Tánaiste Leo Varadkar has said a second lockdown will be more hard than the first and may not save Christmas after Nphet recommended Level Five restrictions for six weeks.
The Irish Times reports that NPHET made the recommendation to go to Level 5 to the government after a meeting on Thursday.
Galway is now at Level 3 along with most of the country, with additional restrictions on household visits, while counties Cavan, Monaghan, and Donegal are at Level 4.
1,205 new Covid-19 cases have been confirmed, along with three newly reported deaths.
The 14-day incidence rate for the country has now risen above 206 per 100,000 population, with the highest rates being recorded in Cavan (639 per 100,000) and Donegal (367 per 100,000).
There are now 241 confirmed cases in hospitals across the country (an increase of nine from yesterday), while there are 29 confirmed cases in the ICU.
In an update from NPHET, there's been a big spike in cases in the Shannon electoral area since the last release of a week ago, while Kilrush and Ennis have also experienced further significant growth.
According to professor Philip Nolan, if trends continue this way, by 31 October, we could be seeing 2,500 new cases notified daily, with over 400 hospitalisations. "That indicates a rapidly deteriorating disease trajectory nationally".
People would be asked to stay home, with no travel beyond 5km from your residence.
It brings the number of cases to date to 46,429, and the number of deaths to 1,205.
"The higher the community transmission the more hard it is to protect medically vulnerably people in all heathcare settings".
