> We DO know that 10M people have had it, and 500K have died. That's 5%. We're still guessing everything else. No, the only thing we know is that 500K have died. At least 10M people have had it. 10M is the lower bound. The upper bound could be 30M+. How many cases are asymptomatic, or otherwise just untested/unreported? 5% is the upper bound for the mortality rate. Actual mortality rate is going to be significantly lower, perhaps even <1%.
