摘　　要：目的根据对一起新型冠状病毒肺炎单位聚集性疫情过程的梳理,探讨新型冠状病毒肺炎人群中传播的规律特征,对单位集体宿舍的居住环境要求给予指导建议,为院外急救时新型冠状病毒肺炎的识别提供参考,提高防护意识,降低感染率。方法对北京急救中心2020年2月27日—29日期间转运的一起单位聚集性确诊病例进行回顾性分析,收集相关信息,包括基本情况、流行病学史、症状体征、临床分型、辅助检查结果等,分析其传播关系及传染性。结果单位聚集性病例平均潜伏期为(7.1±6.6)d,11例单位聚集性病例临床分型均为普通型;其中无症状病例5例,2例发热,2例咳嗽咳痰,2例咽痛咽干,血氧饱和度(SPO2)平均为98%;11例肺部影像学检查显示均有肺炎征象,双肺肺炎6例,单肺肺炎5例,典型毛玻璃样改变5例。结论新型冠状病毒肺炎人群普遍易感,密切接触者之间容易传播,单位集体宿舍要对住宿环境进行整体评估,人员之间进行有效隔离是防控疫情发展的重点。Objective According to a company's epidemic situation of 2019 coronavirus disease(COVID-19),COVID-19 population transmission characteristics were discussed,and guidance for residential environment of unit dormitory was given,so as to provide reference for the identification of COVID-19 in pre hospital emergency,and to improve awareness of protection and reduce infection rate.Methods Retrospective analysis was carried out on a group of confirmed cases transported by Beijing Emergency Center from February 27 to 29,2020.Relevant information was collected,including basic information,epidemiological history,symptoms and signs,clinical typing,auxiliary examination results,etc.,and the transmission relationship and infectivity were analyzed.Results The average incubation period of the patients with company aggregation was(7.1±6.6)days,and the clinical classification of 11 patients with unit aggregation was common type.There were 5 cases without symptoms,2 cases with fever,2 cases with cough and expectoration,2 cases with sore throat and dry throat,and the average SpO2 was 98%.The pulmonary imaging examination of 11 cases showed signs of pneumonia,6 cases with double lung pneumonia,5 cases with single lung pneumonia,and 5 cases with typical ground glass changes.Conclusion COVID-19 is generally susceptible,and easy to spread among close contacts.The overall dormitory environment should be assessed in a company dormitory.Effective isolation between personnel is the key to the prevention and control of the epidemic.
