A new subvariant of the delta variant of the corona virus that is spreading prominently around the world has attracted the attention of scientists. Its cases are increasing in many countries including England. This subvariant is being known as AY.4.2 and the data related to it is yet to come out. Its cases were first reported in England in July this year and now in these Seeing an increase.info
How is a new variant of the virus formed?
The SARS-CoV2 virus is behind the spread of the corona epidemic. Changes in the DNA of a virus are called mutations. When there are more mutations, the virus takes a new form, which is called a new variant. There are many reasons for the emergence of new strains of the virus, one of which is the continuous spread of the virus. gives. In such a situation, the possibility of variants increases as the patient increases. Corona Crisis
Increasing cases related to AY.4.2
A222V and Y145H are two major mutations in the spike protein of the AY.4.2 subvariant. On 15 October, the England Department of Health reported that cases associated with AY.4.2 were increasing and confirmed in 6 percent of the samples sequenced. Let us tell you that it is common to have mutations in the virus and most of the times these mutations are not dangerous. Viruses keep changing their form in a few weeks or months.Corona virus
Where are the cases of AY.4.2 being registered?
So far, most cases of AY.4.2 have been reported in England, but some cases have been registered in other countries including Russia, America and Israel. Of all the samples confirmed after genome sequencing, 96 percent are related to England. A few cases have been reported in Russia and it has been confirmed in an 11-year-old child who returned from abroad in Israel. No case has come till now.
Do we need to be worried?
Scientists say that AY.4.2 is more contagious than the delta variant, but so far it has not shown any signs that need to be worried. A Russian scientist said that it is more contagious than delta and later It can be replaced, but this process will be slow and the vaccine is also effective against it. Also, the data related to this is awaited, on the basis of which something can be said. Delta subvariant
Why is this subvariant getting special attention?
Experts say that the Delta variant has remained the dominant variant for the last almost six months. Due to this it was understood that the changes in the virus had reached its peak and new variants would not be seen in it. However, the new sub-variants have alerted the scientists. He says that there is a need to keep a special watch on it so that it can be controlled as soon as possible.
What is the status of infection worldwide?
Johns Hopkins University According to the report, so far around 24.25 million people have been infected with the corona virus worldwide, while 49.30 lakh people have died.
