Interpretation caveats

Things that may differ from how other sources define a similar measure. If you're combining this dataset with another, read these first.

hospitalizedIncrease — Many states never reported daily new hospitalisations — column is NaN-heavy. Prefer NHSN HRD's totalconfc19newadm for analysis spanning 2020-08+.
totalTestResults — PCR / antigen mix differs by state and shifted over time. Don't compare raw test counts across states.
