Professor of Virology, Chief Researcher of the Russian NIC named after Gamalei Anatoly Altestein commented on the hypothesis of Japanese colleagues on the possible self-destruction of the coronavirus delta-strain. He called it unlikely, but allowed a decrease in the contagious of this type of COVID, reports Expert.ru.
Previously, Japanese specialists put forward an assumption about the self-destruction of the virus due to a sharp decrease in the incidence in the country. They believe that due to mutations in the NSP14 protein, the virus has lost the ability to reproduce.
The scientists of the Russian Institute of Professional Education of the University of Sechenovsky noted that when entering the body, the polymerase DNA enzyme makes copies of nucleotides, but with some changes. This causes virus mutations and the emergence of its new varieties. These changes are insignificant, but when it becomes too much, the contagious of the virus decreases.
According to Alhestein, this can occur with any strain of the virus, including the “Delta”. However, the likelihood that he self-esteem, Mala. At the same time, the Russian expert added that physicians have no complete understanding of the attenuation mechanism of the epidemics of this scale.
