It's all about the location of the virus in the body Sergei Netesov, virologist and doctor of biological sciences, spoke about the right way to confirm full recovery from COVID-19. Discuss
According to Netesov, a one-time negative PCR test cannot be considered a guarantee of recovery from coronavirus.
The fact is that a PCR sample taken from the nasopharynx determines the presence of a virus in the nasopharynx. From there, as you know, the virus leaves quite quickly: it can be in the lungs, in the blood, in the intestines

In his opinion, PCR should be taken twice with an interval of about three days … And when the PCR in the nasopharynx finally becomes negative, you can check the PCR in the blood. This will be an additional guarantee that there is no coronavirus in the body.
At the end, Netesov warned that it is important not to forget about the risk of re-infection. According to him, vaccination can reduce the likelihood of illness and prevent severe COVID-19.
