Coronavirus strains are now spreading in Russia, according to specialists from the Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing. As from September 2021, the Delta strain, including several lineages that have split from it, is the dominant one, Izvestia writes. The same variants are quickly spreading in the United Kingdom, Australia, Monaco, and other nations.
In terms of these subtypes’ characteristics, it is feasible to state that they are just as infectious as the Delta, but they are not any different when it comes to immunology.
Vaccines, according to medical experts, will continue to be successful as more comprehensive knowledge about the particular characteristics of new subtypes becomes known over time.
According to Anna Speranskaya, who is the head of genomics and post-genomic studies at the Central Research Institute of Epidemiology, the Delta variant is the main one with several branches “B.1.617.2.1, B.1.617.2.2, and B.1.617.2.3 (and so on until B.1.617.2.25).
According to Anna Speranskaya, who is the head of genomics and post-genomic studies at the Central Research Institute of Epidemiology, the Delta variant is the main one with several branches “B.1.617.2.1, B.1.617.2.2, and B.1.617.2.3 (and so on until B.1.617.2.25). It is also possible to come across several names for the same branches: AY.1, AY.2 (and so on until AY.25).
The branches that have expanded across Russia aggressively “occupy “other nations. According to the outbreak.info web site, the first AY.4 virus was discovered in September of last year, and as of today, there have been 242,600 samples registered, accounting for 8% of the total number of sequences. This variation is most common in the United Kingdom among European nations. “There’s a lot of it in Australia as well “,Speranskaya said.
Albert Rizvanov, director of Kazan Federal University’s Research Clinical Center for Precision and Regenerative Medicine, told the newspaper that there hasn’t been any data on the changes in characteristics between the AY.4 and AY.12 new lines and the original Delta strain. He also said that they are spreading faster than the Delta in certain nations, which may highlight their strength.
Pavel Volchkov, head of the genome engineering lab at the Moscow Institute of Physics and Technology, pointed out that there haven’t been any thorough investigations of the new strain yet, despite the fact that it and its sublines are more infectious and continue to spread globally.
According to the Central Research Institute of Epidemiology , the study and monitoring of the spread of SARS-CoV-2 variants is now being performed using data from the VGARus (Virus Genome Aggregator of Russia) site. This resource was registered in the month of June 2021. Currently, over a dozen Russian research institutes have uploaded SARS-CoV-2 sequences to the site. As of early September, the gateway contained approximately 25,000 sequences of whole genomes and S-protein gene fragments.
