Eighteen residents at Monument Health Custer Care Center have tested positive for COVID-19, the hospital system said Monday. Another 30 residents have tested negative.

Those who tested positive have been moved to separate areas of the facility from the other 30 residents in order to “ensure their safety,” the health care system said in a news release.

“Most of the COVID-19 positive residents have no symptoms, and some have mild symptoms,” Monument Health public relations manager Stephany Chalberg said, noting none require hospitalization at this time.

Staff from other Monument Health facilities have been called in to care for the residents, and the residents’ families have been notified, Chalberg said.

Since March 11, all Monument Health long-term care and assisted living centers have been closed to visitors. Caregivers are required to screen for symptoms before beginning their shifts and residents are screened twice a day for fevers and other symptoms, Chalberg said.

State health secretary Kim Malsam-Rysdon said the Department of Health is “actively working with” Monument Health with additional review of infection control practices. She said the Center is taking appropriate action to minimize the impact of COVID-19 in the facility.
