What none of the talking heads seem to want to consider are "asymptomatic cases." Which seem to be EVERYWHERE!
And... The way that allegedly is supposed to work is "you catch the bug, and beat it like a rented red-headed mule..." And then you're theoretically good, right?
Except that it seems that there are umpteen different versions.
However... In the early isolated populations, a lot of people never even caught it to beat it - possibly they had had it before. Personally, I think we're seeing a wave of coronavirus summer colds. Which are enough like the Bad Nasty to test as... The "case" curve this year seems to be almost identical to last summer about this time.
