All over the world, with even hitherto sensible governments now jumping on the PCR/overreactlon bandwagon (Sweden and Japan)?

..and what do you suggest they use instead of PCR?

Its not perfect but its not utterly useless. The problem is how the data is interpreted and used.

So do you have a use for their PCR data?

Data can be used quite easily for a trend in viral trend and if combined with other methods can be used to give a useful indication of if an individual is infected.
...but we dont do it that way. Which is the problem.

I'm an octogenarian. I knew nothing of "Polymerase Chain Reaction" testing before this year. Why would I?

I have gathered, though, that

it is not intended to find infectious subjects
it has a variable "amplification rate" which can alter the results, and
it has a false positive rate (as you would expect)

Data, even from a bad test, if it is consistently "bad", might be useful, but to take absolute values from a mass testing project in the way that has been done, and ignore the caveats, without even exploring the operational false positive rate, seems unwise.

Having said that, even these tests, which must be considered, at best, unreliable, are showing a decline in positive results, which may or may not be significant.

Altogether though, wholly unsatisfactory.

It is hard to imagine that most of the world is following the same mantra.Quite by chance and hidden in the mass of articles on statistics of one kind of another, is Reinner Fuellmich, renowned German and USA lawyer.He explains in clear English exactly how this so-called pandemic came about. For you tube to take him down with 1.5million view must mean something, especially someone who has spent his career fighting and winning law suits based on FACTS, against the likes of Deutche Bank, VW diesel fraud and Kuhne and Nagel the largest shipping company in the world.He is preparing a class action case as part of the German Corona Investigative Committee against the main protagonists Dr.Drostner the virologist responsible for the PCR test,Mr.Weiler veterinarian and head of Robert Knoch Institute and Mr Tedros Adhanom,Head of WHO..
His detailed explanation can be found under 'Crimes against Humanity' on various sites which are ever-changing as giant tech companies attempt to silence these voices.
Only when people realise this is a PCR pandemic can the real fight begin.

Yes, but how many people look beyond the headlines, like yourself? That is the problem.
