SARS-CoV-2再变种下去，希腊字母都快不够用了。

WHO也不是啥都不干的，看看，命名病毒变种也是重要的工作：

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 (now called the Technical Advisory Group on Virus Evolution), 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 letters of the Greek Alphabet, i.e., Alpha, Beta, Gamma, Delta which will be easier and more practical to be discussed by non-scientific audiences.

虽然希腊字母也有24个，现在一下子就跳到第十五个了，下次再来个变种，就不能再跳了，字母也得省着点花。

顺便复习一下希腊字母：

The uppercase and lowercase forms of the twenty-four letters are:

Α α,Β β, 

Γ γ, Δ δ, 

Ε ε, Ζ ζ,

 Η η, Θ θ, Ι ι, 

Κ κ, Λ λ, 

Μ μ, Ν ν, 

Ξ ξ, Ο ο, 

Π π, Ρ ρ, 

Σ σ/ς, Τ τ, 

Υυ, Φ φ, 

Χ χ, Ψ ψ,

and Ω ω.

• 可以用正式名称而不是简称，譬如Omicron的正式名称是B.1.1.529。 -Porcelana- ♀ (0 bytes) () 12/29/2021 postreply 08:17:28
