I started tracking data for Oklahoma by using the State Health Department web site. That’s okay but it is just a fixed point in time every day. It would be like trying to figure out what is happening in drag race by measuring the speed a hundred yards out of the start. The sites below track the spread of the virus in real time.
If you have your own credible sources of data let me know and I’ll consider adding it.
Johns Hopkins University might be the gold standard. Reportedly some government agencies use it.
1point3 acres has a great site focused on the US and Canada
Here’s a site bopping around on Facebook that seems legit. It says “Use at your own risk” so I am passing that info along as well.
Worldometer has a great site with lots of data and curves. Lots of ads as well but not too bad.
GitHub, somehow related to the New York Times is a great source of data if you want t o create your own visualizations. It’s kind of a nerdy site but worth checking out.
