According to the expert, the new Omicron sub-version already exists and has been found in around 10 Indian states, reported IANS.
An Israeli health expert said on Sunday that the coronavirus of the highly contagious Omicron lineage in India is a new sub-variant of BA.2.75, reported IANS. According to the expert, the new Omicron sub-variant already exists and has been detected in about 10 Indian states. This included 69 such cases from Delhi (1), Haryana (6), Himachal Pradesh (3), Jammu (1), Karnataka (10), and Madhya Pradesh (5), Maharashtra (27), Telangana (2), India. Uttar Pradesh (1), and West Bengal (13). On the other hand, the Indian Health Ministry is yet to officially confirm the detection of the sub-version in the country.
In a series of tweets, Dr. Shay Fleshon with the Central Virology Laboratory at Sheba Medical Center in Tel Hashomer said that 85 sequences from eight countries have so far been uploaded to NextStrain, an open-source platform for genomic data.
According to experts, apart from India, seven other countries have also reported the Omicron sub-variant. This includes Japan (1), Germany (2), the UK (6), Canada (2), the US (2), Australia (1), and New Zealand (2), according to NextStrain data.
“So far none of the broadcasts based on scenes outside India have been tracked,” Fleation wrote on Twitter.
Is the new BA.2.75 Omicron sub-variant dangerous?
Dr. Fleishon says it is too early to tell whether BA.2.75 will be the next major variant, however, the increase seen in these sub-versions “is at a level not seen in the second generation variants from other variants of concern”. Has been”. Additionally, according to the scientists, “BA.2.75 will have an antibody escape that is similar to BA.4/5 with respect to the existing vaccination.”
It was based on the Omicron lineage with mutations in the S1 segment of the spike protein and specifically in the part of the spike protein that the virus uses to attach to and gain entry to cells.
Furthermore, so far these second-generation variants have been found within a region only in a few cases. This is the first time the second generation version from Omicron has spread to multiple regions.

What other scientists say
Thomas Peacock, a scientist at Imperial College London, said on Twitter, that the sub-version is worth “keeping a close eye on”.
BA.2.75 was also flagged off by the Bloom Lab at the Fred Hutch Research Institute in the US.
The sub-version “is worth following, as it contains considerable antigenic alterations relative to its parent BA.2,” the institute stated in a tweet this week.
The lab identified two mutations, G446S and R493Q, as being crucial.
