So these guys look at 162.547 PCR tests done in Münster in 2020 (wks 10-49), finding that over half of positive tests have Ct values above 25, meaning these are post-infectious recovered people. Disease statistics are meaningless propaganda.https://www.journalofinfection.com/article/S0163-4453(21)00265-6/fulltext …
Here's the subset of positive tests for which we also have clinical data, plotted against Ct. Blue = symptomless; red = symptoms They're testing in the range of Ct= 33-36, i.e., precisely where you start to have as many symptomless non-infectious positives, as infectious onespic.twitter.com/OOkDeDTXlZ
And this. After some summer 2020 experimentation with testing asymptomatics, Germany went back to testing mainly symptomatic people in the fall, which gets you a higher % positive and *moar overall cases*pic.twitter.com/BINEfBZQW7
German lab capacity is probably more or less tapped out, remember, but they need positives for their scary graphs. So despite all theories that AsYMptoMAticS driVE thE PanDEmiC, they reverted in the fall to mostly symptomatic testing in order to get the richest harvest.
People w/symptoms are already staying home, remember. The added utility of testing them is very unclear But you need every last positive result you can get, so you test them mainly, and you test at high Ct thresholds to catch as many old no-longer-relevant infections as possible
Also, supposedly mass testing is for enabling contact tracers to track down all the disease bearers. Why, then, would you want to flood their docket with a lot of old recovered cases? Because positive cases are politically useful, and contact tracing is bullshit.
I am a biologist and used to go qPCR every day 35-40 is a range in which even your water negative control can amplify. It is a technical certainty that you will have false positives with this scheme.
You saw this when they ramped up asymptomatic testing massively in Aug 2020, and cases started to tick up in a more or less linear relationship to the tests being performed.
Another thing that isn't mentioned in the paper, are the reactions done with replicates? We would always run every qPCR reaction in double or triplicate. If the SD was too high the result was rejected.
The volume is almost certainly too high to permit controls like this. They automate as much of the process as possible (picrelated, what they have in Münster) and minimise staff interactions, & still most of the labs seem to be at capacity limits all the time.pic.twitter.com/DoQpuKn5ab
