There have been 13,765 new cases of Covid-19 reported by the Department of Health.

The department has 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.

They added that the data is provisional.

The total of 13,765 represents the highest ever total announced, overtaking the 11,182 cases announced yesterday.

There are 378 patients with Covid-19 in hospitals around the country.

It represents a decline of 15 from yesterday, and is the lowest number of Covid patients requiring hospital treatment since 9 October when there were 353 people with Covid receiving hospital treatment.

87 of these patients are being treated in intensive care units, down two from yesterday.

The Department of Health estimates that 83% of cases are now attributable to the Omicron variant.

Meanwhile, the Health Service Executive has said Covid-19 vaccination clinics around the country are closed for Christmas Day and St Stephen's Day.

However, PCR testing will continue to be offered this weekend although there will be a slightly reduced level of service.

Vaccination centres will resume service on Monday 27 December.

Yesterday, the Chairman of the High Level Task Force on Covid-19 Vaccination said that 400,000 doses had been administered this week.

Professor Brian MacCraith added that two million booster shots or third doses had now been given, surpassing the target of administering 1.5m doses by Christmas Day.
