Testing uncovers active infections. Testing also results in more false positives, according to the Journal of The American Medical Association – PCR tests are so sensitive they can pick up positive results for up to three months, well beyond infectiousness. It just can’t be said often enough.
Testing symptomless people is useless. People without symptoms are highly unlikely to be contagious.
The only statistics that are useful are hospitalizations and deaths.
Anything else is window dressing for despots.
