Abstract

[Objective] To explore the transmission pattern of novel coronavirus pneumonia (NCP) in the population by describing an imported case of novel coronavirus infected pneumonia epidemic situation. [Methods] Using the method of field investigation, epidemiological investigations were carried out for the imported NCP case and the close contacts related to this epidemic cluster. Data were collected such as the date of onset, isolation of the case and the close contacts. The novel coronavirus nucleic acid was collected from the throat swabs of the case and the close contacts. These samples were detected by real-time fluorescence quantitative RT-PCR. [Results] In this epidemic cluster, the imported NCP case introduced to Yangzhou had effected 36 people (12 people in the family and 24 people outside the family) and 2 people in the family were diagnosed as asymptomatic infections. [Conclusion] In the process of transmission, NCP mainly exists in respiratory droplets and close contact transmission, which is easy to cause family aggregation epidemic. Key words: novel coronavirus infected pneumonia; family aggregation epidemic; epidemiological investigation

扬州市首次家庭聚集性新型冠状病毒肺炎流行病学调查

[目的]通过描述一起输入性新型冠状病毒感染的肺炎疫情，探讨新型冠状病毒肺炎(NCP)在人群中的传播模式。[方法]采用现场调查的方法，对输入性新型冠状病毒感染病例及与该聚集性疫情有关的密切接触者进行流行病学调查。收集了发病日期、病例隔离情况和密切接触者等数据。从病例及密切接触者的咽拭子中采集新型冠状病毒核酸。采用实时荧光定量RT-PCR检测。[结果]本次聚集性病例中，输入性新型冠状病毒感染病例36人(家庭内12人，家庭外24人)，家庭内2人确诊为无症状感染者。[结论]在传播过程中，新型冠状病毒主要存在于呼吸道飞沫传播和密切接触传播中，容易引起家庭聚集性流行。关键词:新型冠状病毒感染的肺炎;家庭聚集性流行病;流行病学调查（流调）
