Data notes
Negative test results reported in our API and CSVs are calculated by subtracting Confirmed cases from Total PCR tests (people).
On March 1, 2021, New Hampshire's Total PCR Tests (people) decreased by 563 without explanation. This in turn affected Negative PCR tests (people), which is calculated as Total PCR Tests (people) minus Confirmed cases.
On February 8, 2021, New Hampshire's Total antigen tests (specimens) decreased by 102 without explanation.
On January 10, 2021, New Hampshire’s Total antigen tests (specimens) increased by 41167 without explanation.

On December 26, 2020, we began capturing New Hampshire's "Antigen Positive" cases as Probable cases instead of Positive antigen tests (people) and revised its historical numbers so that Confirmed cases reflected only PCR positives. We also modified Negative (people or cases) to subtract these confirmed cases. Because negatives are calculated from lumped figures including antigen before November 20, negatives are artificially high on that day.
