摘要/Abstract

摘要： 目的了解新冠肺炎聚集性疫情流行特征,为下一步防控策略提供依据。方法采用普查的调查方法对2020年1月24日至2月11日报告的济南市37例新型冠状病毒肺炎聚集性病例的人口学、危险因素暴露史、传播力、就医服务和临床症状等流行特征进行横断面研究。结果济南市新冠肺炎聚集性疫情共有9起,首发病例中8例有湖北武汉相关危险因素暴露史,潜伏期中位数为9 d,传染人数中位数为3人,接触方式以共同居住为主。临床病例分型以普通型为主。25例已经治愈并出院。结论新冠肺炎病毒传播力较强,济南市新冠肺炎聚集性疫情多以近距离接触传播引起。建议要继续坚持综合防控措施,控制新冠肺炎疫情的传播。
