If you're wondering how it's going in the US when it comes to containing COVID-19, Chicago Mayor Lori Lightfoot summed it up in a statement on Thursday. "This is literally a matter of life or death," she said, in the course of issuing a stay-at-home advisory effective from Monday at 6 AM. "We all have to step up and do our part." For Chicagoans, that means only leaving home for work, school, medical treatment, or food. Gatherings at home with people from outside the household are discouraged.
