Coronavirus: Why everyone was wrong
So if we do a PCR corona test on an immune person, it is not a virus
that is detected, but a small shattered part of the viral genome. The
test comes back positive for as long as there are tiny shattered parts
of the virus left. Correct: Even if the infectious viruses are long
dead, a corona test can come back positive, because the PCR method
multiplies even a tiny fraction of the viral genetic material enough [to
be detected]. That’s exactly what happened, when there was the global
news, even shared by the WHO, that 200 Koreans who already went through
Covid-19 were infected a second time and that there was therefore
probably no immunity against this virus. The explanation of what really
happened and an apology came only later, when it was clear that the
immune Koreans were perfectly healthy and only had a short battle with
the virus. The crux was that the virus debris registered with the overly
sensitive test and therefore came back as “positive”. It is likely that a large number of the daily reported infection numbers are purely due to viral debris.
Which would mean all the 'X MANY CONFIRMED CASES!' could be just so much more bullshit.
