New York: March 2, 2020

On December 28, 2020, we cleared the history of New York's Confirmed Cases (PCR) field. We appear to have stored New York's cases count in our Confirmed Cases (PCR) field in addition to our Positive field because New York calls these cases "Total Tested Positive." However, we don't seem to have had sufficient evidence for this classification. "Positive" could have been antigen or antibody positive. Moreover, according to reporting by Kaiser Health News and The New York Times from the past few months, New York state includes antigen testing results in both its positive and total test counts.

Backfilling Total Test Encounters (PCR) and Positive Cases (PCR) from NY's dataset, and updating a few days at the beginning of the series for positives and negatives.
