"Last week the first H3N2 flu virus was detected, the case disease brought to Russia from Egypt. So far, there are no other flu viruses in Russia. Therefore, we have time to work thoroughly on a plan of action," the press service of Rospotrebnadzor quoted Popova as saying on Saturday.

When speaking about the current epidemic situation, Popova noted that the country was on the eve of a new stage of the morbidity rise, through the situation for all respiratory infections circulating in Russia at the moment remained quite stable.

As the reports noted, influenza activity from October 2021 to May 2022 was significantly higher than in the previous season, but lower than the pre-pandemic period. "At the same time, the past season was characterized by the predominance of influenza A viruses, while the proportion of influenza B viruses remained small. The board stated that COVID-19 entered the circulation of the group of respiratory infections, disturbing the seasonality of the epidemic process of influenza and acute respiratory viral infections," the report said.
