People urged not to attend A&E at two Dublin hospitals
The Health Service Executive is appealing to people only to attend the A&E departments in Dublin's Mater and Beaumont hospitals in the event of a genuine emergency.
The body says the two hospitals have had to cope with a large influx of patients in recent days.
The Mater was also recently hit with an outbreak of winter vomiting bug which delayed a number of discharges and affected hospital resources.
People are being advised to contact their GP or GP out-of-hours service before attending hospital.
