美国疾病控制和预防中心网站5日更新的疫情数据显示,在截至4日的一周,美国平均单日新增病例数超过4.1万例。其中,10月2日单日新增确诊病例50160例,这是继9月25日之后,美国单日新增病例再次超过5万例。

死亡病例数方面,美国累计死亡病例9月22日超过20万例之后,每周平均单日新增死亡病例数维持在700例左右。不过在9月30日,疾控中心报告单日新增死亡病例超过1000例。

8月底以来,全美新冠疫情比7月中旬峰值时期趋于缓和。但自9月中旬起,疫情又有抬头趋势。据美国有线电视新闻网报道,过去一周,美国有22个州单日新增确诊病例数较前一周上升。

美国儿科学会和儿童医院协会联合发布的最新报告显示,自新冠疫情暴发以来,美国已有超过62万名儿童确诊感染新冠病毒,且近期儿童感染病例数快速增加。

据《纽约时报》报道,近期确诊病例激增地区主要是美国中西部和西部地区。高校复学是一个重要因素。自疫情开始以来,美国高校已报告超过13万例新冠确诊病例和超过70例死亡病例,其中大部分确诊病例是秋季复学后报告的。

美疾控中心日前发布的一份研究报告说,8月2日至9月5日,全美18岁至22岁的年轻群体中感染新冠病毒的人数增加了55%,其中东北部和中西部地区增幅高达144%和123%。

疾控中心说,包括高校学生在内的年轻群体应切实遵循相关防疫措施,包括戴口罩、保持社交距离、勤洗手等,以尽量减少新冠病毒传播。
