Abstract
Objective: To describe the epidemiological characteristics of a cluster of COVID-19 cases reported in Baodi district of Tianjin as of 18 February, 2020, which might be associated with the exposure in a local department store, and provide suggestions for prevention and control strategy development. Methods: The basic characteristics, time and area distributions, clinical manifestations, epidemiological history and transmission mode of the COVID-19 cases associated with the department store exposure were analyzed. Results: A total of 40 COVID-19 cases were associated with the department store exposure, accounting for 75.47% of the total confirmed cases (53 cases) reported in Baodi district. The cases were mainly at the age of 60 years or older (35.00%) and farmers (40.00%). The main clinical manifestations included fever (95.00%), cough (35.00%), and diarrhea (15.00%). The proportion of confirmed severe cases was 32.50%. The incidence curve showed that the incidence peak occurred on 31 January, 2020. Among the 40 cases, 6(15.00%) were department store employees, 19(47.50%) were customers and 15(37.50%) were close contacts (secondary cases). The first case occurred on 21 January, 2020, this case was a department store employee who had a purchasing history at whole sale markets in other provinces and cities before the onset, and 3 employees were still on duty after symptom onsets. The median of the incubation period of customer cases was 6 days, and the median of the interval between onset and medical treatment of customer cases was 7 days. Conclusion: This was a cluster epidemic of COVID-19, which might be associated with the exposure in the department store. By now, the current prevention and control measures have achieved satisfied effects.

某百货大楼关联病例40例，占辖区确诊病例数（53例）的75.47%，发病主要分布在≥60岁（35.00%）；职业以农民为主（40.00%）；临床表现主要为发热（95.00%），其次为咳嗽（35.00%），存在腹泻（15.00%），确诊重型比例为32.50%；流行曲线显示发病高峰出现在1月31日。聚集性疫情中涉及一代病例百货大楼员工6例（15.00%）、顾客19例（47.50%），二代密切接触续发病例15例（37.50%）；最早发病员工1月21日发病，潜伏期内有外省市批发市场进货史，有3名员工发病后在岗工作；顾客发病潜伏期平均为6 d，发病就诊间隔7 d。 <b>结论：</b> 此次宝坻百货大楼关联病例为一起新型冠状病毒肺炎聚集性疫情，可能与宝货大楼暴露有关,目前采取防控措施后已取得阶段性效果。.</AbstractText></OtherAbstract><KeywordList Owner="NOTNLM"><Keyword MajorTopicYN="N">COVID-19</Keyword><Keyword
