| 目的 调查分析两个家族发生家庭聚集性疫情的流行病学特征及其之间的关系，探讨新型冠状病毒肺炎（COVID-19）的传播方式，为有效开展疫情防控提供科学依据。方法 运用现场流行病学方法，调查内蒙古自治区包头市某旗两个家族不同家庭COVID-19疫情中病例及密切接触者，对流行病学调查资料和数据进行描述性分析。结果 该旗两个家族家庭聚集性COVID-19疫情的传染源为有湖北省武汉市洪山区居住史的确诊病例李某，父母被其感染成为确诊病例；杜氏家族杜某所在家庭的成员被李氏家族感染者传染，又因为多次家庭聚餐导致COVID-19在本家族内部多个家庭之间传播。两个家族共出现10例确诊病例，3例疑似病例。结论 COVID-19很容易在家庭内部传播，还可能在生活空间相对紧密的邻里实现传播，两个家族的病例之间有高度的关联性，同一单元邻居之间、同一家庭内部成员之间都应建立较强的防护意识，强化防控知识宣传教育和重点人群管控，避免COVID-19在邻里之间或家庭成员间发生传播。 |

Methods Field epidemiological investigation was conducted for the COVID-19 cases occurred in two families and the close contacts in a county of Baotou city in Inner Mongolia Autonomous Region. Descriptive statistical analysis on epidemiological data was conducted. Results The infection source of the COVID-19 cases in the two families was a man who had living history in Wuhan. After his return, his parents were infected by him. A few days later, the members of a neighbor family were found to be infected, and relatives of this family were also infected after dining together repeatedly. Finally, ten confirmed cases and three suspected cases of COVID-19 were detected in the two families. Conclusions Human-to-human transmission of COVID-19 can occur not only in a family but also in neighborhoods.
