The new variant was discovered in Vietnam and according to the authorities, it is much more transmissible by air than the others and they also warned that it could be more aggressive. This new strain is a combination of english (B.1.1.7) and the India (B.1.617.2).
3,595 new cases of the new strain have been recorded in 33 cities and provinces, nearly half of the total cases reported by the country since the start of the pandemic, with 7,107 infections and 47 deaths.
This new Indian variant with mutations originally belonging to that of the UK It is very dangerous, warned the Minister of Health of Vietnam, Nguyen Thanh Long.
In addition, I explain that in a short time, we will know the genetic code of this variant.
The English variant is currently the most worrying of all, while the Indian variant is one of the most resistant to vaccines. Being a combination of the two, the variant of Vietnam it can be more resistant to vaccines, more contagious and, in turn, more aggressive towards those infected.
A study published in the British medical journal confirms that the variant of UK It can spread faster thanks to its 23 genetic code mutations, and I’ve found it doubly lethal: it has a 99% death rate. In addition, it is between 40% and 70% more transmissible than previously dominant circulating coronavirus variants.
Its ability to spread rapidly makes B.1.1.7 a threat to be taken seriously, said Robert Challen, a researcher at the University of Exeter at the time.
The World Health Organization (WHO) has classified the Indian variant as a global concern. Various studies have confirmed that the strain spreads more easily than other strains of SARS-CoV-2.
How the coronavirus mutates
A report in Nature explained that the variants are complicated, each consisting of a collection of mutations that have the potential ability to change the original version of SARS-CoV-2.
Viruses multiply by copying their genomes over and over again. But, like an old copier, these copies are not always perfect. Each of these imperfect copies is a variant, ”the scientists explained.
Experts explained that the imperfections of the mutation do not change the behavior of the virus and may even be less successful than the original version.
“However, and very rarely, mutations can change the virus in a very big way: it can become more infectious and able to bypass the immune system and even vaccines. The more the virus reproduces, the more likely it is to accumulate these rare mutations, causing it to spread faster between populations and become more resistant to the human immune systemargued the scientists.
In this sense, they explained that: When this happens, it is when specialists speak of a worrying variant, such as those detected in South Africa, England, Brazil and India“.
