Corona: How much danger is there from new strains found in Britain, D. Africa and Brazil? Learn more here …

London. While the outbreak of the global pandemic Coronavirus continues. So at the same time, the problem of people has increased more due to the new strain. Actually, these new strains of corona virus are more contagious than their original form. Scientists are constantly studying them and are guessing how dangerous they are. It is noteworthy that new strains of Corona have been seen in Britain, South Africa and Brazil, which have now spread to many countries from there. Let’s know about these new strains, how contagious and dangerous they are.

The new strain of Corona found in Britain is spread in most parts of Britain, in addition it has also spread to more than 50 countries of the world. At the same time, the new strain of virus found in South Africa has also been found in at least 20 other countries of the world, including Britain, while no specific information has been found about the Brazilian strain. According to experts, there have been considerable changes in spike proteins in the new strains of the virus found in Britain, South Africa and Brazil. Actually, it is that part of the virus that sticks to the cells of the human body. This is the reason that these strains become more active in infecting and spreading cells.

Strain found in Britain is more deadly
British Prime Minister Boris Johnson has said that there is some early evidence that the new strain of corona found in Britain may be more deadly and perhaps also with a higher mortality rate. Britain’s Chief Scientific Advisor Sir Patrick Valence said that the rate of death from the corona virus in the country is quite alarming and there is no possibility of reduction in it.How dangerous are the strains of South Africa and Brazil?

Experts believe that strains found in Britain are 70 per cent more infectious than older viruses, but far more changes have been observed in the spike protein of South African strains than in UK strains. At the same time, three important changes have been seen in the spike protein of Brazilian strain, due to which it also looks similar to South African strain. In a recent research, it has been found that the South African strain has been able to cheat not only antibodies but also the immune system, that is, it can also re-infect people who have been cured by corona.
