According to him, "people get sick again for several reasons."

“Coronavirus infection should not initially induce lifelong immunity.

This is not chickenpox, "RIA Novosti quotes Timakov.

He said that people get sick with diseases caused by coronaviruses every year, and every 3-4 years a disease caused by one pathogen is repeated.

Also, according to the infectious disease specialist, it is possible to get sick with coronavirus again with a high viral load - if a person is constantly in contact with sick people, due to the profession or certain circumstances.

In addition, re-infection is possible if the immune response after an illness has not fully formed or if immunity decreases due to the intake of certain drugs.

According to data as of February 6, 16,627 cases of coronavirus infection were detected in Russia per day.

The total number of reported cases of COVID-19 in the country has reached 3,951,233. 

Doctor of Medical Sciences Nikolai Kryuchkov, an immunologist, commented on the situation with the pandemic in an interview with FAN.
