摘要/Abstract

摘要： 目的通过对济南市某商城新型冠状病毒肺炎聚集性疫情进行分析,探讨可能的传播链条,为下一步防控提供数据支持。方法对确定的8例与济南市某商城相关的新型冠状病毒肺炎病例开展流行病学调查,结合与医生、家属访谈信息,建立Excel数据库,并进行描述性统计分析。结果 8例与某商城相关的新型冠状病毒肺炎病例中,4例为员工、2例为顾客、2例为员工家属。 5例因症就诊者从发病到首次就诊平均经历4.8 d。8例病例分布在3个小区,4名员工中3例为同柜台同事,另1例为商城不同层的员工。共确定密切接触者777人,其中家庭成员35人、商城工作人员736人、顾客6人。每例病例密切接触者平均为97人。结论商场内聚集性疫情密切接触者数量多,波及范围广,控制难度大;新型冠状病毒感染能够有效人传人,呼吸道飞沫及密切接触是主要传播方式;应重视职工健康申报和因病休假,禁止带病上岗。

Abstract: Objective To analyze a cluster outbreak of COVID-19 associated with exposure to a shopping mall in Jinan City, investigate the possible transmission chain, and provide reference for further prevention and control. Methods An epidemiological survey was conducted on 8 COVID-19 cases associated with a shopping mall, patients family members were interviewed, and data extracted were entered into an excel database for descriptive statistical analysis. Results Of the 8 cases, 4 were employees in a shopping mall, 2 were customers, and 2 were employees family members. The average time from onset to the first visit of 5 patients was 4.8 days. The patients lived in 3 different communities. Three of the four employees worked at the same counter, and one worked on another floor in the mall. A total of 777 close contacts were identified, including 35 family members, 736 employees in the mall and 6 customers. The average number of close contacts per case was 97. Conclusion The cluster outbreak in the shopping mall involves a wide range and large number of close contacts, so it is difficult to control. COVID-19 can be transmitted from person to person, and respiratory droplets and close contact are the major ways of transmission. During COVID-19 epidemic, due attention should be paid to employee’ health declaration and sick leave in order to avoid transmission in work place.

Key words: COVID-19, Cluster outbreak, Close contacts, Transmission chain
