation of disinfection work.
