"If you're starting to feel really short of breath, coughing a lot and developing fever – especially if you've had exposure to somebody who either has had COVID-19 or if you've been in a place or situation where you might have been exposed – then it's a good idea to go to the emergency department," says Dr. Darlene Tad-y, vice president of clinical affairs for the Colorado Hospital Association and a hospital medicine physician at UCHealth University of Colorado Hospital [and CU School of Medicine].
