摘　　要：目的了解河南省新型冠状病毒肺炎疫情地区特点,分析防控细节差异,为下一步城市和农村疫情防控提供参考。方法采用描述性流行病学方法,对2020年1月21日—3月8日河南省报告的新型冠状病毒肺炎病例分地区、分城市和农村等进行统计分析。结果截至2020年3月8日,河南省累计报告新型冠状病毒肺炎确诊病例1272例,死亡22例。全省18个地市均有确诊病例报告,波及全省147个县区(84.97%,147/173),596个乡镇街道(23.66%,596/2519)。信阳市、南阳市、驻马店市、郑州市、商丘市报告病例数和聚集性事件较多,为重点防控地区。聚集性事件250起,以家庭聚集(占85.20%)为主,21.60%的事件未找到明确传染源,以商丘市、平顶山市、郑州市占比高。城市病例613例(占48.19%),郑州市、平顶山市等6地市城市病例占比高;输入病例629例(占49.45%),驻马店市、开封市等6地市输入病例占比高。按输入病例构成比分为三类进行分析,无论在城市和农村中,还是在聚集和散发病例中,输入与本地构成比差异均有统计学意义。结论在总的防控策略不变的情况下,城市本身的居住、交通、商业往来等复杂特点,加之境外输入风险高,决定了需要采取更加精细化的防控措施;无症状感染者、轻症者难以被诊断和隔离,易造成传播,可开展血清学检测进行溯源和追踪接触者。Objective To understand the regional characteristics of coronavirus disease 2019(COVID-19) epidemic in Henan province, to analyze the differences in prevention and control details, and to provide references for the next step in epidemic prevention and control in urban and rural areas. Methods According to different regions, cities and villages, descriptive epidemiological methods were used for statistical analysis of COVID-19 cases reported in Henan province from January 21 to March 8, 2020. Results As of March 8, 2020, 1,272 confirmed cases and 22 deaths of COVID-19 were reported accumulatively in Henan province. Confirmed cases were reported in 18 prefecture-level cities of the province, affecting 147 counties or districts(84.97%, 147/173) and 596 township streets(23.66%, 596/2,519). Xinyang city, Nanyang city, Zhumadian city, Zhengzhou city and Shangqiu city reported more cases and clustered events and were considered as the key prevention and control areas. There were 250 clustered events, and most of them were family gathering(accounting for 85.20%). 21.60% of the clustered events did not find a clear source of infection, of which Shangqiu city, Pingdingshan city and Zhengzhou city accounted for a high proportion. 613(48.19%) cases were found in cities, with a high proportion of cases in 6 prefecture-level cities such as Zhengzhou city and Pingdingshan city. 629(49.45%) imported cases were reported, with a high proportion of cases in 6 prefecture-level cities such as Zhumadian city and Kaifeng city. According to the constituent ratio of the imported cases, the 18 prefecture-level cities were divided into three types of regions for performing the analysis, and statistically significant differences were found in the constituent ratios of the imported cases and the local cases between urban and rural areas as well as between aggregated and sporadic cases. Conclusions Under the condition that the overall prevention and control strategy remains unchanged, the complex characteristics of cities themselves such as r
