Some strain mutations are adapted to mouse receptors and are incompatible with human receptors.
American researchers have found new evidence of the origin of the Omicron coronavirus strain from animals. This is according to a new study from the University of Minnesota School of Medicine, writes MedicalExpress.
It is noted that some strain mutations are adapted to mouse receptors and are incompatible with human receptors. This suggests that the virus may first be transmitted between other animal species, and then to humans.
In addition, these data are evolutionary traces left by the virus during its transmission from one animal species to another.
“Our detailed structural biology approach has successfully resolved these subtle but distinct evolutionary traces,” said one of the study’s authors, Dr. Fang Li.
He added that the results also indicate that animal surveillance may be important to prevent the emergence of new variants of COVID-19 in the future.
Recall that at the beginning of this year in Denmark, Omicron was the dominant strain of COVID, but its sub-variant has been identified, which may be more contagious.
Ukraine received 500,000 doses of the Omicron vaccine
