目的 分析涡阳县新型冠状病毒肺炎确诊病例流行病学特征,为促进疫情防控能力建设的提升提供科学依据。方法 根据中国疾病预防控制信息系统-传染病监测系统中2020年1月23日~2月14日涡阳县网络报告的31例确诊病例监测数据和流行病学调查资料,采用描述性流行病学方法对新冠肺炎流行特征、流行病学史及传播风险等情况进行分析。结果 涡阳县共报告31例新型冠状病毒肺炎病例,无死亡病例。男女发病比例为1.07∶1;年龄5~78岁,其中20~60岁患者占总病例数的70.97%(22/31);农民患者占总病例数的54.84%(17/31);有武汉居住史7例,有武汉旅游史2例,确诊病例密切接触者发病22例。共发生6起聚集性疫情,聚集性病例23例(占总病例数的74.19%)。结论 涡阳县新型冠状病毒肺炎以20~60岁人群高发;所有病例暴露来源清楚;引起涡阳县新型冠状病毒肺炎聚集性疫情与武汉输入病例有关。
Abstract
Objective To analyze the epidemiological characteristics of confirmed COVID-19 cases in Guoyang county, so as to provide scientific basis for improving the capacity of epidemic prevention and control. Methods A total of 31 confirmed cases reported in Guoyang County from January 23 to February 6 in 2020 year in the Chinese information system for disease control and prevention were studied. Results The ratio of male to female was 1.07:1.The age distribution ranged from 5 to 78 years old, among which patients aged 20 to 60 years old accounted for 70.97% (22 cases) of the total cases.Farmer patients accounted for 54.84% (17 cases) of the total cases.There were 7 cases with living history in Wuhan, 2 cases with tourism history in Wuhan, and 22 cases with contact diagnosis.Eighteen patients were found when they came to the clinic after clinical symptoms, and the remaining 13 were all close contacts of the confirmed cases, which were found in the process of screening for fluid and nucleic acids.There were 6 clustered outbreaks, of which 23 were clustered (74.19% of the total number of cases).
