A 'new mutant' of the new corona with more than 30 mutations will be discovered, which is expected to be called a 'new mutant'

It is reported that a new strain of coronavirus has been found in South Africa. 2021 November 26, 'at a meeting of the WHO of the

mutant strain is a concern ' or ' mutant strain should be noted that this mutant strain, which is expected to be specified in' is a very, including the found mutations in the delta mutant Researchers are wary of the large number of mutations that can reduce the effectiveness of the vaccine and increase the risk of aggravation.

The journal Nature said on November 25, 'South African researchers are rushing to track down new variants of the new coronavirus. This variant is expanding rapidly in South Africa and is a delta variant. It has many mutations, including those found in South Africa. '

This mutant strain, called 'B.1.1.529' at the time of writing the article, was first discovered in Botswana in November, and has also been confirmed by travelers from South Africa to Hong Kong. In addition, in the genetic analysis conducted in Gauteng, which has the largest city in South Africa, Johannesburg, 100% of the 77 new coronavirus samples were 'B.1.1.529'.

The number of new infections per day in South Africa, which was 106 on November 1, has skyrocketed to 18,586 on November 23. As such, South Africa's Health Minister Joe Fahara commented, 'This mutant is a serious concern and may be responsible for the exponential increase in case reports.'

One of the major features of 'B.1.1.529' is that there are more than 30 mutations in the spike protein used by viral particles to inject genes into human cells. Since these mutations include mutations found in alpha mutant strains and delta mutant strains, they have acquired the high infectivity and ability to avoid antibodies possessed by past mutant strains. There is a risk.

'A group of WHO experts met on November 26 to call this variant a'variant of concern'or a'variant of concern',' said Turio de Oliveira of the University of KwaZul Natal, South Africa. If this variant is certified by WHO, it will be named '

Ν (new) variant' according to the Greek letter naming convention. '

At the time of writing, the extent of the impact of B.1.1.529 on areas other than South Africa is unknown, but Alice Katturakis, who is studying viral evolution at Oxford University in the United Kingdom, said, 'Delta mutations. In countries where strains are endemic, you should be aware of the signs of the B.1.1.529 epidemic. We wonder if this variant will compete with other variants and rage. You'll have to figure it out, 'he told Nature.

The stock market is sensitive to the emergence of new mutant strains. The Nikkei Stock Average fell 700 yen from the previous day on the 26th, and fell below the 29,000 yen mark for the first time in a month, showing a rough pattern reflecting the upset of investor sentiment.
