Minister for Higher Education, Simon Harris, said the government will announce further restrictions to reduce the spread of Covid-19 in Ireland on Monday.
It now looks likely that level 4 restrictions with some additions will be imposed after Minister for Higher Education Simon Harris said level 3 restrictions "have not worked".
Mr Harris told RTÉ's the Week in Politics that it is "a really anxious time for people" but added that the trajectory of the virus is now "a real concern" for both the Government and public health experts.
His announcement follows a failure of the government to reach a decision yesterday evening over a future course of action.
Senior public health officials including Chief Medical Officer Dr Tony Holohan briefed the government yesterday evening about the coronavirus situation across the country.
Twice now in two weeks, the National Public Health Emergency Team (Nphet) has recommended a move to Level 5 restrictions but the government has held off both times.
The Border counties, Donegal, Cavan, and Monaghan, were moved to level 4 restrictions earlier this week on Wednesday due to their high 14-day incidence rate and follows a rapid rise of Covid-19 cases in Northern Ireland.
Level 4 restrictions are the strictest possible next to Level 5 restrictions which would see the country move to the highest state of lockdown since Ireland's first attempts to suppress the virus since March.
The government has said the priority at this level is to keep schools and childcare services open while maintaining people's safety.
Read on to see what the new measures mean.
You can not have visitors from outside your own household.
No social or family gatherings should take place in other settings.

Services will be held online but places of worship remain open for private prayer.

No new juries will be sworn to hear trials at the Central Criminal Court if the government opts for a Level 5 lockdown.
Mr Justice Michael White today said that trials can continue during Level 4 restrictions, with juries to be selected from smaller panels to allow for social-distancing.
