I'm still convinced that SK's 1.74 percent is a good representative case fatality rate, especially in the absence of ventilator shortages. The outbreak there is has been ongoing for awhile, allowing most patients to continue through the course of disease. Ongoing new infection and fatalities are very low and positive tests are only occur in 2 percent of all tests. I guess we still don't technically know the "attack" rate. Maybe only a subset of the population will actually get infected. The positive test rates in many of the hard hit countries are too high so the CFR in those places seems inflated.
