ROSEBURG, Ore. -- Douglas County reported their third workplace outbreak on Tuesday, and it happens to be a Mercy Medical Center.

Kathleen Nickel, a spokeswoman for the hospital, told KEZI 9 News via email that only one employee has tested positive so far. However, they said there are six employees who are still considered presumptive.

Nickel said they believe the one positive employee contracted the virus while they attended an event on their day off. She said the employee was in contact with an out-of-state traveler who later tested positive. Nickel also said it’s likely attendees at that event weren’t wearing masks or social distancing.

The employee reportedly then came in contact with the six presumptive employees after returning to work.

Right now, all seven employees are quarantining for two weeks. Nickel said no patients came in contact with the employees while inside the building.

In a statement, public heath officer Bob Dannenhoffer said they are working closely with the hospital to get the outbreak under control.

"We believe it is still safe to seek care at Mercy because they were prepared and they are supporting additional testing while also supporting their staff in quarantine,” said Dannenhoffer. “We are working together to mitigate the transmission to staff, patients as well as the larger community."

The two other workplace outbreaks are at ROMTEC near Glide and Norris Farms outside of Roseburg.
