Nemadji Golf Course in Superior will close its clubhouse and restaurant after a staff member tested positive for COVID-19.

While the golf course will remain open, people wishing to play golf will have to check in at the window of the golf shop. Food orders can be made for pickup and beverage carts will continue to operate.

The staff member's work area has been closed and will be "deep cleaned and disinfected" and any staff that came in contact with the infected person will be tested, the golf course said.

"We are taking these steps out of extreme caution and to comply with our COVID-19 guidelines," the golf course said on Facebook. "The safety of our guests and staff is always our highest priority."

According to the golf course, the staff member is not currently showing any symptoms of COVID-19 and will self-quarantine and not return to work for more than two weeks after reporting at least two negative tests.

The announcement comes during a surge of COVID-19 cases in Douglas County and as a number of bars in the Superior voluntarily closed after people associated with the locations tested positive for COVID-19.
