We dont know whether this new coronavirus strain is associated with a more severe condition in the infected person, he said. The virus seems to replicate better, perhaps more transmissible, but it is still in the stage of trying to confirm that.
They found that the new coronavirus variant, known as d614g, had small but powerful changes in the spike protein on the surface of the virus.
According to the report, in April this year, scientists published their paper for the first time on the biological paper archives of medical preprint website, which received 200000 hits, a record.
But the paper was initially criticized because scientists did not prove that the variation itself was the dominant cause, and that it might also benefit from other factors or contingencies.
They analyzed data on 999 British patients hospitalized for new coronavirus infection. They observed that patients with the new coronavirus variant had more virus particles in their bodies, but that did not change the severity of their condition.
Erica olman Safire conducted one of the experiments at the raoya Institute of allergy and immunology. It seems likely to be a more adaptable virus, she said
Nathan Gruber, a virologist at Yale School of public health, said the spread of the variant means that it is now a popular strain, whether by natural selection or by accident.. Gruber was not involved in the study.
