摘要
目的为了解新型冠状病毒肺炎的流行病学特征,科学指导全省下一步防控工作。方法选取截至2020年3月31日湖北省传染病报告信息管理系统中进行网络报告的所有新型冠状病毒肺炎病例,对病例的发病流行曲线、年龄性别特征、时空特征进行分析。结果截至2020年3月31日全省累计报告新冠病例70764例,其中确诊病例49195例。全省累计报告新冠死亡病例4579例,报告病死率为6.47%。本次疫情的发病高峰在1月20日至2月14日。确诊病例男女性别比为0.99∶1,年龄集中在30~69岁之间。1月5日之前确诊病例主要为武汉市报告,1月6日至1月31日全省各县区报告新冠确诊病例发病率开始上升,约50%以上的县区陆续报告确诊病例发病率在10/10万以上,2月1日至15日全省新冠确诊病例发病率快速上升,2月16日以后全省各县区新冠确诊病例发病率逐渐上升至平台期。在全国支援武汉市和湖北省、新建医院和方舱、征用隔离点等强力措施下,在湖北省采取的突出救治和隔离(四早、四集中、应检尽检、应收尽收、应治尽治)、限制人员流动(交通管控和检疫、延长春节假期)、减少接触(居家、小区管控),加强风险沟通,做好日常防护(戴口罩、勤洗手等)等防控措施取得明显效果。结论湖北省武汉市首先发现并报告新冠肺炎疫情,发病高峰在1月20日至2月14日,重点人群为30~69岁年龄组人群。此次新冠暴发疫情在举国体制支持的综合防控措施下得以有效控制。
