Sweden Says PCR Tests “Cannot Be Used To Determine Whether Someone Is Contagious”


The Facts: The Swedish Public Health agency has a notice on their website explaining how and why polymerase chain reaction (PCR) tests are not useful in determining if someone is infected with COVID or if someone can transmit it to others.

Reflect On: Why has this issue not been brought up within mainstream discussion? Why is health policy being decided by "cases", of which we don't know how many are infectious, using PCR tests?

According to the Swedish Public Health Agency, PCR technology cannot distinguish between viruses capable of infecting cells and viruses that have been neutralized in the immune system. As a result, these tests “cannot be used to determine whether someone is contagious or not.” They emphasize what many other experts in the field have been emphasizing during the entire pandemic, that,

“RNA from the virus can often be detected for weeks (sometimes months) after the illness but does not mean that you are still contagious. There are also several  scientific studies that suggest that the contagion of COVID-19 is greatest at the disease period.”

Even if RNA is detected at anytime, this does not mean you are infectious and capable of infecting others.
