With the coronavirus spreading rapidly in other large states like California, Florida and Texas, Mayor Bill de Blasio announced on Wednesday that New York City would not resume indoor dining at restaurants next week as anticipated.

The decision to indefinitely delay indoor dining, which was made in conjunction with Gov. Andrew M. Cuomo, comes as New York officials are increasingly concerned that the increase in virus cases in more than 30 states could trickle back to New York, which has managed to rein in the outbreak.

“Indoors is the problem more and more,” said Mr. de Blasio, adding, that “the news we have gotten from around the country gets worse and worse.”…

At a news conference later on Wednesday morning, Mr. Cuomo agreed that bringing back indoor dining in the city was “imprudent,” pointing to the rising rates of infection elsewhere that he said were “storm clouds on the horizon.”
