Level five restrictions will come into force from midnight on Wednesday for six weeks, the Taoiseach has confirmed.
Micheál Martin said there's some evidence current restrictions have been effective in slowing the growth rate of the coronavirus.
He said further action is now needed to prevent a 'grave situation' in the coming weeks.
He said if everyone follows the rules over the coming weeks there will be an opportunity for people to have some 'respite' during Christmas after a difficult year of restrictions.
It won't be the same Christmas we had but if we all pull together it can be a special time says Micheál Martin

Under level five, people will be asked to stay and work at home wherever possible, and to exercise within 5km of their home.
All but essential retail will close.
A graduated system of penalties is being examined to enforce the travel restrictions.
Some exceptions to the level five roadmap will be implemented.
Schools, creches and construction sites will all remain open, while elite and professional sport matches will be allowed continue.
A 'support bubble' system is being set up, allowing people who live alone to have close contact with one other household.
Weddings will also be allowed remain at 25 guests.
There will be an opportunity to review the restrictions in four weeks, to see if they are working effectively.
