The Big Apple public school system will remain open Wednesday since the city’s latest coronavirus indicators have not yet triggered a shutdown, Mayor Bill de Blasio said Tuesday.

“New York City continues to hold on. New York City continues to fight back,” de Blasio said during a City Hall press briefing, adding, “Schools will be open today and schools will be open tomorrow in New York City.”

Hizzoner has been warning parents that the city’s entire public school system will close for in-person learning if the Big Apple hits or surpasses a 3 percent COVID-19 infection rate on a seven-day rolling average.

The latest city data shows that the city has a 2.74 percent infection rate on a seven-day rolling average, while the daily citywide positivity rate is at 3.2 percent.

On Monday, the infection rate on the seven-day rolling average was at 2.77 percent.

“Another day where we stayed below the threshold because of everything you have done,” de Blasio said of New Yorkers.

The city’s seven-day rolling average of new virus cases is at 1,117 — about double where the caseload was in October, the data shows.

There is “tremendous concern” about that figure, de Blasio said.

The latest data also shows that on Sunday, 102 people were admitted to city hospitals with suspected COVID-19 and 45 percent of them tested positive.

The percentage of hospital patients testing positive has increased, the mayor noted.

De Blasio said the city is seeing “record participation” when it comes to locals across the five boroughs getting tested for the virus.

Last week, more than 300,000 New Yorkers were tested with 75,000 tested on Friday alone.

“As more and more people are getting tested, we’re seeing the truth of what’s happening,” said de Blasio. “It is so important that everyone get out there and get tested.”

Meanwhile, de Blasio announced that more than 1.5 million New Yorkers have gotten their flu shot this year.

According to stats from the Department of Health and Mental Hygiene, there has been a 41 percent increase in the number of adults aged 19 and older who have received the vaccine so far this year compared to the same time period last year.

And there’s been a 23 percent increase this year in children aged 6 months to 18-years-old who got the flu shot, the statistics show.
