新冠肺炎隔离病区手触式消毒剂按钮新型冠状病毒污染调查

2019-nCoV contamination on hand-touched buttons of alcohol-based hand rub in COVID-19 isolation ward area

目的了解某区域性新型冠状病毒肺炎定点救治医院隔离病区手触式速干手消毒剂(以下简称手消)按钮新型冠状病毒污染状况,为指导隔离病区消毒提供循证依据。方法对该隔离区内5个区域(确诊病房、病区内走廊、第一缓冲间、第二缓冲间、清洁区)手触式手消按钮进行采样,采用逆转录聚合酶链反应(RT-PCR)检测标本中新型冠状病毒污染情况。结果共采集76份手消按钮标本,隔离区新型冠状病毒污染率为10.53%,其中确诊病房内污染率14.29%,病区内走廊污染率12.50%;第一缓冲、第二缓冲区、清洁区污染率均为0。结论该隔离病区病房内手消按钮新型冠状病毒污染严重,需要加强清洁消毒,并建议隔离病区使用手背按压,有条件的医疗机构宜使用感应式手消出液器或洗手感应监测仪。

Objective To understand 2019-nCoV contamination on hand-touched buttons of alcohol-based hand rub in the isolation ward area of a regional coronavirus disease 2019(COVID-19)treatment hospital,and provide evidence for guiding disinfection in isolation ward area.Methods Hand-touched buttons of alcohol-based hand rub in 5 regions of the isolation ward area(confirmed ward,ward corridor,first buffer room,second buffer room,clean zone)were sampled,and contamination in specimens were detected with reverse transcription polymerase chain reaction(RT-PCR).Results A total of 76 button specimens were collected,2019-nCoV contamination rate in isolation ward area was 10.53%,contamination rates of buttons in confirmed ward and ward corridor were 14.29%and 12.50%respectively,contamination rates in the first buffer zone,the second buffer zone,and clean zone were all 0%.Conclusion Hand-touched buttons of alcohol-based hand rub in this isolation ward area are seriously contaminated by 2019-nCoV,cleaning and disinfection needs to be strengthened,it is suggested that buttons in isolation ward area should be pressed by the back of the hand,if medical institution is conditional,inductive liquid outlet and hand-washing sensor monitor should be used.
