@Red Here's a Google headliner site with some numbers....
https://www.worldometers.info/coronavirus/
Just a bit of reasoning..... some "death" cases are people who died before any tests were done, but the remains on evaluation showed the diagnostic. Some "death" results may not even be based on an actual viral specific test, just a guess. We don't know how these numbers are checked or reported....
I suspect a lot of "cleared" results..... survivor data.... suffer from the same issues mathematically.
"confirmed" active cases may have the same "errors" as well.
10k deaths in 90k closed cases would figure 11% mortality, but no one..... not even the worst fearmongers I can find..... are saying THAT.
I see estimates of infective periods for carriers run out as long as 30d, and we just have not got good tests enough out there to get that measure.
But a 140k "active case" inventory is matched by a 7k "serious case figure". 5%, not 11%, on the "denominator" that is likely only 5% of the real denominator.... meaning over a million people exposed, mostly active spreaders right now.
So we've lost 10K, and have 7k in intensive care world-wide, as of today...… and probably 2 million unknowing/unknowable "carriers" out on the streets, infecting up to 3 people each within a few days' time.
The logic for restricted travel and social distance is that is how we can make these "carriers" dead-end infectives who transmit to no one. In 30 d they'll all be has-beens. mostly living "has-beens" who are no longer a danger, and no longer possible new cases.
Another just conversational observation here, is that the same guesses would mean that non-vulnerable antibody-competent stats only lag the disease by a month...., if no efforts to slow it down were made, and in that scenario we have only about 20k mortality in around 3M cases.....which would untreated, unmanagaed, result in a mortal rate of 0.15&
Of course, such an optimistic rate requires we don't overwhelm our health care infrastructure and careworkers like some initial outbreaks have done.....
