Paris, Jan 04: Whereas the world continues to battle with Omicron variant of COVID-19, a brand new pressure, dubbed as ‘B. 1.640.2’ or ‘variant IHU’, has emerged in Southern France, and scientists have expressed concern over its excessive variety of mutations.
The brand new pressure has reportedly contaminated 12 sufferers in the identical space, and their exams have since revealed “an atypical mixture”.
The primary affected person had not too long ago returned from a tip to Cameroon, suggesting to specialists that it might have originated within the African nation, as reported by the Each day Categorical.
The pressure has been found by the researchers at The Méditerranée An infection College Hospital Institute (IHU) however will not be but below investigation by the World Well being Organisation (WHO).
US epidemiologist and well being economist Eric Feigl-Ding is one in all a rising variety of specialists exterior of France to boost the alarm over the brand new variant. Taking to Twitter, he wrote,”The mutations have triggered “Fourteen amino acid substitutions, and 9 amino acid deletions-which are positioned within the spike protein.”

”Whereas there are continuously new strains of the virus found, they not often turn into as outstanding as well-known variants equivalent to Delta and Omicron.What makes a variant extra well-known and harmful is its means to multiply due to the variety of mutations it has in relation to the unique virus, like Omicron,”he additional added.
Within the new preprint paper, dated December 29, scientists mentioned: “SARS-CoV-2 variants have turn into a significant virological, epidemiological and medical concern, significantly with regard to the danger of escape from vaccine-induced immunity.”
“14 amino acid substitutions, together with N501Y and E484K, and 9 deletions are positioned within the spike protein. This genotype sample led to create a brand new Pangolin lineage named B.1.640.2, which is a phylogenetic sister group to the previous B.1.640 lineage renamed B.1.640.1. Each lineages differ by 25 nucleotide substitutions and 33 deletions.”
“The mutation set and phylogenetic place of the genomes obtained right here point out based mostly on our earlier definition a brand new variant we named ‘IHU’. These knowledge are one other instance of the unpredictability of the emergence of SARS-CoV-2 variants, and of their introduction in a given geographical space from overseas,” it added.
