Nantucket issues new face mask advisory for residents, visitors - WCVB Boston

Health officials say the decision to issue a new face mask advisory was made as a result of the increasing number of COVID-19 cases across Cape Cod and the islands of Nantucket and Martha's Vineyard.

The greater risk of infection from the delta COVID-19 variant also played a role in the decision.

"The increased virulence of the Delta variant, and its high ability to infect even those vaccinated in some cases, means that masking and distancing are strongly recommended at this time," a statement from Nantucket town officials said.
