hi Maheem new subscriber
no there arent good reasons
look at the DNA - there are good reason to think it came from a bat or a pangolin
if you want to see a leak of a pathogen from a lab watch - "Cordon" - the Dutch version is best
The 'percentage death rate' is meaningless unless you know what it's actually a percentage of.
yeah but no but it is used a stat world over and is easily understood - start off with a body count ( that is the easy bit)
it is not a rate there is no time element - case fatality ratio - and for reasons described it is always an overestimate - and that is its meaning - it gives you an upper bound
America has a case fatality ratio of around 10%
a useful paper on 3000 cases is
https://www.nejm.org/doi/full/10.1056/NEJMsa2011686
and the short answer is: the authors have no idea
we are still stuck on - latino, black and asian patients get more hospital admissions ( so more in the 20% death rate band) more admitted to ITU ( death rate goes up ) and ventilations ( up to 80% dead)
that high blood pressure, and diabetes is bad and are all present in gtr proportion in the high risk groups
and that is IT - as we were in Feb 2020 and no further forward
