Coronavirus may eventually mutate into a more severe infection, such dynamics is not excluded due to the existence of "deltacron" - a hybrid of COVID-19 strains "omicron" and "delta", the HEAD of the Center named after A.I. N.F. Gameley Alexander Gintsburg.
Deltacron demonstrates that the potential for variability of the COVID-19 virus is very large and is not limited to point mutations,” the academician explained.
Gunzburg emphasized that this hybrid strain itself is not dangerous and "may not have epidemiological potential." However, Russians should be vaccinated against coronavirus before the start of the new epidemiological season, he said.

In recent weeks, the number of new patients with coronavirus detected daily in Russia has been growing. Ten days ago, on August 11, more than 25.8 thousand new cases were detected, on August 20, the operational headquarters announced the detection of infection in more than 40 thousand Russians - for the first time since the end of March.
The WHO also notes the high level of distribution of the Omicron strain in Eastern Europe. The organization pointed out that overall in Europe the number of deaths is decreasing, but “very high levels of transmission of COVID-19, driven by BA.5 Omicron sublines, remain, which is of general concern.” At the same time, Rospotrebnadzor sees no reason to return restrictive measures.

The delta coronavirus strain was first described in India at the end of 2020 and has been dominant in most countries of the world for some time. However, last year it was rapidly being replaced by the more contagious omicron strain, first identified in South Africa. As a result, this variant of the infection, which is more contagious and causes in most cases a less severe course of the disease, has become dominant. In June, Rospotrebnadzor reported that the omicron strain accounts for almost 98.3% of all cases of coronavirus detected in Russia.
Scientists reported the discovery of the deltacron strain in mid-August, while the danger of the “Russian deltacron” has yet to be studied, American geneticist Dmitry Pruss pointed out to RBC. By August 10, doctors had identified six patients with deltacron in Russia. “Five samples for research were taken in St. Petersburg , one in Moscow,” Rospotrebnadzor said.
