Until recently, it seemed like the contentious debate over lockdowns was over. By the end of May, many states were defying the warnings of public-health experts, reopening restaurants, retail and public spaces. The huge protests against police brutality and racism reinforced the notion that keeping Americans confined to their homes was a lost cause. Now, even San Francisco, one of the first cities to issue a stay-at-home order, is proceeding with a phased reopening of businesses and public spaces.
But reopening always came with a question mark. With the coronavirus still out there, would cases rise if stay-at-home orders were lifted? And if that happened, would lockdowns have to come back?
