Even with repeated interactions with patients with coronavirus, some people do not become infected, said Areg Totolyan, director of the St. Petersburg Research Institute of Epidemiology and Microbiology named after Pasteur.
At the same time, the reason for this phenomenon is still unclear, he said during a speech at the Healthy Life 2020 forum.
“We still cannot formulate what biomarkers of this resistance, but the fact that there is a certain group of people who do not get sick after repeated contact with patients, and not just with patients, but with patients who are virus-releasing, is really so,” – quoted him as “RIA Novosti” on Tuesday, October 27.
Totolyan noted that this fact cannot be explained by the use of personal protective equipment and the observance of precautions.
The expert also said that Russians are developing population immunity to coronavirus.
The doctor noted that in June-July, the level of population immunity above 20% was registered in seven regions of Russia. And in September, in 10 out of 20 regions, an increase in the immune layer was recorded by 1.5-2 times.
