So, in summary, with regard to our current "casedemic", positive tests as they are counted today do not indicate a “case” of anything. They indicate that viral RNA was found in a nasal swab. It may be enough to make you sick, but according to the New York Times and their experts, probably won’t. And certainly not sufficient replication of the virus to make anyone else sick. But you will be sent home for ten days anyway, even if you never have a sniffle. And this is the number the media breathlessly reports... and is used to fearmonger mask mandates and lockdowns nationwide...
I think that may be overstating the case. My understanding is that the test does not look for the virus itself but for some molecules that are believed to be associated with the virus. That means it has no way of telling whether you have the virus now or had it some months ago.
Also, PCR is NOT a test. It just replicates molecules. Every extra ten cycles adds roughly a factor of a thousand to the replication factor so 30 cycles means 1000³ or a billion in round numbers. 40 cycles is a trillion.
The inventor of PCR, Kary Mullis, told us that PCR was not useful as a diagnostic - but we used it anyway.
Correct, they look for markers. Segments that are common across all coronaviruses and many human genomes.
