That chart is entirely plausible.
We should peak about mid-April, which is when everyone, and I mean everyone will be freaking out.
300,000 confirmed US cases is not beyond reason.
More than 100 deaths were added to the US tally, after I posted the chart earlier today (775 total). Numbers of dead are doubling every three days.
There are 21 days until tax day. If this doesn't slow, the death toll will double 7 times by then. We're looking at maybe 100,000 dead by the middle of next month, April 15, at the peak - according to JPM's analysts - chart source.
That's three times the flu. That many more could die on the other side of the peak. That's a possible 200,000 dead, if we don't find better cures, before the Corona virus burns itself out in the US alone.
