The state of New Mexico is using cell phone data to track the movement of people within the state for data on whether people are abiding by stay at home orders, Gov. Michelle Lujan Grisham said during a Thursday evening press conference.

The state wants to screen truckers who are bringing in supplies and take their temperatures but doesn't have enough temperature readers to do so, Lujan Grisham said.

"We're really nervous that this virus will follow travelers into the state," she explained.

Lujan Grisham said the state is using road signage to let travelers from out of state know that many state parks are not open and small communities should not be visited.

The governor does not want people visiting tribal communities or pueblos and has put up signage to say so as well as diversions and road blocks.

Lujan Grisham said there is a concern that tourists will overrun small communities, expose them to the virus and buy many supplies needed by residents.

Some tribes have put curfews in place to help dissuade travel of members, Lujan Grisham said.
