Visitors are being asked to stay away from the hospital in all but exceptional cases
Tallaght Hospital has imposed visitor restrictions due to an outbreak of the winter vomiting bug.
With the exception of critical ill patients and children, people are being asked not to visit anyone currently being treated there.
In particular, children are not permitted to visit patients at this time.
Management says the outpatients clinic and emergency departments are both operating as normal, however anyone with vomiting or diarrhoea is asked to phone the hospital to rearrange appointments or their GP for advise.
Tallaght Hospital says it'll keep the situation under review.
