Facing an increase in coronavirus infections in certain neighborhoods, New York City Mayor Bill de Blasio announced Sunday that he would close all nonessential businesses, public and private schools, and daycares in nine ZIP codes throughout Brooklyn and Queens, to ensure that the virus doesn't spread further. … After initially leading the nation in positive coronavirus tests, New York City was able to get the virus under control earlier this year through strong messaging on the importance of social distancing and the widespread closures of businesses. But in recent weeks, city officials and residents had been watching the numbers tick back up, particularly in Orthodox Jewish areas. The areas de Blasio mentioned in Brooklyn and Queens have been above a 3% positivity level on testing for seven or more consecutive days.
