We disabled the county-level testing data from Covid County Data for the following states due to discrepancies when compared to the PCR Test Specimen-based test positivity data from Centers for Medicare & Medicaid Services: "AL", "DE", "FL", "IN", "IA", "MD", "ND", "NE", "PA", "RI", "WI"
Possible issues with the CCD data:
Represents unique people tested instead of test specimens or similar. (I think this applies to AL, DE, FL, and maybe IN, PA, WI)
There was no "positive_tests_total" data and so we used "cases_total" as the numerator, which sometimes includes probable tests and therefore inflates the numerator. (possibly true for AL, IA, MD)
Note that the data is hard to compare directly since CMS provides a 14d test positivity percent rather than raw positive / total test numbers. So the comparison was somewhat subjective.
