Russia Omicron sub variant BA.4 caseThe trend of getting new variants of Omicron in the world is not stopping. Now a sub-variant of the coronavirus strain Omicron BA.4 has been found in Russia as the most deadly new variant. It is highly contagious. Russia’s National Consumer Health Monitoring Organization (Rospotrebnadzor) has confirmed this.
Kamil Khafizov, head of genome research at the Central Research Institute for Epidemiology of the National Consumer Health Monitoring Organization (Rospotrebnadzor), explained that several recently published studies have shown that BA.4 and BA.5 differ. Types are more contagious than omicron. However, in 95% of cases reported in Russia, only subtypes of BA.2 have been found, he said. Two national labs have submitted the viral genomes of the BA.4 subline to the VGARus database to detect the most deadly subtype of the Omicron subvariant BA.4. Kamil Khafizov, head of genome research, said the samples were taken last May.
Learn the BA.4 Omicron sub variants.
It has been found that the BA.4 variant is more similar to the BA.2 variant than the original variant of the Omicron. The BA.4 Omicron sub variant has the L452R mutation, which was also found in the earlier Delta variant. Such specific mutations make the virus more contagious and increase its ability to invade human cells. L452R mutation plays an important role in protecting against damage by immune cells. In addition, the BA.4 sub variant has another mutation called F486V near the binding site of spike proteins in human cells. According to studies, because of this, all of these species also help to partially avoid our immune response.
The World Health Organization also warned.
The World Health Organization (WHO) warned in May that omecron subdivisions BA.4 and BA.5 were increasing the incidence of the disease in non-vaccinated countries, although BA.2 subtypes are causing the disease worldwide. Have been Are playing an important role. BA.4 was first detected in a sample collected in South Africa on January 10, 2022. Its mutation was found to be similar to the original variant of the Omicron variant, but it is similar to the BA.2 variant. Last May alone, four cases of BA4 variants and three cases of BA5 variants were found in Maharashtra.
