Sweden Says PCR Tests: Cannot Be Used to Determine Whether Someone Is Contagious

Google translation:

The PCR technology used in tests to detect viruses cannot distinguish between viruses capable of infecting cells and viruses that have been neutralized by the immune system and therefore these tests cannot be used to determine whether someone is contagious or not. RNA from viruses can often be detected for weeks (sometimes months) after the illness but does not mean that you are still contagious.

I don't see how the european Covid-19 passport can survive this information.
