Under the new mandate, travelers from nearly every state in the union must show proof of a negative test taken within three days of arriving in New York, and must also quarantine for three additional days — and get a new COVID-19 on the fourth day.

If that’s positive, they must isolate for two weeks, the governor said at an Albany press briefing.

“Four days plus three days is seven days, and that’s basically, by all probability, the incubation period,” Cuomo said, as he announced 2,049 new cases across the state and 8 deaths yesterday.

“There will be no metrics. There will be one rule that applies across the country,” the governor said.
