Couple of things to note about COVID-19 are that we really do not know yet how widespread this is in the USA because we have barely tested for it yet. We are ramping up testing now, so the number of confirmed cases is likely to grow fast mainly because of the availability of the test.
Johns Hopkins put together a realtime map of the virus. If you are interested in looking at it here is a direct link to map:

Click on the number of cases on the left hand side (# of confirmed cases) and it will also tell you the number of recovered as well as the number of fatalities attributed to COVID-19. These numbers are expected to grow rapidly.
As mentioned above the scary thing about this virus is that we do not yet have a vaccine for it yet and its mortality rate seems higher than the flu, a virus that we also take pretty seriously with a large effort to inoculate our population annually.
Stay safe and practice good hygiene.
