and @Howard
I would again urge reading the CEBM predicitions. https://www.cebm.net/oxford-covid-19/
The likelihood is for a lower true mortality rate (they call it IFR in the paper). What we see reported will continue- until well past we're out of this peak initial period- to be falsely inflate by reduced testing.
In terms of developments in other nations, especially those with less developed healthcare systems, I would suspect we cannot project our data across effectively- due to a very different age and comorbidity profile.Anectodally, I can suggest that the worse outcomes are related to pre-existing CV disease.
This does not necessarily bode well, as taking SSA as an example- the prevelance there is very high (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4820479/)
If Covid-19 goes unchecked throughout the world then even a conservative 1% mortality rate will see 78 million dead so it has the capacity for outstripping deaths from starvation (albeit for a short while).
