Coronavirus: Virologists evaluated the risk of complete disappearance of coronavirus


Coronavirus SARS-CoV-2, which caused the COVID-19 pandemic, is likely to disappear from the human population, virologists told RBC Trends. He certainly mutates, but it is difficult to predict now which directions and with what consequences. The most likely alternative is that the virus becomes less dangerous to humans, but together with this assumption, it is necessary to remember the serious threats that its spread in the world brings.

Doctor of Medical Sciences, virologist, professor at the National Research Center for Epidemiology and Microbiology named after N.F. Gamalei from Russia's Minister of Health Anatoly Altstein believes that the chances of the virus disappearing from the population are small, since SARS-CoV-2 is well adapted to the human body.

“I don't think he'll leave us: he adapted very well to humans, reproduces well in human cells and infects us easily. Why would he go anywhere? According to my forecast, in a year or two he will join a cohort of quite a few viruses that cause respiratory disease in our country, ”Altstein explained.

He added that usually the development of viruses goes in the direction of reducing their pathogenicity. “Evolutionary variants of viruses are selected that will infect humans well, infect very effectively, but not kill at the same time. This is a well-known pattern in general for many infectious diseases, ”the professor said. Altstein added that it is difficult to predict the future of the virus reliably. “But I still hope that it will not be so terribly varied in its antigenic properties. I think he should weaken his mood. It is unlikely that SARS-CoV-2 will be so peaceful, but it should not be so deadly anymore, ”concluded RBC's interlocutor.
