Dublin, Louth, Waterford and Donegal should move to level 4 restrictions, with the rest of the country moving to Level 3, according to a health expert.
It comes as the 14-day incidence rate in those counties continues to rise, while nationally it stands at 70.4 percent.
Louth is now over 100, with Donegal and Waterford in the 90s with Dublin North West over 200.
Level 4 restrictions would mean no visiting other households, only 6 people can attend a wedding and gyms and leisure centres would be forced to close.
DCU Professor Anthony Staines believes this would help bring the virus under control.
Incidence Rate
Dublin North West currently has an incidence rate of 204.7 over the last 14 days - with 425 new cases identified in that time frame.
Over 1800 cases has been reported in the capital over the last two weeks giving an incidence race of 138, nearly double that of the national rate.
Meanwhile in Donegal, its 14-day incidence rate jumped from 72.9 on Friday to 96.7 yesterday.
Louth is at 101.1, meaning it is the only county aside from Dublin to be over 100.
Waterford's incidence rate stands at 93.8.
