Visiting restrictions remain in place at hospitals across the Saolta Group - including Mayo and Sligo University Hospitals, University Hospital Galway and Merlin Park, Portiuncla Hospital in Ballinasloe and Roscommon University Hospital.
The visiting restrictions were introduced last Friday and will continue this week, as an infection control measure.
Members of the public are asked not to visit hospitals across the Saoltas group, other than end-of-life situations, and other exceptional circumstances, as agreed with the ward manager in advance of visiting.
Children in particular should not visit patients in hospital.
Nursing homes across the West are also severely curtailing visitors.
