摘　　要：目的监测新型冠状病毒感染(COVID-19)疫情以来北京市重点公共场所卫生状况,分析疫情对公共场所室内空气质量和物体表面卫生的影响,为COVID-19疫情防控常态化背景下公共场所卫生管理提供数据支持。方法现场采样并检测2018—2021年宾馆酒店、候车场所室内空气CO 2、PM 2.5、PM 10、空气细菌总数及物体表面细菌总数;同时调查场所通风情况、从业人员疾病传播风险知晓情况,并对结果进行汇总分析。结果COVID-19疫情对北京市宾馆酒店、候车场所的通风方式无明显影响(P>0.05),疫情发生后公共场所从业人员的疾病传播风险知识知晓率为高于疫情发生前,差异具有统计学意义(P<0.05)。COVID-19疫情发生后宾馆酒店、候车场所总体卫生指标合格率为98.4%,检测合格率优于疫情发生前(P<0.05);且疫情发生后宾馆酒店CO 2、PM 2.5、PM 10及候车场所CO 2、物体表面细菌总数低于疫情发生前,差异有统计学意义(P<0.05)。结论COVID-19疫情发生后,通过加强通风换气、控制室内人数等各项疫情防控措施的实施,以及防疫知识的宣传教育,使北京市重点公共场所卫生状况较疫情发生前有了更进一步的提高。Objective To monitor the sanitary conditions of some key public places in Beijing,China since the COVID-19 outbreak,analyze the impact of COVID-19 on indoor air quality and bacterial colonies on object surfaces in public places,and provide data for hygienic management in public places in the context of normalized epidemic prevention and control.Methods Samples were collected from 2018 to 2021 in hotels and station waiting rooms for detection of CO 2,PM 2.5,and PM 10,as well as total number of bacterial colonies in indoor air and on object surfaces.Meanwhile,the ventilation of the site and the knowledge of the disease transmission risk of the practitioners were investigated,and the result were summarized and analyzed.Results There was no significant impact of COVID-19 on the ventilation mode of hotels and station waiting rooms in Beijing(P>0.05),and the awareness rate of disease transmission risk knowledge among employees in public places was significantly higher after the outbreak than that before the outbreak.The difference was statistically significant(P<0.05).The overall qualified rate of hygienic indicators in hotels and station waiting rooms was 98.4%after COVID-19 outbreak,which was significantly higher than that before the epidemic(P<0.05).Moreover,the concentrations of CO 2,PM 2.5,PM 10 in indoor air of hotels,and the concentrations of CO 2 in indoor air and total number of bacterial coloniest on object surfaces in station waiting rooms were significantly lower after the epidemic(P<0.05).Conclusion After the outbreak of COVID-19,epidemic prevention and control measures,such as strengthening ventilation and controlling the number of people indoors,together with publicity and education of epidemic prevention knowledge,have improved the sanitary situation in key public places in Beijing.
