The World Well being Organisation on Monday introduced that COVID-19 variants are to be identified by letters of the Greek alphabet. The B.1.617.1 and B.1.617.2 variants of COVID-19 , first recognized in India, have been named as ‘Kappa’ and ‘Delta’ respectively.

With quite a few variants of the novel coronavirus having emerged worldwide, individuals in every single place have struggled to maintain observe of their advanced alphanumeric names. The casual various in lots of circumstances has been to establish variants in accordance with the locations the place they have been first seen. Nevertheless, this methodology has raised considerations over its potential to result in stigma towards nations or areas.

It’s for these causes that the WHO has introduced the brand new names. Maria Van Kerkhove, the WHO’s technical COVID-19 lead, tweeted on Monday —

The WHO’s transfer got here practically three weeks after India objected to the B.1.617 mutant of the novel coronavirus being termed an ‘Indian Variant’ in media experiences with the Union well being ministry mentioning that the UN’s high well being organ has not used the phrase “Indian” for this pressure in its paperwork.

New nomenclature

The brand new system applies to variants of concern — probably the most troubling of which 4 are in circulation — and the second-level variants of curiosity being tracked, as reported by AFP.

Beneath the brand new system, the variants of concern tackle the next names: the hitherto so-called British variant B.1.1.7 turns into Alpha; the B.1.351 first found in South Africa turns into Beta, whereas the Brazilian P.1 turns into Gamma.

The lineage names corresponding to B.1.1.7.2 will nonetheless proceed for use in scientific circles, for the mutation data that their identify conveys.

“Whereas they (lineage names) have their benefits, these scientific names may be tough to say and recall, and are liable to misreporting,” the WHO mentioned in a press release.

“In consequence, individuals typically resort to calling variants by the locations the place they’re detected, which is stigmatising and discriminatory. To keep away from this and to simplify public communications, WHO encourages nationwide authorities, media retailers and others to undertake these new labels,” the highest UN well being physique mentioned.

The WHO has been attempting to provide you with simplified new nomenclature for the variants for a number of months.

The Greek alphabet incorporates 24 letters however there isn’t a plan but as to the place to go subsequent if they’re exhausted. Epsilon, Zeta, Eta, Theta and Iota have already been ascribed to variants of curiosity.

Historic perspective

The COVID-19 pandemic is probably the primary time that variants of the identical illness are getting widespread public consideration. Nevertheless, the method of naming ailments and pathogens has typically been fraught with controversy.

Traditionally, viruses have typically been related to the places from which they’re thought to have emerged corresponding to Ebola, which is called after the Congolese river of the identical identify.

However this may be damaging for the locations and sometimes inaccurate corresponding to with the so-called ‘Spanish flu’ pandemic of 1918 whose origins are unknown.

Additional, these norms of naming ailments after locations haven’t all the time been constant. An article in The Quint has quoted well being methods skilled Chandrakant Lahariya as saying, “We all know that for lengthy, these ailments and viruses have been named after town or locations the place they (are mentioned to have) originated from…However one of many main watershed (moments) got here in 2009 when Swine Flu – H1N1 – was initially being reported within the US, Canada and another components. So if the identical conference would have been adopted, then it ought to have been referred to as ‘American Flu’. However as you recognize, persons are actually good, in order that they shortly moved to name it Swine Flu. So it’s very handy – the one who wields the ability determines the naming of the ailments and viruses.”

Whereas the alphanumeric official names of ailments and their variants could also be complicated for the typical individual, they serve essential functions for specialists corresponding to microbiologists and virologists. Names of viruses are given by a gaggle of virologists and phylogeneticists that serve on the Worldwide Committee on Taxonomy of Viruses (ICTV).

Whereas there isn’t a common methodology for naming viruses, a typical method to classify a virus is by its antigens — elements that provoke an immune response and whose mutations are notably essential. For instance, as famous by Nationwide Geographic, Influenza A has two outstanding antigens, often called H (which stands for hemagglutinin) and N (which stands for neuraminidase). Each time these antigens mutate, they get assigned a brand new quantity. That is how probably the most notorious pandemic influenza subtype obtained its identify H1N1.

Within the current context, with the COVID-19 pandemic having precipitated devastation and disruption the world over, it is just pure that nomenclature related to it is going to get far more consideration. The WHO’s set of names introduced on Monday may assist making discussions in regards to the virus simpler.
