The doctor believes that in some cases, PCR tests are not accurate and show a false result of the presence of COVID-19.
“If a person thought that he was ill a year ago, and now he is even more seriously ill, with a high probability I would argue that then it was not a coronavirus, but an incorrectly positive PCR test. And this is a common situation. As a rule, a year of antibodies after diseases do not disappear, we see people who were sick 250, 300 days ago, the vast majority of antibodies remain. But even if they fall, the second course should be much easier, “- said Donskoy.
The medic reports that the chances of re-infection are negligible.
“There is a possibility of being infected a second time, but it is very, very low. Such cases are worthy of description and scientific research. If a person’s course is more severe, this proves the fact that the first infection was some other virus,” he said.
The doctor also recalled once again that the “British” strain of the coronavirus is much more infectious than its predecessor.
“The British strain is really an important factor, because by all indications it is more intensively transmitted and more infectious. Thus, people who until that time were protected by their immune system and their natural resistance begin to get sick. In addition, people are tired of self-isolation, no longer stand and begin to expand the circle of communication, unfortunately, this often leads to the fact that they catch this virus, “he said.
