It is very dangerous to draw any conclusions from the number of cases in the US. They follow the number of tests that are done and those are limited by the test kits available.

I spoke with one doctor in upstate New York. She said that the local hospital, Albany Medical Center, was stopping community testing and going back to the old procedure of only testing people who met a narrow range of parameters. (Exposure, travel, etc.) Then she said, "So it looks like we'll start plateauing."

The rate of case growth will vary with the rate of testing.
