Research New Coronavirus mutations may greatly increase infectivity

CNN reported that Florida researchers believe that their experiments proved that the new coronavirus has produced genetic mutations, making human cells more susceptible to infection.

The report said that researchers said that whether this mutation will change the development of the epidemic requires further research; but at least one researcher who did not participate in the experiment said that it may have changed the development of the epidemic, and this may be enough to explain that the virus in the United States and Why are there so many cases in Latin America.

The report pointed out that researchers at the Scripps Research Institute in Florida said that virus mutations have an effect on spike proteins, which are a structure outside the virus that the virus uses to invade human cells. . If this finding is confirmed, it will be the first time that the virus mutation has a significant impact on the epidemic.

The report said that the World Health Organization (WHO) just pointed out this week that mutations discovered by the new coronavirus so far will not affect the efficacy of various vaccines currently under development. Last week, the World Health Organization said that the mutation did not make the virus easier to spread, nor did it cause more serious diseases.

The report pointed out that Hyeryun Choe, a virologist at the Scripps Research Center who conducted the research, and his colleagues conducted a series of experiments in the laboratory and found that the mutation called D614G would make the virus thorny. Increased shape proteins make these proteins more stable, which in turn makes it easier for viruses to invade human cells. Research New Coronavirus mutations may greatly increase infectivity

The report said that scientists have been free to share the viral gene sequence, which, like all other viruses, will often mutate. American scientist William Haseltine said: “The virus mutated sometime in mid-January, making the virus more infectious. This does not mean that the virus is more lethal, but the infectivity has increased about 10 times .” Research New Coronavirus mutations may greatly increase infectivity
