A team of researchers found a few small pieces of the genetic material for SARS-CoV-2 in the genetic material of human cells. This may explain false positives.
The collection states in the US National Academy of Sciences (“PNAS”) procedures that there is no risk from the genetic material. These fragments cannot lead to complete viral particles nor can they lead to a renewed infection, writes researchers working with Rudolf Janisch of the Whitehead Biomedical Research Institute in Cambridge (Massachusetts, USA). This finding could be a possible explanation for the fact that some people have tested positive for SARS-CoV-2 on a polymerase chain reaction (PCR) test long after being infected with the virus.
The results of the study were supported by a study published in the journal PLOS ONE: A group led by Ethan Beltan at the University of Utah in Salt Lake City tested patients who were again positive for a PCR test 60 days or more after contracting the Coronavirus. Virus test test. In about 90 percent of cases, there was no SARS-CoV-2 infection despite a positive PCR test result, so there was no renewed infection.
