American researchers looked at the latest genetic mutation in the Sars-Cov-2 coronavirus. This would be more transmissible than the previous one.
The Sars-Cov-2 coronavirus has evolved and this is not good news: according to researchers from the Los Alamos National Laboratory (in the United States), its “new form” is more transmissible and multiplies more easily than the version former.
Explanations. At the start of the Covid-19 epidemic in China, the Sars-Cov-2 coronavirus appeared in its first form; but arriving in Europe (in Italy, in France, in Spain …), the virus underwent genetic mutations to reach a new form – baptized D614G. Today, the “new generation” D614G coronavirus is the majority on the planet.
However, according to researchers from the Los Alamos National Laboratory (who published their work this Thursday, July 2 in the specialized journal Cell), the “new version” of the coronavirus would probably be more contagious than the previous one.
A “new” virus more transmissible but (probably) not more dangerous
“The virus seems to replicate better and may be more transmissible“commented Dr. Anthony Fauci, director of the National Institute of Allergies and Infectious Diseases in the United States. Indeed: according to American researchers, D614G would penetrate cells more easily than its” ancestor “. laboratory tests (cell cultures) confirmed this characteristic.
Is the “new” coronavirus more dangerous for health? At the moment, nothing is certain. “We do not yet know if a person is doing worse with him or not.“explained Dr. Fauci.
If the study authors believe that D614G could be associated with more important respiratory symptoms, it does not seem that “new coronavirus” is associated with a more severe Covid-19 disease. In short, research is progressing, and barrier gestures are more important today than ever …
