Many developed countries are putting programs at the heart of their efforts to keep the virus under control, using technology to identify those at risk of infection. One-third of Iceland’s population has already downloaded a new government-approved app that uses GPS to track users, who can give contact-tracing officials access to their data if they test positive for the virus. China was able to come out of lockdown thanks to its aggressive efforts to find and quarantine the infected, although it used draconian isolation policies that democracies would find hard to implement.General Motors Co. is considering a number of options for testing workers for the virus and is prioritizing tests with quicker turnaround for results, said Jim Glynn, the auto maker’s global chief of workplace safety. More than 95% of the company’s China stores are now open with limited hours and reduced seating, restrictions Starbucks could also implement in the U.S. as it returns to more normal service. Panera Bread Chief Executive Niren Chaudhary told his employees during a virtual company meeting Wednesday, that the fast-casual brand, which largely depended on dine-in customers, needed to find new revenue sources. Mark O’Meara says he hopes to open his two independent movies theaters in Fairfax, Va., by June or July. In addition to stepped-up cleaning, he’s considering limiting capacity to 50% at reopening. Venues will add a new shift to sanitize after janitors finish cleaning venues post-events, and cashless transactions and protective shields at all points of purchase will become the norm, he said.
