新型冠状病毒感染疫点终末消毒效果评价结果与分析

Results and analysis of terminal disinfection effect evaluation of COVID-19 epidemic sites

目的通过对新型冠状病毒感染疫点终末消毒进行效果评价,探讨终末消毒和效果评价方法。方法按照WS/T 774—2021对徐州市281个疫点行终末消毒时的空气和物体表面消毒效果进行评价,比较不同场所、不同消毒实施人员和不同时间段消毒效果。结果抽取空气和物体表面各290个点位,空气消毒合格284个,物体表面252个,总合格率92.41%,空气合格率97.93%,物体表面合格率86.90%;家庭和公共场所、不同现场消毒人员消毒效果无差异;消毒前期合格率较低,与后期比较差异有统计学意义(P<0.05)。结论本轮疫情终末消毒效果评价总体合格率较低,专业人员技术水平有欠缺,下一步将加大培训力度,提高全市消毒技术能力,保证消毒工作规范科学精准开展。

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.
