NEJM talks with Dr. Julian Flores, who works in a Broward County, Florida, emergency room.

When he was interviewed, the count of Covid-19 cases stood at 412, less than 12 hours later, the new number was 505. He’s expecting the wave to hit hard there. Broward is home to Fort Lauderdale (think spring break) and Pompano Beach (think aging retirees). Couple those demographics with a lack of easy testing for the virus, and you’ve got a worrisome situation.
