摘要
目的分析河南省新型冠状病毒肺炎(NCP)的流行病学特点,为河南省NCP的防控决策提供证据支持。方法收集河南省及省内各地市卫生健康委员会官方疫情信息、省内官方媒体及新媒体报道,整理、汇总省内各地区新型冠状病毒肺炎病例信息,采用描述性统计方法,分析我省新型冠状病毒肺炎疫情发生发展的流行病学特点和病例特点。结果截止至2020年2月7日,河南省累计确诊病例981例,累计密切接触者20928例,累计医学观察者10187例。患者年龄主要集中于19~60岁,约占81.75%;男性患者比例略高于女性(54.09%vs.44.58%);发热为新型冠状病毒肺炎的主要症状,近一半的患者在3天之内得到确诊;56.31%的患者有武汉旅居史,24.23%和8.63%的患者有接触确诊病例史和接触疑似病例史,仅14.93%的患者在发病前接受隔离观察;39.38%的患者在确诊前进行过0~1次的就诊,57.74%的患者居住地位于城区。结论河南省新型冠状病毒肺炎病例大多数为输入性病例,春运期间人员流动是影响疫情发展的主要因素。实施严格的隔离政策可有效控制疫情发展。
