The National Public Health Emergency Team (NPHET) is set to recommend reducing the number of households from which people can visit another home in Dublin.
The move comes as health experts hope to clamp down on the growing number of cases in Dublin, which was home to 107 of Thursday's 196 new infections.
Under the new guidelines, only six visitors from up to two other households would be permitted, instead of six from up to three.
However, it is up to the Government to decide whether or not they wish to introduce such a change.
Should the Government accept and implement the advice, it's expected the new rule would be in place for three weeks.
Dublin is the hardest-hit area in the country, with an incidence of 67.8 per 100,000 of population.
Limerick has also seen a big jump in the number of cases recorded recently, and is reporting an incidence of 63.1.
Kildare, which has already been forced to return to a form of lockdown, is next on the list with an incidence of 61.6.
However, this is significantly down from the peak of nearly 200 per 100,000 that prompted health officials to advise a local lockdown.
It is feared that the reopening of pubs on September 21 will add to the spread of the virus, particularly in the capital.
Further restrictions could be introduced in residential facilities to protect vulnerable people, RTE News reports.
