| 摘要 目的：了解新型冠状病毒（以下简称"新冠"）肺炎定点医院病区终末消毒控制措施并监测其消毒效果。方法：对中山大学附属第五医院隔离病区实施终末消毒，并对终末消毒前后空气和物表进行采样检测及终末消毒后环境进行采样检测，评估消毒效果。结果：对14个隔离病区开展了终末消毒，终末消毒前后均采集空气沉降菌样品156份、物表样品254份，终末消毒后采集环境核酸样品209份进行消毒效果评价。各隔离病区经终末消毒后空气消毒效果合格率均为100.00%，高于终末消毒前空气消毒效果合格率76.20%（P<0.05）；终末消毒后物表消毒效果为94.88%，高于终末消毒前物表消毒效果合格率71.65%（P<0.05）；终末消毒后环境核酸检测结果均为阴性。结论：中山大学附属第五医院各隔离病区经终末消毒后各项指标均符合终末消毒评价要求。 |

| ABSTRACT Objective: To understand the terminal disinfection control measures of COVID-19 (designated "new crown") hospital and to monitor its disinfection effect. Methods: The terminal disinfection was carried out in the isolated ward of the Fifth Affiliated Hospital of Sun Yat sen University, and the air and object surface before and after terminal disinfection were sampled and tested, and the environment after terminal disinfection was sampled and tested to evaluate the disinfection effect. Results: Terminal disinfection was carried out in 14 isolated wards. 156 air sedimentation bacteria samples, 254 surface samples were collected before and after terminal disinfection, and 209 environmental nucleic acid samples were collected after terminal disinfection for disinfection effect evaluation. The qualified rate of air disinfection effect in each isolated ward after terminal disinfection was 100.00%, which was higher than 76.20% before terminal disinfection (P<0.05). The efficacy of surface disinfection after terminal disinfection was 94.88%, which was higher than that before terminal disinfection, and the qualified rate was 71.65% (P<0.05). The results of environmental nucleic acid test after terminal disinfection were negative. Conclusion: After terminal disinfection, all indexes of isolated wards in the Fifth Affiliated Hospital of Sun Yat sen University met the requirements of terminal disinfection evaluation. |
