Doctor of Medical Sciences, virologist Anatoly Altstein told why a person can get sick with COVID-19 again, and how the disease will progress.
He spoke about this in an interview with the Zvezda TV channel.
“The immunity in this disease is quite peculiar and there are repeated cases of the disease, they are not very frequent. To say that this person can get sick again, but this has no such chance, is rather difficult until this question is definitely not clear. It is only clear that repeated cases are rare,”- said the specialist.
He noted that this can happen against the background of a gradually weakening immunity, if few memory cells have appeared in the human immune system after a previous illness.
“It is possible that in a repeated case of infection, a person receives a higher dose of the virus, and he“breaks through”the residual immunity. But in general it should be easier, because there are some remnants of immunity and they should be "mobilized". Therefore, most often it should be easier, but it is known that sometimes it is not easier,”said Altstein.
Earlier, an infectious disease specialist, virologist, doctor of medical sciences Nikolai Malyshev, in an interview with the NSN, commented on the situation with vaccination against COVID-19.
