St. Mary's General Hospital in Kitchener is partially lifting visitor restrictions on its fifth floor. 

The hospital had closed off the entire general medicine unit to new admissions and transfers on Tuesday, after a gastrointestinal outbreak was declared. It also restricted visitation to one visitor per patient at a time. 

According to a hospital news release, six patients and six staff became ill during the outbreak. The hospital says two patients were already sick when they arrived at the hospital. The rest became ill after arrival. 

The hospital says only one patient continues to exhibit symptoms of gastrointestinal illness. As a result, half of the fifth floor will be re-opened today.

Patients in the open half of the fifth floor will be able to receive two visitors at a time. Visitor restrictions remain in the closed section of the unit.
