In the face of surging coronavirus cases in New York City and elsewhere around the world, Gov. Charlie Baker is asking all visitors to Massachusetts and all travelers returning to the state to self-quarantine for 14 days.

Travelers landing at Logan Airport and arriving at Boston’s South Station will be handed fliers outlining the request, Gov. Charlie Baker said at a Friday morning press conference. Signs will be posted on the state’s highways, as well, and fliers will be available at rest areas. Baker said there will be no penalty or enforcement mechanism, but emphasized that the instruction was intended to prevent more COVID-19 cases in Massachusetts.

“Please do not travel to our communities, for whatever reason, especially if you have symptoms,” Baker said, but acknowledged the state may face constitutional challenges to taking stronger action.

While the move will likely do little to alter hotel occupancy rates, which are in the single-digits in some Massachusetts hotels, or business travel, which has already dropped off for all but the most critical trips to attack the coronavirus pandemic, but could crimp high-end home sales and leases as potential overseas or out-of-state buyers arrive to visit a property in-person.

Federal officials say anyone who has left New York City in recent days should self-quarantine for 14 days.

New York City has emerged as a “hot spot” in the cononavirus pandemic, reporting 21,873 infections, 281 deaths and at least 3,900 hospitalized as of Thursday. City and state officials are in the process of converting the city’s 1.8 million-square-foot Jacob K. Javits Convention Center into temporary hospital space to deal with the flood of potential coronavirus cases.
