A healthcare worker in the south of the country is one of the latest people to be diagnosed with coronavirus in Ireland.
She'd come into contact with a previously confirmed case and is among five new cases of Covid 19, bringing the total to 18.
There are now seven people in the west, seven in the east and four in the south being treated for the virus.
Deputy Chief Medical Officer Dr Ronan Glynn says everything is being done to protect healthcare workers.
Mayo University Hospital has implemented visiting restrictions which will continue into next week and will be kept under review.
These restrictions are being put in place as an infection control measure and will apply to all hospitals in the Saolta Group.
A hospital spokesperson stated, “We are asking the public not to visit the hospital other than end of life situations and other exceptional circumstances as agreed with the ward manager in advance of visiting. To arrange a visit, families should telephone the hospital and request to speak to the relevant ward manager who will decide if a visit can be facilitated without compromising the welfare of the patients on the ward. Children in particular should not visit patients in hospital.
“We recognise that the visiting restrictions may be challenging for patients and their families, however, our priority must be to protect the patients in the hospital who are vulnerable to infection. We would like to thank members of the public for their co-operation.”
