And that the fatality rate (CFR) as explained in SWP's article was between 10% and 20%, not around 2,5% ;)It should be noted that the 1918 influenza pandemic had a much more deadly pattern in that it killed more healthy and younger people than older people. Very different to what we are seeing now, so predictions based on this are probably not relevant.
