England’s health council is investigating a new shoot of Omicron

The genus Omicron coronavirus, known as BA.2, is being investigated by a health agency in England for fear of more rapid spread of the original virus.

The UK Health Security Agency said it was selecting the Omicron shoot as a ‘different one being investigated’ because of the “increasing number of BA.2 systems known nationally and internationally”.

Preliminary studies indicate that a small variation of BA.2 may be due to an “increase in size” on Omicron’s original form, known as BA.1, according to UKHSA, which emphasized that there is “very little evidence early last year. “. In addition, BA.2 was not classified as ‘stressful species’ – a high risk for new species.

About 426 cases of Omicron shoots were pursued in the UK, with the first of these being found in early December. Only 0.26 percent of Covid-19 cases reported in the UK last week that ended January 26 were BA.2.

Worldwide, approximately 8,000 BA.2 consecutive genomes have been added to Gisaid’s global repository.

The shoot was first announced in the Philippines in early December just a few weeks after Omicron’s operation began, but it appears to have won over its sister in several stages. Denmark and India now have a maximum of BA.2.

“It is a type of virus that mutates and mutates, so we should expect to keep seeing new species as the epidemic continues,” said Dr Meera Chand, event director at UKHSA Covid-19.

He added: “At present there is not enough evidence to prove that BA.2 causes more serious diseases than Omicron BA.1, but the data is limited and UKHSA continues to investigate.”

When the slightest change first appeared, experts expressed concern that it could be difficult to follow than the original Omicron model. Because of the genetic quirk, the original Omicron gene could easily be distinguished from the Delta genus that was previously identified by PCR tests because it did not have one of the three coronavirus genes – the S. gene.

BA.2 contains the S gene, meaning that complete gene sequence is necessary to differentiate it from Delta. However, since Omicron is now a major brand, this will not be a problem.

Dr Tom Peacock, a virologist at Imperial College London who was one of the first scientists to raise the sound of the original Omicron, told FT he did not believe BA.2 was a “major cause for concern” but added that it was. “It’s definitely worth a look.”

Even a small nation can surpass the original Omicron or become more complex “it would not be so dramatic in hospitals and deaths in the UK because all figures could be frustrated by the lack of protection in BA.1”, he said.

Sajid Javid, the UK health secretary, stressed that due to the UK vaccine “the number of people most affected by Covid-19 is low”.

“We are learning to have the virus – and thanks to our world-leading diagnostic method we can quickly identify and monitor any genetic mutations in Covid-19,” he added.
