Texas is among several states requiring coronavirus quarantines for travelers from New York and other hot spots

AP/Houston Chronicle:

States are pulling back the welcome mat for travelers from the New York area, which is the epicenter of the country’s coronavirus outbreak, but some say at least one state’s measures are unconstitutional.

Governors in Texas, Florida, Maryland and South Carolina this week ordered people arriving from the New York area —including New Jersey and Connecticut — and other virus hot spots to self-quarantine for at least 14 days upon arrival.

Connecticut officials have also pleaded with New Yorkers and others from out of state to avoid visiting unless absolutely necessary.

But, in the most dramatic steps taken to date, Rhode Island State Police on Friday began pulling over drivers with New York plates so that National Guard officials can collect contact information and inform them of a mandatory, 14-day quarantine.

Gov. Gina Raimondo ratcheted up the measures Friday afternoon, announcing she’ll also order the state National Guard to go door-to-door in coastal communities starting this weekend to find out whether any of the home's residents have recently arrived from New York and inform them of the quarantine order.

The Democrat had already deployed the guard to bus stations, train stations and the airport to enforce the executive order, which also applies to anyone who has traveled to New York in the last 14 days.

"I know it's unusual. I know it's extreme and I know some people disagree with it," she said Friday, adding that she has consulted with state lawyers.

"If you want to seek refuge in Rhode Island, you must be quarantined."

Raimondo maintains she’s within her emergency powers to impose the measures, but the American Civil Liberties Union has called it an "ill-advised and unconstitutional plan.”

I think a Presidential State of Emergency Order probably makes the move constitutional.  It creates a situation similar to marshall law to stop the spread of the coronavirus.  Florida was among the first states to require a quarantine for New York travelers with second homes in that state.
