The Department of Health has been notified of a further 6,735 cases of Covid-19 in Ireland.
The number of people in hospital with the virus stands at 461, which is up 35 on yesterday.
Of these patients, 91 are being treated in ICU – unchanged since yesterday.
In a tweet, the department said: “In anticipation of large volumes of case numbers over the coming period the daily case number announced will be based on positive SARS-CoV-2 results uploaded to the HSE Covid Care Tracker the preceding day. These data are provisional.”
It estimates that approximately 87% of reported cases are now due to the Omicron variant.
The HSE said all 41 of its Covid-19 testing centres have fully reopened after a portion were closed and others operated reduced hours over the past two days.
Vaccination centres have also fully reopened following a two-day Christmas closure.
The Department of Health estimates that more than 83% of cases are now attributable to the Omicron variant.
Meanwhile despite Government advice that up to four households can meet indoors over the Christmas period, the Chief Medical Officer has now appealed to people not to socialise or meet indoors with people from other households.
Dr Tony Holohan also asked people to avoid crowded places, including retail environments.
