There are people who do not seem to have the disease, even without taking the proper precautionary measures.
Faced with this reality, the Russian academic Areg Totolián stated that, in fact, some individuals do not get sick from Covid-19, even after repeated contact with infected people.
However, the member of the Russian Academy of Sciences and director of the Pasteur Research Institute of Epidemiology and Microbiology in St. Petersburg pointed out that it is not yet known what the immunity of these people to the coronavirus is due to.
“We cannot yet determine what the biomarkers of this resistance are. However, it is true that there is a group of people who do not get sick despite repeated contact with patients, and not only with patients, but with patients who are actively releasing the virus “, said Totolián in the forum” Healthy Living 2020 “, carried out in Moscow.
The academic emphasized that, at the moment, it is known that such resistance to the virus in these people cannot be explained solely by compliance with all prevention rules, including the use of personal protective equipment.
However, many individuals can become ill more than once.
Covid-19 patients lose their immunity to the virus after a few months, said Nikita Lomakin, research leader for the Russian Sputnik V vaccine in older people.
“Almost all people who have had Covid-19 completely lose their humoral immunity in the next three to five months and have a high risk of reinfection,” says the doctor, although other infectologists warn that this does not always mean that people lose their immunity to the virus.
According to data compiled by Johns Hopkins University, more than 45.6 million people have been infected with the coronavirus in the world so far and almost 1.2 million individuals have died as a result of the disease.
The United States, India and Brazil are the countries that register the highest absolute number of deaths as a result of Covid-19.
