Technique of naming pathogens has usually been controversial-Well being Information , Alenz
With quite a few variants of the novel coronavirus having emerged worldwide, individuals in all places have struggled to maintain observe of their complicated alphanumeric names
The World Well being Organisation on Monday introduced that COVID-19 variants are to be recognized 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 all places have struggled to maintain observe of their complicated alphanumeric names. The casual different in lots of circumstances has been to determine variants in accordance with the locations the place they had been first seen. Nevertheless, this technique has raised issues over its potential to result in stigma towards international locations 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 —
They won’t exchange current scientific names, however are aimed to assist in public dialogue of VOI/VOC

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 stories with the Union well being ministry stating that the UN’s high well being organ has not used the phrase “Indian” for this pressure in its paperwork.
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.
Below 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 equivalent to B.22.214.171.124 will nonetheless proceed for use in scientific circles, for the mutation info that their title conveys.
“Whereas they (lineage names) have their benefits, these scientific names will be troublesome to say and recall, and are liable to misreporting,” the WHO stated in an announcement.
“Consequently, individuals usually 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 stated.
The WHO has been making an attempt to provide you with simplified new nomenclature for the variants for a number of months.
The Greek alphabet accommodates 24 letters however there is no such thing as 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.
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 usually been fraught with controversy.
Traditionally, viruses have usually been related to the places from which they’re thought to have emerged equivalent to Ebola, which is known as after the Congolese river of the identical title.
However this may be damaging for the locations and infrequently inaccurate equivalent 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 techniques professional Chandrakant Lahariya as saying, “We all know that for lengthy, these ailments and viruses have been named after the town or locations the place they (are stated 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 known as ‘American Flu’. However as you recognize, persons are actually sensible, 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 common individual, they serve necessary functions for specialists equivalent 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 is no such thing as a common technique for naming viruses, a typical approach to classify a virus is by its antigens — parts that provoke an immune response and whose mutations are significantly necessary. For instance, as famous by Nationwide Geographic, Influenza A has two distinguished antigens, referred to as 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 received its title H1N1.
Within the current context, with the COVID-19 pandemic having induced devastation and disruption the world over, it is just pure that nomenclature related to it can get far more consideration. The WHO’s set of names introduced on Monday might assist making discussions concerning the virus simpler.
