SINGAPORE -- From New York to Bangkok to New Delhi, some of the world's biggest cities are locked down to fight the new coronavirus. Singapore is an exception.
So far, at least, the city-state has avoided the curfews and sweeping business closures seen elsewhere during the pandemic. Tight border controls and strict tracing of COVID-19 patients are two reasons. But there is another key to the city's semblance of normalcy: a government-led "social distancing" or "safe distancing" campaign that is visible just about everywhere.
