Washington: Scientists in the US state of California have reported the discovery of an unknown mutation of the coronavirus, The New York Times writes.
Experts have discovered a new strain of COVID-19 while searching for samples of the British variant of the coronavirus. As a result, a Californian variety of infection was found.
Scientists suggest that the CAL.20C mutation appeared in the state itself back in July last year, but until November it did not manifest itself in any way.
Then the strain began to spread seriously and was found in more than half of the samples taken on January 13 by a laboratory in Los Angeles.
At the moment, there is no evidence that the mutation is more deadly compared to other variants of the coronavirus. It is also not reported how infectious the CAL.20C mutation is.
