摘要
目的阶段性分析新型冠状病毒肺炎(以下简称"新冠肺炎")境外输入性病例的形势和特点,为制订防控策略提供参考。方法收集2020-02-26/11-30网络公开新闻、国家卫生健康委员会、各省(市、区)卫生健康委员会网站公布的境外输入性新冠肺炎病例情况并进行统计学描述。结果2020-02-26/11-30共公布境外输入性病例3866例。4月出现月累计病例数量环比峰值,俄罗斯输入疫情明显。8月出现新增病例数量环比峰值。病例主要集中在上海市、广东省、黑龙江省、四川省、陕西省和内蒙古(70.28%)。数据显示输入来源国主要是俄罗斯、英国、美国、菲律宾、西班牙、法国和阿联酋(56.62%)。英国输入主要流向上海市、北京市和广东省,俄罗斯输入主要流向黑龙江省、内蒙古自治区、陕西省和山西省。埃及输入主要流向四川省。美国输入主要流向上海市、北京市和广东省。上海市境外输入病例数居高,陕西省和四川省境外输入病例上升较快,北京市和黑龙江省疫情趋于缓和。结论国家出台相应防控政策有效缓解疫情,但是全球疫情形势严峻,境外输入性病例持续增多。众多调控因素造成境外输入性疫情在省份之间形势差异较大。输入性病例引起的国内局部地区聚集性疫情不容忽视,疫情风险较大的地区应继续严格落实就地集中隔离和核酸检测等措施,防范疫情复发。
