Three local electoral areas have Covid-19 incidence rates three times the national average, according to the latest LEA data.
Tullamore is the highest in the country, at 484 per 100,000 people, closely followed by Dublin's north inner city and Longford LEA.
The data covers the two-week period that ended on Monday, when the country's rate was 148.
11 LEAs had less than five cases during the 14 days, including two in Co Leitrim.
Sligo-Leitrim TD Marian Harkin says the government should consider regional restrictions in the coming weeks.
Ms Harkin said: “I think we should look at relaxing restrictions, let's say for example on a county basis where the 14-day incidence rate is below 50. There's actually three counties in that situation - Leitrim, Kilkenny and Cork - I think there is good reason to look at that.”
