A new subspecies of the “omicron” strain of SARS-CoV-2 found in the Chinese province of Jiangsu may enter Russia and cause a new wave of infections. This was reported to socialbites.ca by immunologist Vladmir Bolibok.
“There is a danger that the subspecies will be introduced and then spread with us,” he said. – The greatest concern arises from the emergence of new lines, types, subtypes – that is, mutations that can lead to somewhat bypassing immune protection in people who have been vaccinated and who were previously sick, as well as further transmission. And now the case registered in China is only a bit of a concern because because a new version has caused it, it means that it not only has the ability to reproduce inside a person, but also has the ability to be transmitted from person to person.
Bolibok added that the coronavirus, like many other viruses, has shown a great potential for mutation since the beginning of the pandemic, and that this potential has not yet been exhausted today. The mutations that give rise to new subtypes and variants affect the protein spikes of the virion required to attach to the cellular ACE2 receptor, and there are a large number of such mutations – so far it has not been possible to calculate them all. even variants with the help of computer models.
Previously, a new subspecies of the “omicron” strain of SARS-CoV-2 was discovered in China. The sample, which is unlike any of the known variants, was taken from a patient with moderate COVID-19 and it is not yet clear how dangerous it might be. More about this and other subspecies of “omycron” – in material “Gazet.Ru”.
