Health officials are concerned about the rising number of Covid-19 cases in Waterford.
NPHET is also particularly concerned about Louth and Donegal - where a third of recent cases are among 15 to 24 year olds.
A total of 234 new cases were identified yesterday, and a further two deaths were recorded nationally.
Acting Chief Medical Officer, Dr Ronan Glynn, says they are worried about the high numbers in Waterford:
"In Waterford, there has been a particular outbreak in one meat processing facility, and that accounts for about one third of the cases.......but that seems to be now under control."
