Hi, has anyone tried to compute the R_t over time on the county level?

Hi, has anyone tried to compute the R_t over time on the county level? rt.live has the calculations over the state level and I am trying to run their code for each county. So far I have the daily positive cases from US COVID-19 cases and deaths by state | USAFacts, but I also need the daily number of tests - does anyone know where I can get this? \

Have you seen the work by covidactnow.org? They have estimates for R_t for each county.

Lots of the data they are using comes from covidcountydata.org (disclaimer, I’m involved in the project). We have county level test data for about 50% of the US population. There’s lots of gaps in what is reported, but we’re collecting a lot of what is out there. If you have particular geographies that you’re interested in and see an official source for, please don’t hesitate to ping us.

This is really helpful, thanks!
