Tracking SARS-CoV-2 variants​


All viruses, including SARS-CoV-2, the virus that causes COVID-19, change over time. Most changes have little to no impact on the virus’ properties. However, some changes may affect the virus’s properties, such as how easily it spreads, the associated disease severity, or the performance of vaccines, therapeutic medicines, diagnostic tools, or other public health and social measures.

WHO, in collaboration with partners, expert networks, national authorities, institutions and researchers have been monitoring and assessing the evolution of SARS-CoV-2 since January 2020. During late 2020, the emergence of variants that posed an increased risk to global public health prompted the characterisation of specific Variants of Interest (VOIs) and Variants of Concern (VOCs), in order to prioritise global monitoring and research, and ultimately to inform the ongoing response to the COVID-19 pandemic.

WHO and its international networks of experts are monitoring changes to the virus so that if significant mutations are identified, we can inform countries and the public about any changes needed to react to the variant, and prevent its spread. Globally, systems have been established and are being strengthened to detect “signals” of potential VOIs or VOCs and assess these based on the risk posed to global public health. National authorities may choose to designate other variants of local interest/concern.

Current strategies and measures recommended by WHO continue to work against virus variants identified since the start of the pandemic.


Naming SARS-CoV-2 variants​


The established nomenclature systems for naming and tracking SARS-CoV-2 genetic lineages by GISAID, Nextstrain and Pango are currently and will remain in use by scientists and in scientific research. To assist with public discussions of variants, WHO convened a group of scientists from the WHO Virus Evolution Working Group, the WHO COVID-19 reference laboratory network, representatives from GISAID, Nextstrain, Pango and additional experts in virological, microbial nomenclature and communication from several countries and agencies to consider easy-to-pronounce and non-stigmatising labels for VOI and VOC. At the present time, this expert group convened by WHO has recommended using labeled using letters of the Greek Alphabet, i.e., Alpha, Beta, Gamma, which will be easier and more practical to discussed by non-scientific audiences.



SARS-CoV-2 Variants of Concern and Variants of Interest, updated 31 May 2021​


Variants of Concern​

A SARS-CoV-2 variant that meets the definition of a VOI (see below) and, through a comparative assessment, has been demonstrated to be associated with one or more of the following changes at a degree of global public health significance:
  • Increase in transmissibility or detrimental change in COVID-19 epidemiology; or
  • Increase in virulence or change in clinical disease presentation; or
  • Decrease in effectiveness of public health and social measures or available diagnostics, vaccines, therapeutics.

Variants of Interest​

A SARS-CoV-2 isolate is a Variant of Interest (VOI) if, compared to a reference isolate, its genome has mutations with established or suspected phenotypic implications, and either:
  • has been identified to cause community transmission/multiple COVID-19 cases/clusters, or has been detected in multiple countries; OR
  • is otherwise assessed to be a VOI by WHO in consultation with the WHO SARS-CoV-2 Virus Evolution Working Group.

世卫改用希腊字母命名变种冠病病毒

依照新命名系统,

最早在英国发现的B117变种病毒将改称Alpha变种病毒,
最早在南非发现的B1351将改称Beta变种病毒,
最早在巴西发现的P1将改称Gamma变种病毒,
而最早在印度发现的B1617有两个分支——属于须关切变种的B16172将改称Delta变种病毒,
属于待观察变种的B16171将改称Kappa。

字母不一定够用,因为病毒会不断变异下去

我想看看自定义头衔到底能有多少字。继续加,看系统什么时候把这个字符串截断。呃,居然还有?那就继续吧。

为什么用希腊字母? 为什么不用甲乙丙丁、天干地支?
WHO看不起中华文化吗?希腊的GDP有中国高吗? 希腊有洲际导弹核潜艇吗?

英国科学家 Oliver Pybus甚至担心,地名命名所造成的烙印化甚至会阻碍防疫的进展。他对《自然》杂志表示: “ 我们最不希望看到的就是,有关国家不及时通报新发现的变种病毒。而地名命名方式恰恰会造成这种现象。”


病毒及其变种尽量使用地名命名的主要原因是避免污名化:Stigma,这种污名化经常是造成有关地区和国家延迟通报新发疫情的主要原因,人命关天,责任重大,只有那些低级趣味的无脑大嘴巴才会随口乱说,以此为乐。

1976年在非洲爆发埃博拉病毒到现在还没找到源头呢,也没见到把字母都用完了。

Wiki 上说在非洲爆发,怀疑源头在亚洲。

胡说八道。

这次新冠疫情,一开始在武汉爆发的时候, 是因为地名方式引发的隐报、瞒报吗? 当时报纸电视成片累牍的都在称呼“武汉肺炎”、“武汉病毒”。 根本没有在意这种地名命名方式。 还不是一样隐瞒到无法掩盖的地步,才扭扭捏捏的承认的 ?

掩盖就是掩盖, 隐瞒就是隐瞒, 这么做的理由大家都明白, 根本没有地名命名的事儿。
这帮白左天真派, 以为找到办法不用地名命名了, 各地就不再会有瞒报现象了? 这帮傻逼得有多天真才会这么想?

尽整些没用的,你要一说印度变种,都会紧张一下更小心点,说发现delta病毒,一片茫然。

叫Covid令人茫然了吗?一定叫武汉才能更小心?

世界专家都不如你们。

一听到英国变异很亲切,一听到印度变异很恐惧?


英国把变异隐瞒了3个多月。是因为怕以英国命名吗?

英国叫法和其他地方不同,称为肯特变种,大概是不愿意整个国家一起背锅。

加拿大这次lockdown主要是拜这个alpha变种所赐。
