Scientist explained the asymptomatic course of coronavirus
Xeberinvar.com - Reports That-The reason for the asymptomatic course of COVID-19 lies in the peculiarities of the immunity of individuals. This was told to RIA Novosti by the doctor of biological sciences, head of the laboratory of bionanotechnology, microbiology and virology of the Novosibirsk State University (NSU), corresponding member of the Russian Academy of Sciences Sergei Netesov .
What exactly caused this feature is still unknown. However, it allows people to carry the coronavirus with little or no symptoms. Netesov explained that asymptomatic carriers are the main distributors of COVID-19. However, some of them infect a large number of people, because they do not wear masks.
As an example, the scientist cited a case that occurred in the spring of 2020. Then one infected person came to the choral society, which included more than 50 people. Together they sang for two hours, and a few days later all members of the band became infected. According to Netesov, such people are called super-distributors.
Previously, associate professor of the Russian National Research Medical University named after V.I. N.I. Pirogova, Ivan Konovalov , an infectious disease specialist at the Diavax center , said that some people who have had coronavirus can remain infectious for a long time. As the expert explained, the immune system of these people is tolerant to the presence of the virus in the body. Most often, they are asymptomatic carriers and secrete an infection for a long time, infecting others.
