Scientists at University College London in the UK found that none of the identified still of mutations in SARS-CoV-2 does not increase nor transmission nor its lethality. Article researchers, revealing the truth about the imaginary danger of coronavirus mutants published in the repository of preprints and bioRxiv.

Molecular biologists have analysed the viral genomes isolated from 15 thousand patients. All were identified 6822 mutations, with 273 mutations arose repeatedly. Scientists have identified 31 mutations, each of which arose at least ten times during the pandemic in different lines of viruses. Researchers have modeled the evolutionary tree, and looked, does that make certain mutations more frequent in this branch of the tree, that is, gives the advantage of SARS-CoV-2 to the reproduction, improving its ability to spread and infection.

The researchers found no evidence that any of the common mutations make the virus more dangerous. Instead, they found that some of the mutations are neutral (have no effect), and most changes in the genome are harmful to the virus.
