New York City public schools are open for blended learning, but it's not clear how long that will be the case.

With COVID-19 rates rising in NYC and across the state, city and school officials are monitoring the numbers closely.

The latest data shows the city's infection rate at 2.57%, with just a 0.18% rate in schools. If the latter hits 3%, schools would be forced to close.

This comes as the state concludes its first weekend with a 10:00 p.m. indoor-service curfew on restaurants, bars and gyms, plus a capacity limit of 10 people on private gatherings.

President of the United Federation of Teachers Michael Mulgrew told NY1 teachers and administrators are doing everything they can to keep students safe — from masks to social distancing to cleaning — but keeping schools open, he believes, requires a united, "renewed effort" from every New Yorker.

"I understand people's frustration. I understand when people say to me, 'Why is the restaurant open?' That is not — our choice here with the teachers is to make sure that we do everything to keep those schools safe, and I'm very proud of the teachers of New York City because they really put their butts on the line — something nobody else in the country has done, which is to get the schools open safely,” said President of the United Federation of Teachers Michael Mulgrew.
