OVERLAND PARK, Kan. (AP) — A suburban Kansas City hospital has resumed taking new patients after it reported 18 cases of gastrointestinal illness with at least one of them preliminarily identified as norovirus.

The University of Kansas Hospital’s Marillac Campus in Overland Park said last week that 10 patients and eight staff members became ill with symptoms, including nausea, vomiting and diarrhea.

In a statement released on Sunday, the hospital said that the campus underwent extensive cleaning to combat norovirus and patients and staff had been free of symptoms since Thursday.

The hospital, which focuses on inpatient pediatric behavioral health services, became part of The University of Kansas Health System last year.
