The town’s Board of Health has requested seasonal residents from New York City isolate themselves at home for 14 days after returning to Dartmouth to prevent the spread of Covid-19 in the area.

In a notice posted on the town’s website, the Board stated “Many seasonal residents, including homeowners, visitors and tenants, have decided to return to the Town of Dartmouth several months early. Some seasonal residents may be departing urban areas such as the New York City area, which has a high number of cases of Covid-19...We are requesting that all returning residents and or occupants from the New York City area stay home for a period of fourteen (14) days.”

The Board noted that these rules are part of “unprecedented efforts” to slow the spread of the illness, which had killed 25 in Massachusetts as of March 26.

Bristol County now has 90 confirmed cases.

They asked seasonal residents from New York to stay at home or on their property, have groceries delivered to their doorstep, keep a social distance of six feet from others, and not host or attend any social gatherings at any residences during the 14-day period.

Returning residents should also monitor themselves for fever, cough, or shortness of breath, the board’s statement continued, and contact their doctor by phone if they start showing symptoms.

The isolation period begins on arrival in Dartmouth and ends after the 14th day.
