British researchers discover new strain of Covid-19 called G614

According to experts, this new strain is more infectious, although the severity of the disease does not increase with this mutation.

Researchers from the University of Sheffield (England) together with researchers from Duke University (United States), have discovered that a strain of covid-19 has mutated, having a higher infectious load without increasing the severity of the disease.

The new strain allows further spread of the virus

The mentioned strain is called G614, detected in the S protein (Spike) of the virus and is the one in charge of infecting the cells. According to experts, the virus, in its eagerness to survive, has mutated to prevent the host from dying and thus being able to spread.

In the study published by Cell journal, Professor Thusshan de Silva (University of Sheffield) explained that this new variant has a higher viral load lodged in the upper part of the respiratory tract, which ultimately allows the infection to be more severe.
However, he added that "fortunately, this does not seem to imply a more serious illness."

Another researcher in the study, biologist Bette Korber, said that "the GISAID project has allowed us to identify a variant that has become the dominant one."

The GISAID project has a total of 58,000 samples of the virus from all over the world, thus allowing a comprehensive study of the behavior of the virus in hosts with different environments.

This study has managed to release very important and key information about this virus that has already spread to more than 10 million people in the world and has killed more than half a million, making this project one of the most challenging in more than a century of human history.
