New cases are the total number of newly reported cases of Covid-19 on the Island as of the date specified. Only those cases that are reported by the Island boards of health are included.

Confirmed cases are the total number of positive laboratory-confirmed PCR tests administered since the pandemic began either at Martha's Vineyard Hospital, at TestMV, the high school drive-through site, or another site verified by the Island boards of health.

Probable cases are cases reported to the Island boards of health that have been diagnosed in one of the following ways: by a positive test for Covid-19 antibodies or by a physician's diagnosis based on symptoms.

Total cases are the cumulative number of confirmed and probable cases of Covid-19 on the Island since the pandemic began. Note that the number of active cases on the Island at any one time is a much lower number.

More details about Martha's Vineyard cases, including the number of tests performed and the age and gender of patients, are available on the Island Health Care website.
