A sign posted in front of the emergency entrance of Harborview Medical Center gives thanks to health care workers during the coronavirus outbreak Saturday, March 28, 2020, in Seattle. Harborview and University of Washington Medicine are preparing a “surge plan” that will enable its hospitals to better respond to the coronavirus outbreak. Under the plan, ambulatory patients with respiratory illness symptoms will be separated from other patients when they arrive at hospitals’ emergency departments and be directed to a new treatment area in a tent outside of the emergency department.
