Sharjah24 – AFP: Covid-19 variants are to be known by letters of the Greek alphabet to avoid stigmatising nations where they were first detected, the World Health Organization announced Monday.
The new system applies to variants of concern -- the most troubling of which four are in circulation -- and the second-level variants of interest being tracked.
"They will not replace existing scientific names, but are aimed to help in public discussion," said Maria Van Kerkhove, the WHO's Covid-19 technical lead.
Under the new system, the variants of concern take on the following names: the hitherto so-called British variant B.1.1.7 becomes Alpha; the B.1.351 first discovered in South Africa becomes Beta, while the Brazilian P.1 becomes Gamma.
The so-called Indian variant B.1.617 is split into sub-lineages, of which the B.1.617.2 variant of concern becomes Delta.
The B.1.617.1 variant of interest is called Kappa.
Besides these names, there are two other scientific names in use for each mutation, while different geographic names have been used to describe the same variant.
For example, within Britain, what other countries have been referring to as the British variant is often called the Kent variant -- the county in southeast England where it was first discovered.
The lineage names such as B.1.1.7.2 will still continue to be used in scientific circles, for the mutation information that their name conveys.
