Just looking at the mortality rate of covid19 as an indication of its severity is flawed.
First up, Covid19 is a novel virus... it's new. Which means NOBODY has any immunity to it.
Based on conservative medical estimates, 10% of the infected will require hospitalisation (of which a smaller percentage will kick the bucket).
And this 10% of the total population will require medical resources and expertise. This is ON TOP of the existing hospital cases like heart attacks, seasonal flu, stabbings, PMD accidents, suicides, anxiety attacks etc etc
This 10% extra will overwhelm any medical infrastructure and cause more non-covid deaths
