Hospitals at coronavirus hot spots around the country are reporting dire conditions as they deal with a surge in critically sick patients. In Detroit, photos obtained by CNN from an emergency room worker at Sinai-Grace Hospital show bodies of people who have died of COVID-19 being stored in vacant hospital rooms and piled on top of each other inside refrigerated holding units in the parking lot. The photos are from early April, when hospital staff say they were treating between 100 and 130 patients at a time.
