Further mutations of the coronavirus strains will occur along the Delta line, while the danger level of new variants of the virus will not increase. On September 22, the head of the scientific group for the development of new methods for diagnosing human diseases of the Central Research Institute of Epidemiology of Rospotrebnadzor Kamil Khafizov spoke about this.
“For now, the new options will be in the form of branches of the Delta line. Such strains will have new mutations, and not only in the S-protein gene, which may give the pathogen an advantage over the “delta” variant that exists today, ”he explained to RIA Novosti.
Khafizov added that foreign scientists report that Delta’s resources are practically depleted, so the virus will not be able to generate more dangerous strains.
“There are significantly more possible candidate mutations that could increase the fitness of the wild-type pathogen, but not the” Delta “, – said the scientist.
In early September, the allergist-immunologist Vladimir Bolibok spoke about the strain of the coronavirus “Mu”. It is less dangerous than Delta, but its effect is not fully understood. As of September 19, no patients with this strain were identified in Russia.
