"WHO reminds IVD users that disease prevalence alters the predictive value of test results; as disease prevalence decreases, the risk of false positive increases (2). This means that the probability that a person who has a positive result (SARS-CoV-2 detected) is truly infected with SARS-CoV-2 decreases as prevalence decreases, irrespective of the claimed specificity."
That's such idiotic double speak, worthy of 1984. Basically, that's saying... the test does nothing, just, if there's more symptoms going around there's a higher chance someone is sick, if there's fewer symptoms going around, there's less chance of them being sick. That's so stupid, and indicates the test does next to nothing!!
Hmm.... I certainly didn't read it that way. Prevalence in that context, I'm not sure if it makes sense? But highlighting the last part, 'claimed specificity', doesn't that also negate the overall efficacy of the test anyway?
That says nothing of the sort. It says PCR results must be carefully looked at.

I read prevalence to mean symptoms in an individual, not prevalence of covid in a community

Your quote has nothing to do with asymptomatic cases or your title, it has to do with the prevalence of a virus in a PCR procedure.
Now that DJT is gone.
