COVID-19 New York - New Cases by Day

I created this page because I noticed two things on Sunday, 22 March 2020:

  • New York City published an update on case numbers for COVID-19 yesterday which had conveniently included a sub-series in a chart showing “number of new cases” on each day, and I saw that we passed the peak of a bell curve for that number on Thursday the 19th. That seemed like good news to me.
  • This morning the “new cases” figure was missing from that chart.

I'm not sure why they took that figure away, but as long as “total cases” only goes up, showing all known active, recovered, and deceased cases put together, then we can still derive “new cases” for each reporting day.

I found a good table of New York State total cases and delta each day in Wikipedia so I made a chart.

I'll try to keep this page updated every day for a while. If old numbers change on future days, watch the change log for comments.

Note, “new cases” jumped up again Sunday. Second wave already here? First wave not done? I have no further comment. Don't draw conclusions from any of this unless you know what you're doing!

2020-03-22 22:08: Initial release. Pulled data from 2020 coronavirus pandemic in New York (state) on Wikipedia at 2020-03-22 15:35 local time.

2020-03-23 16:31: Same source

2020-03-24 21:19: Added yesterday and today from Wikipedia; the figures don’t seem to be updated after they’re added for a day during that day. New Cases gone from Wikipedia list; now in my data it’s derived from the delta between two days.
