Mike . Does it need explanation?
The reality is covid was here long before the first cases were official. The symptom checkers were way oversimplified.
We were then told not to report it unless desperate because of perennially claimed “ overstretched” medical resources. So nobody knows how many cases are happening outside official channels.
This is true everywhere. When we had it in Portugal we were told not to report it, when Portugal had only 100 cases I’m official channels, we seemed to know half of them! and their symptom checker was no better than here.
So there is official world and parallel world everywhere. Italian statistics agency was saying the ultimate view of current death toll could be double the amount already claimed. No idea where they think the difference is.
I also wonder how many are exposed who are disposed not to get it, not just those who have it but are assymptomatic.
It will be years if ever before a true picture evolves,
