A patient who sought care at Northern Light Eastern Maine Medical Center’s walk-in care center on Union Street in Bangor has tested positive for COVID-19, the disease caused by the novel coronavirus.

The hospital said Wednesday afternoon that the Maine Center for Disease Control confirmed that one of the walk-in care center’s patients tested positive for the virus. The patient is in self-isolation and has not required further care at EMMC facilities, the hospital said.

Earlier Wednesday, the Maine CDC confirmed the first positive test for coronavirus in Penobscot County.

“We know this is likely the first of many patients we will care for with a positive diagnosis,” EMMC President Rand O’Leary said.

The walk-in care center remains open, and staff at the location were ready for potential COVID-19 patients, said EMMC spokesperson Amy Kenney. Staff at the center saw a patient with coronavirus symptoms — which include fever, cough and shortness of breath — on Friday, she said.

“Our staff cared for this patient in a manner that is consistent with CDC guidelines in order to minimize the risk to our patients and care team,” Kenney said. “At this time, we do not believe there is a reason for any increased measures for patients or staff, who have visited our location outside of what is being asked of all our community members.”

Elsewhere in the Northern Light Health hospital system, a worker at a Mercy Hospital practice in Portland tested positive for the novel virus earlier this week, shutting down two of the hospital’s affiliated, off-site practices.
