I've taken the case totals for NY, NY, CT (ie. because most of that is the NY Metro hot spot) and then all of the US to see how much the number of cases are growing. The only way these trends would be undercut is if testing has actually decreased over time, but we know that isn't the case. Even with the increased testing the rate of growth (ie. the exponential growth associated with epidemics) is slowing across all 5 groups shown above.

Two weeks ago, the daily growth rates were

NY - 50%
NJ - 20%
CT - 22%
US - 39%
Non-TriState - 33%

Yesterday, they were

NY - 10%
NJ - 15%
CT - 8%
US - 14%
Non-TriState - 16%

I'm not going to project what's going to happen the next 14 days, but I think the past 14 days can accurately be characterized as showing a significant reduction in the epidemic's growth rate.
