Nantucket has experienced a spike in COVID-19 cases and is seeing “community spread” among tradespeople working in construction, landscaping, and cleaning who are sharing transportation to workplaces, officials from the town and Nantucket Cottage Hospital said Friday.

Seven new cases of the coronavirus were reported Wednesday, and another seven were reported Thursday, for a total of 77 cases in the town, according to a statement Friday from Select Board Chairwoman Dawn Hill Holdgate.

“These are the highest number of cases in a short period of time that we have so far seen in Nantucket,” Holdgate said.

Of those 14 new cases, a dozen were among Nantucket residents, and most of those residents worked in construction, carpentry, landscaping, painting, or cleaning, according to a separate statement Friday from Roberto Santamaria, the town’s health and human services director, and Gary Shaw, the president of Nantucket Cottage Hospital.

Monday to consider placing restrictions on some of those trades, Holdgate said.

The town will also increase visits and health inspections at construction and landscaping sites, she said.

The town is closing Tom Nevers Park from dusk to dawn and may close other town-owned recreational spaces during those hours, Holdgate said.

Holdgate said the evidence of community spread in Nantucket shows that “we have regressed in our mission to quell the spread of COVID.”.
