摘　　要：目的2020年1月24日至2月11日,济南市已报告新型冠状病毒肺炎确诊病例47例.截至2月25日24时,济南市已连续14 d无新型冠状病毒肺炎确诊病例报告.分析现阶段济南市疫情动态和流行特征,为今后疫情防控工作提供参考.方法描述性分析济南市现阶段确诊病例的人口学特征、临床特征、流行病学特征,识别家庭聚集性.结果济南市47例新型冠状病毒肺炎确诊病例中,临床普通型为主(74.5%),临床治愈出院24例(51.1%),无死亡病例发生.首发症状发热为主(66.0%),CT诊断多为双侧肺炎(82.1%).病例性别分布男女相近,年龄集中在20~59岁(70.2%),中心城区居多(83.0%).40.4%病例发病前有武汉暴露史.发病呈明显的家庭聚集性,共发生10起家庭聚集性疫情累及病例33例,占已报告病例总数的70.2%,其中5起由武汉暴露导致.结论济南市疫情防控工作取得阶段性效果,防止周边及疫情高发地区的病例输入风险仍是济南市今后疫情防控工作的重点.Objective There were 47 confirmed cases of coronavirus disease 2019(COVID-2019)reported in Jinan City from January 23 to February 11,2020.Since February 25,2020,there were no confirmed cases reported in Jinan City for 14 consecutive days.In order to provide reference for future epidemic prevention and control,we analyzed the current epidemic situation and epidemiological characteristics.Methods The demographic,clinical and epidemiological characteristics of confirmed cases in Jinan City were evaluated with descriptive analysis and family clusters were traced.Results 74.5%of 47 confirmed cases were clinical common type,and 24(51.1%)were cured and discharged.No death occurred.Fever(66.0%)was the first dominant symptom.CT showed 82.1%of the cases were bilateral pneumo-nia.The distribution of cases was similar between male and female.Most patients(70.2%)aged 20 to 59 years,83.0%lived in the central urban area,and 40.4%had a history of Wuhan exposure before onset.Five of 10 family cluster out-breaks were sourced from Wuhan exposure.70.2%(33 cases)of 47 cases were related to the family cluster outbreaks.Conclusion The epidemic prevention and control work in Jinan City has achieved phased results.Preventing importa-tion from surrounding areas and high incidence risk areas is still the focus of future efforts.
