NEW YORK — New York City Mayor Bill de Blasio told the PIX11 Morning News Monday he fears the coronavirus crisis could keep city schools closed for the rest of the school year.

While NYC's 1.1 million students began a new remote-learning program Monday, the mayor said he "can't see" public schools reopening in April as initially planned.

City schools officially closed their doors on March 15, with de Blasio at the time predicting the earliest they would reopen would be April 20, a tune he's since changed as the city's COVID-19 cases have skyrocketed with more testing.

De Blasio also mentioned Monday he has no current plans to close any city streets, as Gov. Andrew Cuomo had suggested, but will unveil a new plan later Monday that deals with ways to keep New Yorkers from congregating in large crowds instead of social distancing.

The mayor also said he asked President Donald Trump and Vice President Mike Pence on a Sunday phone call to send military medical personnel to NYC and doubled down on the city's need for more medical supplies, including ventilators.

As of Sunday night, there were 10,764 positive COVID-19 cases and 99 fatalities, according to the mayor's office. About one-third of the COVID-19 cases in the entire nation are in New York City.
