截至北京时间2022年2月6日7时01分,Worldometers世界实时统计数据显示,全球累计确诊新冠肺炎COVID-19)病例超过3亿9355万例,新增2,214,964例,达到393,554,762例。累计死亡病例575.1万例,达到5,751,829例。新增死亡为8,317例。康复为312,643,874例,重症和危重症病人达到91,180例;全球新冠确诊病例超过100万例的国家达50个,120个国家病例超10万例。昨日报道:2022年2月5日简报:国际知名医学专家认为奥密克戎不再是威胁,全球重症人数持续下降;美国疫情已大幅下降;日本东京无症状感 染者人数大幅增加;英国约有133万人正在经历“长新冠”

香港新增351宗新冠病毒确诊案例

香港特区政府食物及卫生局局长陈肇始5日下午在记者会上公布,截至当天零时,香港新增351宗新冠肺炎确诊案例,是两年来单日新高。

据介绍,新增案例中343宗为本地个案,8宗为输入个案。另外还有200宗初步阳性个案。本地案例中,大部分怀疑感染变异病毒奥密克戎,另有超过20宗怀疑涉及德尔塔病毒。

陈肇始表示,目前香港疫情非常严峻,农历新年假期期间,市民参加节日活动、社交接触,已引发新的感染群组,特区政府将采取多项措施应对,包括大幅提升检测能力、增加隔离检疫设施,以及有需要时市民须进行14日居家检疫。

土耳其总统埃尔多安新冠检测结果为阳性

土耳其总统埃尔多安当地时间2月5日在其社交账号上确认,在出现轻微新冠肺炎症状后,其与夫人的新冠检测结果呈阳性,并确认感染的是奥密克戎毒株。目前正在家隔离,居家办公。

美国猴子试验发现 或将不再需要研发奥密克戎疫苗

据欧联通讯社报道,美国政府研究人员4日表示,根据一项针对猴子的研究结果显示,莫德纳(Moderna)疫苗加强剂与针对奥密克戎(Omicron)变异毒株的疫苗相比,两者的保护力差异不大。或将不再需要研发针对奥密克戎变异毒株的疫苗。

美国国家过敏和传染病研究所(NIAID)研究员向猴子接种两剂莫德纳疫苗后,再分别接种莫德纳加强剂及奥密克戎疫苗。结果显示,两种加强剂都对包括奥密克戎在内的所有高关注变异株产生了,可比较且显著增加的中和抗体反应。

研究人员测试了动物免疫反应的各个方面,并让它们接触病毒。研究发现,根据这项在同行评审前发布在bioRxiv上的研究,这两种增强剂对包括奥密克戎在内的所有令人担忧的变异体都产生了,相当且显著的中和抗体反应增加。

以色列可能是“感染率最高的国家”

以色列最近却得到了世界上“感染率最高的国家”的称号。以色列先后经历了阿尔法变异病毒,另一波德尔塔变异浪潮,现在是奥米克戎病毒。

以色列卫生部2月5日晚间通报,在过去24小时,新增37977例新冠肺炎确诊病例;新增死亡病例23例。目前,以色列全国活跃病例总数达到370798例。在2805名住院治疗患者中,1213人病情严重,370人病情危重。以色列再次感染新冠肺炎的情况越来越普遍,在所有确认的康复者中有6.53%的人至少又一次新冠检测呈阳性。与此同时,感染系数(不包括未报告的家庭抗原检测阳性病例)已降至0.88,似乎表明以色列的奥密克戎疫情正在减弱。
