Edgartown was listed as a high-risk community for Covid-19 spread by the state on Thursday, joining Tisbury in the red zone as new cases on the Island reached double digits for the second day in a row.

In a daily case update, health agents reported 10 new positive coronavirus tests Thursday, eight from Martha’s Vineyard Hospital and two from TestMV, the free testing site at the regional high school. The hospital is testing symptomatic patients and their close contacts for the virus, while TestMV is focused on asymptomatic testing.

There have now been 57 new cases reported on the Island since last Friday; about two-thirds were individuals who received positive coronavirus tests at the hospital.

The six Island boards of health release active case numbers on a weekly basis every Friday. Last Friday, the health boards reported 55 active cases on the Island. That number does not include the 57 cases reported since Friday evening.

In total, the Island has reported 240 positive coronavirus tests since the pandemic began in mid-March; 128 have come in the past two weeks, accounting for approximately half of all coronavirus cases on the Vineyard. An even larger percentage have occurred over the past month.

At a Zoom meeting with the Martha’s Vineyard Builders’ Association Thursday evening, health officials said that community spread was clearly occurring on the Island, and that a large number of cases were connected to the trades and construction industry. Edgartown health agent Matt Poole added that nine separate businesses in the trades have had an employee test positive for the virus, and that the vast majority of the recent case surge has been among year-round or long-term Island residents.

The age breakdown for positive cases on the Island is as follows: 37 cases under 20; 44 in their 20s; 54 in their 30s; 39 in their 40s; 36 in their 50s; 21 in their 60s; nine over 70. Of those cases, 114 are male and 126 are female.

On Thursday, the state also released a new weekly community-by-community case breakdown, with metrics rating each state community’s risk for coronavirus spread.

After reporting 31 cases in the past two weeks, and 57 total, Edgartown was listed as a high risk community by the state Department of Public Health for the first time Thursday. Tisbury was also included as a high-risk community for the second week in a row, after reporting 49 cases in the past 14 days. Tisbury has now had 77 positive cases in total.

Oak Bluffs, which was not listed last week, is listed as moderate risk, or yellow by the state after reporting 19 cases over the past two weeks. Oak Bluffs has reported 35 cases total.

Up-Island towns have all reported fewer than five cases during the relevant time frame, according to the state metrics.

Edgartown, Oak Bluffs and Tisbury all have 14-day per cent case positivity rates above four, with Tisbury the highest at 5.86 per cent.

Communities with less than 10,000 people are considered high risk if they report more than 25 cases over a two week period. According to state population estimates from the University of Massachusetts’ Donahue Institute, all Island communities are estimated to have fewer than 10,000 residents.

If communities are considered high risk for three weeks in a row, the community is required to revert back to an earlier phase of the governor’s reopening plan that further limits gathering rules and reduces capacity at gyms, performance venues, theaters and museums.

At the builders’ Zoom meeting on Thursday, Oak Bluffs health agent Meegan Lancaster said if state metrics considered the Island as a whole, the recent surge of cases would put it in the red zone for communities between 10,000 and 50,000 residents.

Statewide, case numbers continued to rise, with the DPH reporting 2,532 more cases on Thursday and 27 new deaths. The state has now reported more than 2,000 daily cases in six out of the last eight days. More than 192,000 people have tested positive across the state since the pandemic began, and 10,204 people have died.
