Nenagh Hospital becomes the latest local medical facility to implement visitor restrictions amid covid-19 outbreaks.
In the past two days, both University Hospital Limerick and Tipperary University Hospital have introduced restrictions on visitors.
In Nenagh Hospital, an outbreak of the virus on Medical Ward 1 means visiting is not currently permitted in this ward.
Exemptions are in place for people visiting critically unwell or end-of-life patients along with patients with dementia, with those exemptions limited to one person per patient.
The hospital say they will review this decision on a daily basis and that visits to other areas of the hospital can continue as normal.
