Epidemics of COVID-19 are occuring at different times across the United States so it is important to compare the spread of an epidemic in a given state with the appropriate stage in other countries. The following figures show the cumulative number of cases in a state by number of days since the 100th case, number of days since the 1st case, and by calendar date, respectively.

Hover over points to get additional information and drag over areas to zoom in. Double click a state abbreviation in the legend to isolate that curve and single click on a country or region in the legend to turn on or off a single curve.

For example:

Try double clicking the abbreviation for your home state on the right (I chose the GA).

Then we can compare to some well known state outbreaks: click once on the abbreviation NY (for New York), CA (for California), and WA (for Washington).

How does your home state’s outbreak compare to these more mature trajectories?

Note that differences in testing rates by country have very large effects on these numbers.
