A total of 362 new confirmed cases have been reported over the past seven days.
On Thursday the number of ICU patients suspected of having of Covid-19 increased to 14 compared to three cases at the beginning of the month.
Government official Elizabeth Canavan said the decision to remain in Phase 3 of reopening was justified.
She said: "We knew that there would likely be some increase in the numbers, however in the last week or so things have shifted away from the trajectory we were on.
"We have had more cases every day, more cases nationally overall and increasing number of cases in vulnerable groups.
"We have have outbreaks in workplace settings, more young people are getting the disease and there has been a shift in location of the majority of cases from Dublin to other counties."
Daily cases
This comes as health experts are warning that Ireland could see tighter restrictions imposed because of increasing rate of daily cases.
In the past week and a half, since July 27th, the Republic has averaged 42.7 new confirmed cases per day. The worst day in that period being July 30th, with 85 cases.
Associate professor in Trinity College Dublin, Tomas Ryan, said there needs to be a change before the situation gets out of control.
"In a couple of weeks we could be in a situation quite similar to what happened in Melbourne or Aberdeen and no one wants to see that. Even beyond the next couple of weeks, as we move into September, we deal with bigger challenges than we have been facing, when schools open and pubs open.
"As winter comes and flu season comes, we need a more robust system to be doing this. We cannot be just walking a tightrope. We need proper guard rails."
