I was waiting with bated breath for the CDC update on cases of COVID-19 in the U.S. by date of onset. To my eyes this looks like absolutely wonderful news - that it means that the exponential growth of the virus has been "flattened" - but I'm still afraid I may be misinterpreting what I see. It bothers me that the headline for the graph hasn't changed. But it APPEARS that the number of new cases stopped increasing after 3/3. Am I missing something?
Top: before noon on 3/16, bottom: after noon on 3/16. Data from https://www.cdc.gov/coronavirus/2019-ncov/cases-in-us.html
Note: In today's update (the first in three days) the CDC page shows the number of cases with onset on 3/4 to be 159, and 3/9 is 307. This doubled in five days rather than every two or three as other numbers would suggest, but given the dramatic changes in this curve, and their overall direction, I think the top answer below has been vindicated.
