南非的新冠病毒突变B.1.1529,会是大BOSS,还是普通感冒样?

南非政府定于当地时间25日发布这种新毒株的相关声明。非洲疾病预防控制中心表示,目前正与南非卫生官员联系,以了解新毒株及其对人的影响。科研人员警告称,新毒株存在大量突变,可能会通过躲避人体防御机制带来新一波疫情。

伦敦大学学院遗传学研究所所长Tom Peacock在一份发表的声明中说,南非和博茨瓦纳出现一种新冠病毒变体。这种名为B.1.1529的新变体带有异常多的突变。他说,新变体很可能是在一个免疫力低下新冠患者的感染程中演变出来的,可能是在一名未经治疗的艾滋病患者身上。B. 1.1529 变种,预计将被称为 Nu 菌株,于 11 月 11 日在非洲Botswana首次被发现。

南非国家传染病研究所在一份声明中说,南非已经检测到22起该变体。

为什么梅斯医学如此关注这种新型的突变呢?至少有以下一些原因:

1、B. 1.1529 变种是突变的集大成者

专家表示,这种新变种引起了南非的关注,对该变种的主要担忧是它具有大量突变。南非国家传染病研究所将于当地时间26日与世界卫生组织举行紧急会议。

2、B.1.1529感染能力可能大幅度上升

看看南非最近几天的病例变化,几乎是线性上涨。

3、delta病毒完全不敌B.1.1529

不仅如此,最令人担心的是delta病毒在这个新的突变面前,几乎不堪一击!

南非卫生部国家实验室(NHSL)的数据可以看出,砖红色的Delta本来占主导地位,但是,在蓝色的B.1.1.529冲击下,几乎不堪一击!

目前在香港,以色列等多国都已发现了B.1.1.529,而且部分检测试验盒无法很好检测出来,这会导致这种突变株更大范围的传播。我们近期会关注全球各地的病例变化,如果病例突然上升的话,可能就是这种新型的NU毒株了。

此前,科学家认为,delta毒株已经持续占优势很久了,其它一些毒株在delta下都未流行开来。如果delta持续不变的话,到明年夏天,病毒就基本能被很好地控制住。但是,如果B.1.1.529,全面取代delta的话,有可能再次造成一次全球性大流行。新冠病毒对抗就更任重而道远。

4、B. 1.1529 变种未来是BOSS还是普通感冒,未来15天见分晓

当然,病毒突变多,是风险,但也可能是好事。因为过度突变的话,也可能减弱其毒性(致病性),这次大的进化,是变成大BOSS,还是向普通感冒迈进,就在未来15天左右可以见分晓了。

未来只要看南非的重症病人的数量和比例,就知道这种新型变种的厉害了!
