The fact about covid-19 need to understand "exponential thought" and not linear comparison.

It's as if you would compare Facebook-very-early-days trafic with Yahoo, when facebook was still a baby, and conclude: "facebook will fail, yahoo rules, google will fall behind" just because "hey last year facebook had 1000 visitors, who cares that it grows to 30 000 in a month, it's still less than 300 millions".

Exponential growth is something we practice so well in startups, in IT. This means we start noticing once facebook has 1 million, or 30 million, before it gets to 3 billion.

Now, speaking about required investigation, some flu deaths are actually covid19-claimable. But we don't know how many.

What we do know is that you should check hospital saturation "peaks" by disease. (peaks being the way it can concentrate and draw hospital occupation).

You will understand that covid overwhelms hospitals (by much more if nothing is done, meaning a non-negligible-at-all part of the whole population) and this triggers other related deaths which can actually increase the other deaths by XX % (+100 % being at least a strong candidate) and create new deaths causes, from usually mild situations, by lack of access to doctors and hospitals. And that's "if" medical staff survives a year-long covid-19, with hospitals overwhelmed by several thousand percents, or medical staff dying from it or being at least exhausted.

Still good to investigate and share information.
That's the reason why I shared these views!
