Two places you can go:
Here:
http://www.vdh.virginia.gov/coronavirus/
And here:
https://www.politico.com/interactives/2020/coronavirus-testing-by-state-chart-of-new-cases/
On the VDH site, you can click on each county to see totals. But you can see trend of reported cases.
On Politico site, you can see the growth trend in reported cases state by state by scrolling to the bottom of the page.
Thanks!
