Russian Health Watchdog바카라 웹사이트Rospotrebnadzor confirmed detection of the more contagious Omicron subvariant BA.4 in Russia.바카라 웹사이트
According to Kamil Khafizov, the head of genome research at Rospotrebnadzor's Central Research Institute for Epidemiology, told reporters that two national labs had submitted the viral genome of the BA.4 sublineage to the VGARus database.
He also mentiomed that the concerned samples dated back to late May.
The scientist also added that the BA.2 subtype still accounted for 95% of all new cases in Russia.
"A number of studies published recently have revealed that variants, known as BA.4 and BA.5, are a little bit more transmissible that the early forms of Omicron," he said.
Previously, the global health watchdog World Health Organization바카라 웹사이트 (WHO) had predicted in바카라 웹사이트May that Omicron sublineages BA.4 and BA.5 were driving a surge of the disease in unvaccinated countries while BA.2 subvariant remains dominant in the world.
The BA.4 variant was first detected from a specimen collected on January 10, 2022 in South Africa. BA.4 shares many of the same mutations as the original Omicron variant, but have more in common with the BA.2 variant. It possesses a number of additional mutations, some of which could change their characteristics.
On May end, four cases of B.A. 4 variant and three cases of B.A. 5 variants of the Omicron sub-lineage of coronavirus were found in Maharashtra.바카라 웹사이트Their samples were taken between May 4 and 18. Two of them had travelled to South Africa and Belgium, while three had travelled to Kerala and Karnataka.
About BA.4 Omicron Subvariant
It has been reported that the BA.4 shares more similarity with the BA.2 variant of Omicron than the original variant.바카라 웹사이트The BA.4 Omicron subvariant carries an L452R mutation, which was also previously detected in the Delta variant. This particular mutation is responsible for바카라 웹사이트making바카라 웹사이트the virus more contagious by enhancing the virus라이브 바카라 ability to attach to human cells. The L452R mutation also plays a pivotal role in evading바카라 웹사이트destruction by immune cells .
Besides, the BA.4 subvariant is also known to possess바카라 웹사이트another mutation called an F486V바카라 웹사이트near the바카라 웹사이트spike protein's binding site바카라 웹사이트to human cells. This may also help them partially evade our immune response, according to studies.
