The acting chief medical officer, Dr Ronan Glynn, has said that the COVID-19 situation nationally "is a matter of serious concern".
He made his comments after a further 470 cases of the virus were confirmed on Friday evening. This brings the total number of cases here to 37,063.
One more death from COVID-19 has also been confirmed, bringing the total number of deaths to 1,801.
Of the 470 new cases, 198 were in Dublin, 61 in Cork, 36 in Donegal and 19 in both Kildare and Limerick.
"NPHET is now recommending that no more than two households should meet at any given time. It is vital that everyone - families, friends and neighbours - limit the opportunities this virus has to move from person to person and stop the spread of the disease across households.
"Behave as though you have the virus and keep yourself and those around you safe - don't take a risk by organising or attending gatherings with more than one other household," Dr Glynn said.
Meanwhile, a record 934 new cases were confirmed in Northern Ireland on Friday afternoon, bringing the total number of cases there to 12,886.
The previous daily record in the North was 424.
Furthermore, one more death was also reported, bringing the total number of deaths there to 582.
