　　摘 要 目的：分析~鼓县一起新型冠状病毒肺炎家庭聚集性疫情，为新型冠状病毒肺炎防控提供参考。方法：采用描述流行病学调查方法进行调查分析。结果：本起聚集性疫情导致8个家庭16人染病，一代指示病例在1月22日从厦门返乡高铁上感染新型冠状病毒，通过共同生活感染了3名家庭成员，通过多次聚餐传给了3位亲戚，其中二代指示病例又通过频繁聚餐聚会传染了9名三代病例。本起疫情最长潜伏期中位数7 d，首发病例发病-就诊间隔4 d、就诊-确诊间隔7 d。结论：输入来源变化，患者就诊延迟，医疗机构发现延迟，社区防控措施不落实，造成了此起聚集性疫情，提示今后应建立健全风险评估机制、发热病人院前监测机制，提高医疗机构“四早”能力，强化社区防控措施。

　　ABSTRACT Objective： To analyze a family cluster epidemic of COVID-19 in Tonggu County， and to provide a reference for prevention and control of the COVID-19 epidemic. Methods： Descriptive epidemiological investigation was made on the investigation and analysis. Results： The cluster epidemic caused 16 people in 8 families to be infected. First generation indicator case was infected with New Coronavirus on the high-speed railway returning home from Xiamen in January 22nd. Three family members were infected through living together， three relatives were infected by having the same meals with him， and among them， the second generation indicator cases infected 9 third-generation cases through frequent dinner parties. The median of the longest incubation period of the epidemic was 7 days， the interval between onset and visit of the first case was 4 days， and the interval between visit and diagnosis was 7 days. Conclusion： Changes in input sources， delays in patient visits， delays in discovery by medical institutions， and failure to implement community prevention and control measures have resulted in this cluster epidemic， which is suggested that in the future， we should establish and improve the risk assessment mechanism and pre hospital monitoring mechanism for fever patients， improve the “four early” ability of medical institutions， and strengthen community prevention and control measures.
