The National Public Health Emergency Team has recommended the closure of non-essential retail from St. Stephen's Day.
The Chief Medical Officer has warned the spread of Covid-19 is "out of control" with the number of cases doubling in less than a week.
A further 938 new cases were confirmed last night with 13 additional deaths, while the R number has risen to between 1.5 and 1.8 - the highest since March.
300 of the new case are in Dublin, 110 in Cork, 72 in Limerick, 68 in Donegal and 41 in Kildare.
Across the region there are 38 cases in Galway, 20 in Mayo, 9 in Sligo and less than 5 in both Roscommon and Leitrim.
Restaurants and pubs serving food will close at 3 o'clock this afternoon as part of new restrictions - while hairdressers and barbers will also shut later.
But Professor Philip Nolan, chair of NPHET's modelling advisory group, doesn't think those measures will bring the virus back under control
