A further 613 new Covid-19 cases were announced in Ireland on Saturday as fears grow the pandemic is becoming out of control.
"Level 4" has been trending on Twitter in the country with speculation that the country may have to move up levels if things continue to worsen.
Dr Ronan Glynn warned on Saturday that the latest numbers represent a "significant escalation" of the virus here in Ireland.
However there were no suggestions that any immediate measures would be brought in with NPHET likely to discuss the concern when they meet on Monday.
Donegal and Dublin are currently at level three of the Living with Covid plan with the rest of the country at level two.
Some experts have even suggested that a move to level four is necessary to stop hospital and ICU numbers soaring.
But if Ireland needs to enter level four - what would that mean? Here's a look at that and the dreaded level five;
