Nine counties now have a 14-day COVID-19 incidence rate of more than 100 per 100,000 population.
The rate is calculated by looking at the number of cases over the past 14 days and giving a figure based on 100,000 population.
With level three restrictions set to come into effect for the entire country from midnight, latest figures show a national incidence rate of 114.
Cavan, Clare, Cork, Donegal, Dublin, Longford, Monaghan, Offaly and Roscommon have all passed the 100 mark, according to the latest figures from the HPSC.
Donegal remains the county with the highest rate of incidence with its figure at 273, followed by Monaghan on 206.
Dublin's rate currently stands at 167 per 100,000, while Offaly has just narrowly passed the threshold.
After being a county of concern for a number of weeks, Waterford has seen its 14-day incidence rate fall for six days in a row.
It is now the county with the lowest rate of transmission in the country, with an incidence rate of 29.3 per 100,000 people.
Concern has been raised by the National Public Health Emergency Team in recent days about hospital capacity with the rise in COVID-19 cases.
This morning, the HSE confirmed there are 150 people in Irish hospital diagnosed with the virus - a 28% rise on last week's figure, with nine admissions in the last 24 hours.
Latest figures show there are 24 confirmed COVID-19 cases in Ireland's intensive care units.
Health Minister Stephen Donnelly earlier moved to reassure people about ICU availability - saying there is significant surge capacity if needed.
However, he stressed that even in the first wave of coronavirus authorities 'didn't come close' to needing all of the available ICU capacity.
