Gov. Andrew Cuomo on Sunday called it “reprehensible” and “grossly negligent” to allow UK travelers to fly into JFK Airport without being tested despite a contagious new mutation of the coronavirus shutting down London.

“Right now, this variant in the UK is getting on a plane and flying to JFK,” Cuomo said in a call to reporters Sunday of the mutation UK Prime Minister Boris Johnson has warned could be 70 percent more transmittable.

“Right now. Today,” the governor stressed, calling for the feds to impose coronavirus testing of UK travelers at a “minimum,” if not an outright ban.

“Literally six flights a day. And all it takes is one person,” he said of the possible seed for the new strain’s spread.
