The new quarantine requirement in New York, New Jersey and Connecticut would apply to any person arriving from a state with a positive test rate higher than 10 per 100,000 residents, or a state with a 10 percent or higher rate over a seven-day rolling average.
Currently, Mr. Cuomo said, those metrics would apply to Alabama, Arkansas, Arizona, Florida, South Carolina, North Carolina, Utah, Texas and Washington.
Mr. Cuomo said that enforcement would be up to each of the three states. In New York, he said, those violating the quarantine order could be “subject to a judicial order and mandatory quarantine.” A first violation could result in a $2,000 fine and a second would bring a $5,000 fine, he said, up to $10,000 for someone who causes “harm.”
The effect of the order may be largely symbolic. Even in places where out-of-state arrivals are already formally required to quarantine, there has not been widespread enforcement to make sure the rules were being followed.
“You could argue that even law is the honor system until you get caught,” Mr. Cuomo said. “You can violate the quarantine until you get caught,” he added, then “you’re in mandatory quarantine and fined thousands of dollars.”
Players from the Mets and Yankees who have been in Florida but are coming back to New York for an abbreviated and late spring training will not be required to quarantine, Mr. Cuomo said. The state had been working on separate “health protocols” with them since last week, he said.
Mr. Cuomo, who hosted the news conference from New York City, was joined via video link by Gov. Philip Murphy of New Jersey and Gov. Ned Lamont of Connecticut, all three Democrats.
