The data sources I’ve used so far (sorry just realized I cannot post links to all the resources below since I’m a new user):
- Center for Systems Science and Engineering at Johns Hopkins University (been using this data set since late January)
- The COVID Tracking Project (for state-level testing data)
- Wikipedia article on testing (for country-level testing data)
- Various Department of Health websites (such as the Colorado Google Doc you linked to)
Shameless plug: I created this dashboard using my company’s product to track this data. I live in New York and have been tracking county-level data closely in this part of the dashboard (still WIP).
