Rospotrebnadzor reported on the dominance of stealth omicron in Russia

“No new strains have been identified in Russia lately.

Dominating now in the country is the BA.2 stealth omicron, which accounts for more than 90% of all infections, ”he said in a comment to RIA Novosti.

Omicron variants BA.4 and BA.5, which are most common in South Africa, are also of concern, he said.

Khafizov called the "stealth omicron" the most contagious variant of the coronavirus during the entire pandemic.

The head of the Department of Virology at the Faculty of Biology of Moscow State University, Olga Karpova, earlier in an interview with RT, urged to think about revaccination against the background of relevant statements.
