New data released by the state Department of Public Health has designated all six of the Vineyard towns as low risk for the transmission of Covid-19, even as case numbers climb throughout the commonwealth and country.

The new state metrics, which are based on testing data collected through August 5, do not include three new cases reported on the Vineyard Tuesday and four new cases reported last week, illustrating the rapidly changing nature of the pandemic.

In his daily press briefing Tuesday, Gov. Charlie Baker said that the state would begin to closely monitor community-by-community data for the virus, hoping to isolate outbreaks and focus state resources on high risk towns that had shown widespread community transmission of Covid-19.

The data released Tuesday showed that each Vineyard town had reported fewer than five coronavirus cases in the past two weeks, placing them in the lowest incidence-level community group and among the lowest risk communities in the commonwealth.

“We’ve been seeing an uptick in Covid-19 patients in certain communities across Massachusetts,” the governor said in the press briefing. “The good news is that the vast majority of communities in Massachusetts are experiencing low Covid case numbers, and most are seeing trends moving in the right direction.”

Enhanced data from the state showed that in the time period from July 22 through August 5, only West Tisbury and Tisbury reported any positive tests (both reported one), putting positive testing rates on the Island at 0.1 per cent — among the lowest in the state.

Since the pandemic began, state data shows that West Tisbury and Tisbury have reported 11 cases, Edgartown has reported nine cases, Oak Bluffs has reported seven and both Chilmark and Aquinnah have reported fewer than five cases.

Of the four new cases last week, three were from the hospital and one from TestMV, the free testing site at the high school which is testing asymptomatic patients. The three new cases reported Tuesday were all from the TestMV site.

Overall, 318 communities in the commonwealth were designated as low risk, with levels of community transmission below five total cases in the past two weeks or below five cases per 100,000 residents, including all communities on the Cape and Islands, as well as the South Shore.

The cases per 100,000 residents metric has become widely accepted throughout the country as a way to gauge the level of coronavirus spread and prevalence in a community.

But the governor did note that 33 communities in the state showed moderate to high levels of community transmission, indicated by more than four cases per 100,000 residents over the past two weeks.

Four communities — Chelsea, Everett, Lynn and Revere — reported more than eight cases per 100,000 residents over the past two weeks. On Friday, the governor announced a new, targeted Covid enforcement and intervention team that will be responsible for ramping up enforcement for rules like face mask wearing statewide and coordinating intervention efforts at the local level in higher risk COVID-19 communities.

Governor Baker continued to urge caution at the press briefing Tuesday.

“The virus doesn’t care about boundaries,” he said.
