What constitutes a "case"
40+ cycles of a test run over and over just to make sure it turns up positive?
Or test + symptoms?
Definitions are changing like FauXi's underwear.
Lies, Damned Lies, and Statistics.
The vast majority of the public, and a solid majority of those any any sort of position of authority,
are too poorly trained to actually sort things out-—
and while asking for strict definitions and following things through would likely allow for decent decision making that could be explained and defended to the masses, the shifting sands make that pretty impossible in the present climate.
Babel.
