Epidemiological features and prevention measures of COVID-19 in high incidence areas of Henan Province

目的:分析河南省新型冠状病毒肺炎高发地区(信阳市、郑州市、南阳市、驻马店市)新冠肺炎的流行病学特征以及当地防控措施。方法:根据河南省及4市的卫生健康委官方网站搜集新冠肺炎确诊病例资料,进行统计描述与分析。结果:截至2月24日24时,河南省、信阳市、郑州市、南阳市、驻马店市新冠肺炎累积发病率分别为1.32/10万、4.23/10万、1.55/10万、1.55/10万、1.97/10万,4市确诊病例中男女比分别为1.38∶1、1.14∶1、0.74∶1、1.53∶1。确诊病例年龄为15~64岁。本地病例占比随时间波动上升,驻马店市输入型病例占比(70.5%)居4市首位。信阳市和南阳市确诊病例平均潜伏期分别为9.5 d、10.0 d,信阳市确诊病例发病后平均就诊时间为4.7 d。信阳市(87.6%)、驻马店市(78.3%)确诊病例首次就诊以二级医院为主,郑州市(88.9%)、南阳市(98.7%)确诊病例以二级、三级医院就诊为主。郑州市、驻马店市、信阳市确诊病例就诊后平均确诊时间分别为3.6 d、3.4 d、3.3 d,信阳市确诊病例发病后平均确诊时间(8.0 d)高于南阳市(5.5 d)。疫情发生后,河南省及新冠肺炎高发区采取了以社区(包括城市社区和村)防控为主的综合防控措施。结论:本文梳理并分析了河南省疫情高发区新冠肺炎确诊病例的基本情况、性别年龄分布、患者行为等流行病学特征以及当地主要防控措施,为进一步的疫情防控工作提供参考依据。

Objective:To describe the epidemiological features and prevention measures of COVID-19 in Xinyang City,Zhengzhou City,Nanyang City,Zhumadian City of Henan Province.Methods:The data of COVID-19 confirmed cases were collected from the official websites of Henan province and the four cities.Statistical description and analysis were conducted.Results:By 24:00 on February24,2020,the cumulative incidence rates of COVID-19 in Henan province,Xinyang City,Zhengzhou City,Nanyang City,and Zhumadian City were 1.32,4.23,1.55,1.55,and 1.97 per 100000 population,respectively.The proportion of men to women in the confirmed cases in the four cities was1.38:1,1.14:1,0.74:1,and 1.53:1,respectively.The confirmed cases were mainly in 15~64 years old groups.The proportion of local cases increased along with time,and the proportion of imported cases in Zhumadian City was 70.5%,ranking the first among the four cities.The average incubation period in Xinyang City and Nanyang City was 9.5 days and 10.0 days respectively.The average time interval between the onset and going to a doctor was 4.7 days in Xinyang City.In Xinyang City(87.6%),Zhumadian City(78.3%),the first visit hospital of confirmed cases was mainly in level2,while in Zhengzhou City(88.9%)and Nanyang City(98.7%),level 2 and level 3 were the main levels.The average time interval between going to a doctor and diagnosis in Zhengzhou City,Zhumadian City,and Xinyang City was 3.6 days,3.4 days,and 3.3 days respectively.The time interval between the onset and diagnosis in Xinyang City(8.0 days)was longer than that in Nanyang City(5.5 days).Henan province and the four cities adopted comprehensive prevention and control measures focusing on community(including urban communities and villages).Conclusion:The epidemiological features of COVID-19 cases in Xinyang City,Zhengzhou City,Nanyang City,Zhumadian City of Henan province,including the basic situation,gender and age distribution and patient behavior,and the main preventive measures adopted were reviewed and analyzed in this paper,and it provides references for prevention and control of COVID-19.
