Gov. Andrew Cuomo on Friday called on New Yorkers to “kick coronavirus’ ass” as the state braces for the anticipated “apex” of the crisis in three weeks.

The call to arms came as Cuomo said the state’s death toll from the disease had reached 519, and would continue to rise because the prognosis for the most seriously sick victims was so grim.

“We go out there today and we kick coronavirus’ ass, that’s what I say, and we’re gonna save lives and New York is going to thank you,” Cuomo declared during a news conference at Manhattan’s Javits Center.

Cuomo said he’d struck deals to convert the swank New York Marriott at the Brooklyn Bridge hotel, the Brooklyn Center rehab facility and dormitories at the City College of New York in Harlem and Queens College for use as emergency medical centers, if needed.

Those projects would all be funded with state money, he said.

Cuomo also said he would ask President Trump later Friday “if he will authorize another four temporary hospitals for us” to be built and run by the Federal Emergency Management Agency so there can be one each in all five boroughs, as well as Nassau, Suffolk and Westchester counties.

The four sites that will go to Trump for approval are the Brooklyn cruise terminal, Aqueduct Racetrack in Queens, the New York Expo Center in The Bronx and the College of Staten Island, he said.

FEMA has already started putting a total of 4,000 hospital beds at the Javits Center in Manhattan, SUNY Old Westbury in Nassau, Stonybrook in Suffolk and the Westchester County Center in White Plains.

The state is also desperately collecting N95 respirators, protective gowns, coveralls and ventilators.

“We want to do everything we can to be ready for that increased capacity that could hit us in 21 days,” Cuomo said.

“We’re creating a stockpile of this equipment so if and when the apex hits, we can deploy equipment from the stockpile to whatever region of the state or whatever hospital needs it.”

But Cuomo also warned that the state had yet to suffer its worst losses from the deadly pandemic.

“That is going to continue to go up, and that is the worst possible news that I could tell the people in the state of New York,” Cuomo said.

“The longer you are on a ventilator, the less likely you are going to come off that ventilator.”

He added, “It’s bad news, it’s tragic news, it’s the worst news — but it’s not unexpected news, either.”
