Covid-19: the new form of the virus is even more contagious

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 former version.

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.

“It seems that the virus replicates better and can 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 penetrates cells more easily than its “ancestor”. Laboratory tests (cell cultures) have confirmed this characteristic.

Is the “new” coronavirus more dangerous for health? Now, nothing is certain. We do not yet know whether a person will do worse with it or not, according to 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 …
