Many Americans in recent weeks have begun working remotely, if they haven’t been furloughed or laid off; schools have canceled classes for weeks; and restaurants, retail stores, bars, gyms, and other gathering places in dozens of states have shuttered. Major events were called off with a domino-like effect, including Coachella and South by Southwest, March Madness and virtually all national sporting events, and many religious services across the country. Now at least 42 states have stay-at-home directives.
