I’m not an epidemiologists (former research biochemist and high school chemistry teacher), but I was looking at the graphs and doing some of the math for the spread of the coronavirus in the U.S. and some specific states. The graph below is based upon conditions NOW:

I’m sorry it came out small, but the U.S. is on a trajectory of a doubling time for coronavirus cases of between every 2 to 3 days. I got this graph from the Financial Times. You should be able to click on the link to see it for yourself.

If the data is correct, the growth in coronavirus cases increases exponentially. This means that you can use an exponential equation to calculate the number of total coronavirus cases at a future time if you know the growth rate and have an initial number of cases.

**NOTE: I tried the trick that one of my commenters suggested to fix that unreadable graph. I couldn’t do it (not sure why), so I have place it in the the title image space.**
