The way it looks, were probably looking at death rates in America around 1.5-2.5% when this is all said and done (optimistically). But even at 1.5%, if 1 million get sick, you're still talking 15,000 deaths. And that's highly optimistic. In a worse (but still realistic) scenario, at a 2% death rate and 5 million cases, you're talking 100,000 deaths.

Getting back to normal too quickly makes the latter scenario far more likely... Or potentially worse.
