You have very large, almost inflated case numbers, but (in the absence of symptoms) you don't know if those people are still spreading the virus or had it and are recovering.
That's because, if you are positive at a PCR test and without any symptom you may:
- Have not yet developed symptoms, and are infectious
- Have no symptoms, and are infectious
- Have cleared the virus, and are no longer infectious
Viral RNA can last in the throat for weeks in some cases (and it's not unique to this virus). That is why you can't detect the virus just with this test in absence of anything else (and the British Medical Journal wrote about this recently: advice to the doctors on how to interpret tests).
The New England Journal of Medicine argued for far more frequent antigen testing as a way to keep track of cases that are important to isolate, that is, the ones that are infectious[1].
My country did the same mistake (also using serological tests to assess positivity and infectiousness, a stupid mistake that just increased the backlog of tests) and of course tracing blew up.
