OSAGE — Mitchell County health officials confirmed over the weekend that a hospital health care employee has been diagnosed with COVID-19. A news release from the Mitchell County Department of Public Health says the Mitchell County Regional Health Center employee, who is not a resident of the county, was asymptomatic while working and is self-isolating at home. The employee will not return to work until completing the isolation in accordance with public health guidance.

Health Center CEO Shelly Russell says those who had close contact with the infected employee have been notified and clinics in Osage and St. Ansgar are still scheduled to be open today.
