New York City’s public hospital system quietly suspended elective surgeries earlier this week to free up ward space for coronavirus patients as testing positivity rates and the number of new cases continue to surge, officials revealed Thursday.

The decision came Tuesday as the city’s average positivity rate continued to spike. By Thursday that rate hit 6 percent for the first time since May and both Mayor Bill de Blasio and Gov. Andrew Cuomo warned that they may order additional lockdown measures by the end of the holidays if the rush of new COVID-19 cases doesn’t slow down.

“The virus keeps causing us a challenge, the rate of infection keeps going up in this city, hospitalizations keep going up,” de Blasio said Thursday.

“We’ve got a serious issue here.”

Asked Thursday about a possible shutdown after the holidays, de Blasio got more specific.

“Yeah. Look, I’ve been talking to our health care team throughout. Everyone’s very concerned about the increase in the number of cases, we report it to every single day, very openly. The number of cases is too high. The, the infection levels too high. The number of hospitalizations is too high and unfortunately it’s just growing,” the mayor said.

“I don’t like restrictions. None of us likes restrictions, but I think we need them sooner rather than later … and certainly right after Christmas is a natural moment when the world kind of slows down a little bit. But we’ll keep having that conversation with the state to figure out exactly how they want to proceed.”

The head of the Health + Hospitals Corporation, Dr. Mitch Katz, also said Gotham’s 11 public hospitals have transferred more than 100 coronavirus patients to other facilities with more space to prevent the sites from being overwhelmed by the initial influx.

“We’ve made it clear that the only surgeries we will be doing are those surgeries where they come in emergently, such as car accidents, or surgeries where somebody’s health is directly infected — like when someone has an infection,” the hospitals chief added.

He added that the public hospital system began planning for the non-emergency surgery shutdown over the weekend and had suspended them effective Tuesday.

However, a spokesman for H&H said late Thursday that the state had since updated its capacity criteria for the coronavirus, allowing the public hospital system to resume elective procedures for the time being.

Overall, roughly two-thirds of the intensive care and traditional hospital beds are currently full.

The disclosures came as statistics from the city Health Department revealed the seven-day average positivity rate for coronaviruses administered in the five boroughs continued its climb, hitting the 6 percent mark for the first time since May.

And officials said the city is now averaging more than 2,700 new cases of COVID-19 every day.

“We’ve got a long way to go and everyone needs to be part of turning it around,” said de Blasio.

Cuomo echoed those sentiments upstate Thursday morning when asked about the surge in cases during a snowstorm press conference, where he again beseeched New Yorkers not to travel or gather in large groups indoors during the holidays.

“We want to slow the spread, we want to avoid shutdowns and together we can do it,” the governor said.

“How do you slow the spread?” Cuomo continued. “We’re smart during the holiday season.”
