The specialist, in an interview with Radio Russia, recalled that the level of IgM antibodies rises at the time of illness and falls after recovery, while the number of IgG antibodies that provide long-term protection against the virus, on the contrary, begins to grow.
Kulish said that an increase in IgM after a previous illness is a reason for seeking medical help.
“This means that somewhere in you this terrible virus is hanging, it is spreading.
And at this point I would rather not say anything ... you need to run to your doctor and figure out what to do, ”RIA Novosti quoted him as saying.
Earlier, NSN reported that the former chief sanitary doctor of Russia Gennady Onishchenko urged Russians to be vaccinated against coronavirus.
