OREANDA-NEWS. The chief infectious disease specialist of the Russian Ministry of Health Vladimir Chulanov said that the likelihood of re-infection with the coronavirus exists, but such cases are extremely rare. Interfax reports.

Re-infection depends on the individual characteristics of the person's immune system. According to Chulanov, if a patient has a weakened immune system, his body can produce an insufficient amount of antibodies.
