American scientists have discovered a mutation of the coronavirus, which increases the number of “spikes” in his “crown” and makes it more infectious than other strains. This is stated in the study representatives of the new York genome center and new York University, pretentiously Preprint of which is published on June 14 on the website BioRxiv.
As writes Reuters, the study may explain why outbreaks in some parts of the world do not lead to such consequences as, for example, in new York or Italy.
The authors note that the mutation D614G increases the number of “spikes” which the virus attaches itself to the human cells, in four or five times, causing SARS-CoV-2 is more infectious. In some cases, the virus is about eight times more effective connected with human cells than the coronavirus without such mutations.
Unknown at this time whether this feature is on the severity of coronavirus disease and the probability of death.
