A Nomenclature For The Coronavirus Variants. Novel Knowledge Of Common Use

 

The naming of variants of SARS-CoV-2 has been a bit slapdash. Different databases that share the sequences of the virus have different nomenclature norms. For instance, the variant that emerged in the United Kingdom is called B.1.1.7 on the Pango platform, but is called 20I/S:501Y.V1 on Next Strain. Yesterday, the World Health Organization (WHO) announced that SARS-CoV-2 variants of interest (VOI) and variants of concern (VOC) will be named based on the Greek alphabet for purposes of public discourse.

 

As B.1.1.7 was the first VOC designated by WHO, it is called Alpha under the new naming system. B.1.351, which originated in Brazil, is now called Beta. The two other VOCs are P.1, the variant first identified in Brazil and now referred to as Gamma, and B.1.617.2 that originated in India, now called Delta. The six VOIs designated by WHO take up Epsilon through Kappa in the Greek alphabet. The full list will be maintained on WHO´s website.

 

According to WHO, the technical variant names are too confusing for the general public and so “people often resort to calling variants by the places where they are detected, which is stigmatizing and discriminatory.”

 

“I heard it’s sometimes quite a challenge to come to an agreement with regards to nomenclature,” Frank Konings, the leader of the working group, tells STAT. “This was a relatively straightforward discussion in getting to the point where everybody agreed.”
