The National Public Health Emergency Team will meet this morning to consider recommending more restrictions, due to high Covid case numbers and the worrying new variant.
The first Omicron case was confirmed here yesterday, while the five-day moving average of coronavirus infections is nearly 4,500.
A further 3,793 cases of the virus were confirmed yesterday evening, while 55 deaths from the virus were notified in the past week.
The Chief Medical Officer, Dr Tony Holohan, has appealed to people to make a concerted effort to reduce their social contacts for at least the next two weeks, and in turn reduce the incidence of the Covid-19 virus.
Dr Holohan has also renewed his appeal for people to isolate and arrange a PCR test, if they experience any symptoms of Covid-19.
It's not expected that harsh lockdown measures will form part of today's talks, but the emphasis instead may be on curbing socialising and reducing crowding in hospitality settings.
Advice on household visits is also likely to be considered.
Tánaiste Leo Varadkar told the FG parliamentary party last night he's not convinced new restrictions are needed, while Taoiseach Mícheal Martin told his party that "a combination of vigilance, reduced socialisation and an accelerated booster campaign" was needed.
The Government has already introduced some measures due to the new variant, including home quarantine from seven southern African countries.
