摘要
目的:分析重庆医科大学附属永川医院的90例新型冠状病毒肺炎(coronavirus disease 2019,COVID-19)病例的流行病学特征,为制定和实施有针对性的COVID-19防控措施提供依据。方法:以2020年1月21日至2月20日该医院收治的90例COVID-19确诊病例为研究对象,收集其流行病学资料和临床资料,对病例的人群分布、地区分布、时间分布、临床特征等进行描述性分析。结果:自1月21日确诊渝西首例病例,截至2月20日,渝西8个区县均有病例,共90例。2月1日为发病高峰,单日最高9例,随后逐渐下降。有疫区居住、旅游史的病例占36.67%(33/90);与曾到过疫区的人员有密切接触的病例占63.33%(57/90),存在聚集性发病。男女比为1.37∶1;最小年龄3岁,最大年龄89岁,平均年龄(48.15±17.63)岁,年龄集中在40~50岁。危重型及重型病例占13.33%(12/90),普通型及轻型病例占86.67%(78/90);无死亡病例。结论:COVID-19人群普遍易感;病例年龄主要集中在40~50岁,以轻型和普通型为主。渝西地区防控措施得当,COVID-19疫情进入低水平散发状态;随着复工、复产及复学等,人口流动、聚集增加,建议持续有效防控、精准防控,防治疫情反弹。
Objective:To analyze the epidemiological characteristics of 90 cases of coronavirus disease 2019(COVID-19)in Yongchuan Hospital of Chongqing Medical University,and to provide an evidence for COVID-19 to formulate and implement targeted prevention and control measures.Methods:Ninety cases of COVID-19 confirmed patients admitted to a designated hospital in Chongqing were taken as the research object from January 21st to February 20th,2020 and the epidemiological and clinical data were collected.The population distribution,regional distribution and time distribution of the cases were collected.And clinical characteristics.Results:The first case was diagnosed in western Chongqing since January 21.As of February 20,there were cases in eight districts and counties in western Chongqing,with a total of 90 patients.The peak onset occurred on day 2-1,with a maximum of 9 cases per day,and then gradually decreased.36.67%(33/90)of the cases have a history of living and traveling in the epidemic area;63.33%(57/90)have close contact with people who have been to the epidemic area,and there is a cluster of cases.The male-to-female ratio was 1.37∶1;the minimum age was 3 years old and the maximum age was 89 years old.The average age was(48.15±17.63)years old,and the age was concentrated between 40 and 50 years.Critical and severe cases accounted for 13.33%(12/90),ordinary and light cases accounted for 86.67%(78/90);there were no deaths.Conclusion:The COVID-19 population is generally susceptible;the number of cases is concentrated in 40-50 years old,mainly light and ordinary.The prevention and control measures in the western Chongqing area are in place,and the COVID-19 epidemic has entered a low-level epidemic situation.With the resumption of work,resumption of production,and resumption of schooling,population movements and clusters may increase.It is recommended that continuous effective prevention and control,precise prevention and control be implemented,and the epidemic situation rebound.
