COLUMBUS, Ohio — An employee in the Child Care Center at Nationwide Children’s Hospital has tested positive for coronavirus, according to a statement from the hospital on Wednesday.

According to a spokersperson for the hospital, the employee recently worked for two days while "largely asymptomatic" and called in sick Wednesday morning after experiencing symptoms. She was immediately tested Wednesday at Nationwide Children's on-site testing center and lab.

The employee worked with two other staff members and 11 children. The staff and families of the 11 children have been notified and were asked to isolate at home for 14 days while they are monitored for symptoms, the hospital said.

"Although no other children are believed to have had contact with this employee, approximately 150 other families whose children are served by the center were notified of these events and will be monitored by the hospital," the hospital said,

The Child Care Center is closed effective immediately and until further notice.

"The hospital will work with these families to offer them support that is most needed and helpful," the hospital said.

"Nationwide Children’s is deeply concerned about all children and staff impacted by this difficult news and will continually monitor and support each child and family. As we embrace our coworkers and their children, we are encouraged that the hospital’s notification and testing protocols worked as intended including our ability to conduct rapid testing on-site," a statement from NCH read in part.
