The Government is to ban all household visits in an effort to hold back the second wave of Covid-19 in Ireland.
The move is one of a number of measures to be approved by Government ministers.
Visits will only be permitted on compassionate grounds and for essential reasons such as childcare.
Gatherings in home gardens are also outlawyed.
Up to six people from two households can meet outside in non-domestic settings while maintaining physical distancing.
The restriction is due to come into force on Thursday night.
