摘　　要：目的调查分析上海市宝山区一起新型冠状病毒肺炎(简称新冠肺炎,COVID-19)家庭聚集性疫情流行病学特征。方法采用现场流行病学方法调查一起家庭聚集性新冠肺炎疫情中的病例及密切接触者,对流行病学调查资料进行描述性分析,采用实时荧光定量RT-PCR方法对采集的标本进行新型冠状病毒核酸检测。结果该起家庭聚集性疫情涉及A、B两个家庭11人,其中6人发病,罹患率54.55%。指示病例(A1)发病前接触过同工作单位的确诊病例,后通过家庭生活传给病例父母(病例A2和A3);病例A3与邻居B1日常接触,导致病例B1家庭(病例B1、B2和B3)陆续发病。结论新型冠状病毒传染性强且人群普遍易感,易在家庭内传播,需加强密切接触者的追踪与管理。Objective To investigate and analyze the epidemiological characteristics of a family cluster of COVID-19 in Baoshan District of Shanghai Municipality.Methods Field epidemiological methods were used to investigate the cases and close contacts of a family cluster of COVID-19.The epidemiological data were descriptively analyzed.Real-time fluorescent quantitative RT-PCR was employed to detect 2019-nCov nucleic acid in the specimens collected.Results Eleven persons from families A and B were involved in this family cluster of COVID-19,and 6 of them had attacked,with the incidence rate of 54.55%.The indicator case(A1)of the family cluster had contacted the confirmed cases working at the same unit before the onset of the disease,and then parents(cases A2 and A3)of the case A1 were infected through family life.The case A3 had daily contact with her neighbor B1,resulting in the disease onset in the B1’s family(cases B1,B2 and B3).Conclusions The 2019-nCov was highly infectious and easily spread within families.It is necessary to strengthen the tracing and management of close contacts.
