The Covid-19 Riddle: Why Does the Virus Wallop Some Places and Spare Others? (New York Times)

New York Times: The Covid-19 Riddle: Why Does the Virus Wallop Some Places and Spare Others?. “The coronavirus has touched almost every country on earth, but its impact has seemed capricious. Global metropolises like New York, Paris and London have been devastated, while teeming cities like Bangkok, Baghdad, New Delhi and Lagos have, so far, largely been spared. The question of why the virus has overwhelmed some places and left others relatively untouched is a puzzle that has spawned numerous theories and speculations but no definitive answers. That knowledge could have profound implications for how countries respond to the virus, for determining who is at risk and for knowing when it’s safe to go out again.”
