A novel coronavirus mutant with 10 times higher infectivity is detected in infected people

The new is a variant of the coronavirus (SARS-CoV-2) '

D614G ' is, among the infected people 45 people by the beginning clusters from restaurant owners in the Malaysia, that it has been detected from at least three people Times of India Reports.

D614G was discovered in Italy around February 2020, and its presence was confirmed throughout the world. The difference with the new coronavirus confirmed in Wuhan in 2019 is in the 'spike protein' on the surface of the virus, and the sequence of the 614th amino acid is mutated from aspartic acid to glycine.

Research result that ``new coronavirus with strong infectivity'' born by mutation is pandemic in the world-GIGAZINE

A study by the Scripps University of Florida in June 2020 reported that mutated viruses were more likely to infect human cells than nonmutated viruses. The Scripps University research team commented that the mutation of the spike protein on the surface of the virus 'makes it easier for the virus to attach to cells and to infect it more efficiently.'

Bet Cober, a computational biologist and population geneticist, also claims that mutated viruses are more contagious when mutated and non-mutated viruses are present in the same space. Also, in a study published in July 2020, Mr. Cober said, 'D614G is a very dominant virus that increases the infectivity of the new coronavirus and has 10 times higher infectivity than the virus confirmed in Wuhan. '. On the other hand, Nathan D. Gourbeau, an associate professor of epidemiology at Yale University, pointed out to Cober's research that 'it is a study that suggests an increase in virus infectivity, but it is not proof.' did.

In addition, 'Most vaccines under development around the world are developed based on areas other than the D614G mutation, so they will not have a major impact on vaccine research,' the Times of India reports.
