In the United States, as of the time of this posting, 564,000 people have died to COVID, and we've had 31,400,000 cases, which puts the case fatality rate at 1.8%.
Yes, case fatality rate is 1.8% but infection fatality rate is quite a bit below 0.5% (the exact number is unknown since no one in the US is doing random testing properly). Bubonic plague infection fatality rate was 50-70%, so over 100x larger.
Also, it's quite suspicious that Japan has the highest IFR in the world, with the gap over the average much larger than can be explained by population age. Especially strange since Japan has some of the best medical systems in the world, and has not (yet) exceeded the capacity of its hospital system.
