State leaders across the U.S. moved to expand testing for the new coronavirus, while lifting some restrictions on travel and business that have crippled the nation’s economy.


The moves come as confirmed infections topped 4 million across the world, and the U.S. death toll climbed above 78,000.

New York Gov. Andrew Cuomo on Saturday announced the opening of 22 new sites meant to provide coronavirus testing for thousands of residents and enable epidemiologists to trace the disease’s spread.

The sites will be housed at churches in low-income areas across the state and will target black and Hispanic New Yorkers, communities that have been disproportionately affected by the disease, Mr. Cuomo said.
