Scientists also suggested that influenza and coronavirus “conflict” with each other, Larisa Popovich, director of the Institute for Health Economics at the Higher School of Economics, told RBC. “We started doing PCR tests, and it became clear that the flu was being replaced to some extent by the coronavirus. There have been suggestions in the scientific literature that these two species conflict. It is difficult to say how much they conflict, ”she said.
“I think we hardly have it [грипп] let’s forget, “Nikolai Malyshev thinks. “It’s not just that the flu and the coronavirus are in conflict, the point is that when there are two viruses, there is interference between them – they can both strengthen and weaken each other,” he added.

At the same time, in mid-January in 32 Russian regions were exceeded the thresholds for the incidence of ARVI, recalled the virologist, professor at Moscow State University, Doctor of Biological Sciences Alexei Agranovsky. He admitted that the prevention of coronavirus also helps against the influenza virus – masks, remote work and study. “After all, their distribution paths are the same,” he said. At the same time, there are parainfluenza viruses and adenoviruses that “spread by droplets, which is similar to the usual ways of spreading coronavirus and flu.” “And that’s why some have decreased, while others have appeared more – an interesting question,” said Agranovsky.
In the last, current season, “there really is no morbidity caused by influenza viruses,” said RBC, Candidate of Biological Sciences, Deputy Director for Research of the V.I. A.A. Smorodintsev ”of the Ministry of Health of Russia Daria Danilenko. She added that for more accurate statistics, the institute monitors the incidence of influenza by season, since it has a seasonality.
Only a few cases of influenza were laboratory confirmed, which is “a fraction of a percent of the total number of samples tested”. “A similar picture is observed in other countries of the world – both in Europe and in America, and in the countries of South America, Asia and America,” Danilenko said.
Among the reasons for the reduction in influenza cases, Danilenko called the introduction of restrictions due to the coronavirus in the spring of 2020, when “the number of influenza cases has sharply declined.” “Again, this has been observed in many countries of the Northern Hemisphere with similar measures. Using the example of Australia, we can say that restrictive measures affect the incidence of influenza – there was no epidemic there in the usual period of 2020, despite the fact that the COVID-19 epidemic was rather outbreaks in comparison with the scale of other countries, ”the scientist added.
At the same time, the Research Institute of Influenza recalled that the circulation of other seasonal diseases – rhinoviruses, adenoviruses, parainfluenza viruses and other seasonal ARVIs “is currently continuing”. “The flu can still come into circulation in the spring months, when the COVID-19 epidemic subsides, so you need to remember that compliance with restrictive measures and successful vaccination of the population against influenza in the fall will minimize this likelihood,” Danilenko said.
In mid-January at Rospotrebnadzor fixed exceeding the threshold of ARVI incidence in 32 Russian regions. Most of the viruses of non-influenza origin were found: parainfluenza, adenovirus, PC viruses, and other viruses. Rospotrebnadzor noted that in preparation for the season of infections against influenza and SARS, about 86 million people (59% of the population of Russia) were vaccinated.
Like January 14 told General Director of the Center. Gamalei Alexander Gunzburg, a combined vaccine against coronavirus and influenza may appear by 2022. According to him, her technology has already been worked out. Scientific research confirmedthat influenza vaccination reduces the risk of death in people with cardiovascular disease.
