ALBANY, N.Y. (NewsNation Now) — Starting Wednesday, New York will require travelers from non-neighboring states to get a coronavirus test before, and after, they arrive in the state if they want to avoid a full 14-day quarantine.

New York for months had attempted to maintain a list of states with high COVID-19 infection rates, where travelers from those states would be required to quarantine for 14 days upon arrival. It is now scrapping that effort amid a nationwide rise in coronavirus cases.

Instead, Gov. Andrew Cuomo said Saturday travelers from all non-neighboring states who don’t want to quarantine for two weeks must test negative for COVID-19 no more than three days before they enter New York.

Individuals arriving without proof of a negative test won’t be stopped from entering the state, but will be required to quarantine for 14 days.

Individuals who tested negative will still have to quarantine for three days after they arrive and then take a second test. If that’s negative, they can stop quarantining.

Travelers who decide not to get tested will be required to quarantine for 14 days, the governor said.

Cuomo said enforcement would be up to New York airports and county health departments, but didn’t lay out exactly how that would happen.

New York’s existing quarantine requirement for travelers has proven to be largely unenforceable.

Cars travel freely across the state line daily without anyone checking to see where the people in the car have been. Travelers by plane, train or bus are told they have to quarantine, but there is no substantial follow-up where they have to prove they have done so.

As a result, the rules have been widely ignored, raising the likelihood that the new testing requirement will also be widely flouted.

The rules don’t apply to neighboring states, though Cuomo has also urged New Yorkers to avoid nonessential travel to those states. Pennsylvania, Massachusetts, Connecticut and New Jersey are also seeing an uptick in cases along with New York.

New Yorkers who are out-of-state for less than 24 hours only need to take a coronavirus test within four days of returning to the state.

“They do not need to take a test before getting on the plane to come back to New York,” Cuomo said.

New York, New Jersey and Connecticut had announced a joint travel advisory this summer when the Northeast saw fewer COVID-19 positive cases than the rest of the nation. States qualified for the quarantine list if they had averaged 10 new cases daily per 100,000 residents.

Cuomo acknowledged it’s becoming increasingly difficult to enforce the travel advisory, despite his push to fine airport travelers who don’t fill out contact tracing forms.

“The list started small and then the list got longer and longer and longer,” he said. “At one point it was no longer a list, it was all inclusive. Now, you don’t have a list.”
