Case Fatality has some utility in the middle of a pandemic but one cannot use midpandemic or earlier CFR data to make a sweeping generalization about a disease’s overall mortality. Once the pandemic is over, you can do that but not until then. There are way too many variables built into midpandemic and earlier CFRs. It only serves as a snapshot in time but it frequently gets misused to make a statement like Covid has a .1% fatality rate”.
NYS is counting probables, repeat positives of the same patients, and asymptomatics as cases.
How can you possibly get a reliable case fatality rate or ratio using crap stats like those?
