It's absolutely critical to know the reported death rate, is a proportion of the HOSPITALIZED population. That is a smaller group than the confirmed infected population, which is drastically smaller than the unconfirmed infected population.
Estimates of the real infection base are 10-20 times more people than the confirmed infected numbers. So if you take the number of deaths as a known, you can simply divide it by the estimated total infected to get a far more realistic total mortality rate. This rate will spike if our hospitals actually hit capacity, which they haven't done globally just yet.
Almost 40% of the people that get this thing, don't even show symptoms... that only makes real tracking of this mess that much harder, when you combine this reality with the known terrible testing rates you get far more accurate numbers. Also, you can estimate based on South Korea, which has done a far better job testing, and isn't trying to lie to us like China did. Take either road, and the numbers I just put out show themselves. I didn't come up with this myself, it came straight from several medical journals.
But
@britechguy is completely correct, we have too little data to know. All we have are estimates based on scraps.
The only thing we really know, it's not the death rate that makes this thing so scary, it's the infection rate. The simple fact that everyone can get this all at once, because it's basically a common cold in that regard. Even if only 0.1% die, that's still a number measured in thousands at least when you're working with 40-70% of the total population getting it.
US Total Pop 327.2 million
40% of that is 139.88 million
0.1% of that is 327,200.
And yet, Johns Hopkins is expecting the US to lose only 97,000 when the dust clears at this time.
