In New York, Governor Andrew Cuomo on Thursday announced plans to deploy thousands of workers to trace the contacts of everyone who’s tested positive for the coronavirus. Cuomo said he hopes to assign 30 “contact tracers” for every 100,000 New Yorkers. Billionaire former presidential candidate Michael Bloomberg will oversee the program.

Governor Cuomo also announced that, beginning May 6, the New York City subway system will be shut down between 1 and 5 a.m. each day to clean and disinfect subway cars and stations. It’s the first time in over a century of New York subway history that transit officials have canceled 24-hour service across all subway lines. The shutdown will exacerbate a crisis for thousands of unhoused residents of New York City, who’ve used subway cars as shelters of last resort.
