U.S. researchers: New coronavirus may have mutated and infected more people

The virus, which has infected nearly 7 million people worldwide, is showing no signs of stopping and is likely to be one of the most contagious viruses ever found in humans. Why is the new crown virus so contagious? U.S. researchers have found that the new coronavirus may have mutated and become more susceptible to human transmission. Researchers at the Cripps Institute in Florida say existing studies have shown that the new coronavirus is likely to have “mutations” that make it more susceptible to human cells, according to U.S. media reports.

U.S. researchers: New coronavirus may have mutated and infected more people

The researchers note that the mutation could affect the virus’s “spike protein.” The “sting protein” is an external structure of the virus that allows the virus to enter the cell.

The researchers say the findings could explain why the new coronavirus in the United States and Latin America has infected millions of people.

As for the toxicity of the mutated virus, Hyeryun Choe, a virologist at the Scripps Institution, said: “In the cell culture system we use, viruses with this mutation are more contagious than viruses without mutations. “

However, the study is preliminary and is currently published on the pre-printed BioRxiv website and has not been subject to rigorous peer review.

Prior to this, domestic researchers have mentioned that the new coronavirus has mutated, but after peer review, the paper was corrected.
