The Martha’s Vineyard boards of health reported one new confirmed case of Covid-19 Thursday, bringing the total number of cases on the Island to 69.

The new case is an individual who was tested at TestMV, the free testing site that has been up and running at the regional high school since June. Tisbury health agent Maura Valley said in an email Thursday that while two new cases were reported by TestMV, one was a re-test and will not be added to the total.

Positive cases to date on the Vineyard include 49 confirmed laboratory tests, and 20 probable cases, 17 from antibody testing and three symptomatically positive cases.

To date 20 males and 29 females have tested positive through PCR (laboratory) testing, while eight males and 12 females are listed as probable cases.

No new probable cases were reported Thursday.

Individuals can be tested more than once to confirm illness, or in certain situations, to be released from isolation, Ms. Valley said in her daily report from the six boards of health. This can account for a discrepancy between the number of positive individuals and the number of positive test results, she also said.

To date, 5,456 individuals have been tested at the TestMV site, while the hospital has tested a total of 2,522 individuals. The hospital only tests symptomatic patients and their close contacts, while TestMV is focused on testing people who are asymptomatic.

To schedule a free test with TestMV, call 1-877-336-9855. Online registration is also now available. The link to register and select an appointment time is available on the Island Health Care’s website, at health.questdiagnostics.com/IHC.

The town of Aquinnah is also offering self-administered saliva tests for Covid-19; to date 49 tests have been done with no positives.
