A possible move to level 4 restrictions for the entire country is possible as the National Public Health Emergency Team (NPHET) are meeting to discuss “an alarming rise in cases”.
Government sources have said the fact that the NPHET meeting lasted for several hours on Sunday, it is unlikely a decision will happen before Monday.
Sources have told the Irish Examiner it is more likely a decision will be put to Cabinet on Tuesday.
The fact NPHET decided it needed to meet on a Sunday is seen as significant and sources have indicated that a country-wide move to level 4 is “certainly possible” given the rise in cases.
Should NPHET feel it needs to make a recommendation, it will forward a letter containing that recommendation to Health Minister Stephen Donnelly who in turn will present it to Taoiseach Micheál Martin ahead of Cabinet.
Any recommendation will be assessed and there is a possibility an incorporeal Cabinet meeting could be tabled for Monday, should it be required.
