VISITING restrictions are currently in place at University Hospital Limerick due to a suspected outbreak of Norovirus, the winter vomiting bug. Visiting to all wards at the hospital is prohibited with the exception of critically ill patients. Children are not currently allowed to visit any patients and should be kept away from all areas of the hospital. Only parents or guardians will be permitted to visit patients in the Children’s Ark. A HSE spokesperson said: “The hospital regrets this inconvenience but it is necessary at this time to prevent the spread of these illnesses to both patients and staff.”
