Recently, Russian scholars discovered 18 variants of the neo-coronavirus (CCA virus) in an immunocompromised woman, some of which are identical to the new mutant virus that appeared in the United Kingdom, and two that match the mutant neo-coronavirus carried by Danish mink.
The woman is 47 years old and has lymphoma, and in April 2020, she contracted the new coronavirus during a chemotherapy treatment, Russian newspaper Kommersant reported on 12 April. Since then, she has undergone regular nucleic acid testing, which remained positive until September 9.
It was reported that the mutant neo-coronavirus present in the woman’s body was partly the same as the mutant virus previously observed in immunocompromised patients and the same as the novel mutant virus emerging in the United Kingdom. In addition, the 2 mutant viruses also matched the mutant neocoronavirus carried by mink in Denmark.
Konstantin Krutovsky, a professor at the Department of Genomics and Bioinformatics of the Siberian Federal University, noted that this work confirms for the first time the fact that “the prolonged presence of a new coronavirus in an organism leads to the emergence of a large number of mutations. At the same time, he noted that it is too early to determine the rate of transmission of the “Russian” strain, since only this one case has appeared.
According to the latest data released by the Russian New Coronavirus Prevention website on the 12th, there were 22,934 new confirmed cases of New Coronavirus pneumonia in Russia, with a total of 3,448,203 confirmed cases, and 531 new deaths of New Coronavirus pneumonia, with a total of 62,804 deaths.
