Visiting restrictions have been put in place, at six separate hospitals around the country, in an effort to prevent the spread of the flu.
Hospitals in Waterford, South Tipperary, Limerick, and Cork have all put a visitor plan in place.
Elective surgeries have also been cancelled in some locations and the public are being urged to visit their GP if they have flu-like symptoms.
