A new variant of the virus has been discovered in the UK, and cases have occurred in 10 countries.The new variant virus is genomically identical to the B117 virus previously discovered in Kent, England. . .

A new variant of the virus has been discovered in the UK, and cases have occurred in 10 countries.The new variant virus is similar in genome to the B117 virus strain previously discovered in Kent, England, and has a disturbing set of mutations, namely the E484K mutation in the spike protein.The spike protein is located on the periphery of the virus and is considered to be the key for the virus to enter human cells.The variant viruses in South Africa and Brazil also have E484K mutations.

According to a report by the Central News Agency today, according to a study by the University of Edinburgh, a new variant of the virus has been discovered in the UK, and cases have occurred in 10 countries.

According to a study by the University of Edinburgh, a new variant of the COVID-2019 virus strain B1525 has been discovered in the United Kingdom. So far, 23 cases have been found in the United Kingdom. In addition, it has also been detected in 10 countries including Denmark, the United States, and Australia.According to the British "Guardian" (The
Guardian reported that a new variant of the 2019 coronavirus disease has been discovered in the UK, and there is a set of worrying mutations, which should be paid more attention during screening.

According to the paper, according to a study by the University of Edinburgh, 1525 cases of the new variant virus B23 have been found in the United Kingdom so far, and it has also been detected in viral gene sequencing in 10 countries including Denmark, the United States and Australia.It can be traced back to the virus strains that appeared in the UK and Nigeria in December last year.The research team said that the new variant virus is similar in genome to the B12 strain previously discovered in Kent, England, and there is a disturbing set of mutations, which is the E117K mutation in the spike protein.The spike protein is located on the periphery of the virus and is considered to be the key for the virus to enter human cells.The variant viruses in South Africa and Brazil both have E484K mutations.

According to Professor Clark of Reading University (Simon
Clarke) said that although it is not clear whether the mutation will change the probability of infection of the virus or the severity of the disease after infection, the E484K mutation in the South African variant virus causes the virus to develop a certain degree of resistance to some vaccines.Clark said: "We still don't know how widespread this (new) variant virus is, but if it spreads on a large scale, it can be predicted that any vaccination or previous vaccination will be discounted."

Clark said that the new variant virus B1525 should be listed as a target for enhanced screening. "I think until we have a better understanding of the variant virus, any virus with E484K mutation should be listed as a key target."

According to the report, the UK has just reached the “major milestone” of the first dose of vaccine for 1500 million people at the highest risk of infection, and is preparing to launch the next phase of the vaccination plan.
