The 'test, test, test' call from WHO specifically applies to just ''suspected cases'' and those who recently had contact with confirmed cases. WHO isn't calling for speculative testing.
I assume Prof Tobyjug is referring to a PCR test but as testing the entire nation for anything is a fantasy it doesn't matter much.
The Three-Body Problem
I don’t see some users posts, but since they’ve been quoted .........
I agree (in parts) with 2 contributors postings.
WHO says “test, test, test”, so more tests ARE key. That is part agreeing with one contributor.
I also agree with cjcregg. One has to understand the limitations of a test : (sensitivity, specificity and its positive and negative predictive values - which involves sensitivity / specificity AND prevalence!).
One also has to understand which test, to apply those limitations.
a) RNA NAAT? (Commonly called PCR, though PCR is a tradename, so ‘PCR’ is to ‘NAAT’ like ‘Hoover’ is to ‘vacuum cleaner’)
b) Antigen testing?
c) Antibody testing? (If so, IgM? IgG? Both??)
Knowing which test(s), their limitations, and thus what the result actually MEANS is more important than a blanket statement of “test everyone!”, (and repeatedly ??! ) .... especially as it allows prioritisation of who gets what test to maximise benefit, until “testing for all” is more than a pipe-dream .....
Would you repeat a positive IgG test? If so, in what circumstances??
Just out of interest, how long did it take you to formulate this conclusion? I'm not looking for a particularly accurate answer, just round it up to the nearest nano second.
How is this going to work then?
Where are the medical personnel and laboratory staff required to undertake this massive project going to come from? Now this is just a stab in the dark but I'd imagine they'd be quite busy at the moment.
Even South Korea, who are recognised as having one of the most aggressive testing policies have only managed to test 1% of their population. You clearly have no conception as to the scale of what you're proposing.
Even if it was possible to plan, organise and execute it would take years to achieve, by which time all the data would have been redundant and completely meaningless. I was tested last week and it took 2 days for the result, which by the time I received it was already out of date as I was then and now just as likely to be infected as I was when I took the test.
Think about it.
