The Department of Health has been notified of 3,161 new cases of Covid-19.

There are 498 patients with the virus in hospital, which is 20 more than yesterday. The number in ICU has risen by three to 78.

In Northern Ireland, 1,028 positive cases and 11 deaths have been reported in the past 24 hours.

In a statement, Chief Medical Officer Dr Tony Holohan said: "I encourage anyone who has yet to be vaccinated to come forward for vaccination. It is not too late to become part of our vaccinated pool of people and your participation in the Covid-19 vaccine programme will be welcomed.

"We are now also boosting and offering a third vaccine dose to healthcare workers and people over the age of 60. We are beginning to see encouraging signs, in the decreasing levels of infection among those age groups that have received their booster dose.

"The importance of coming forward cannot be overstated. If it is time for your booster, please come forward to receive that booster."

More than 52,600 third doses of Covid-19 vaccine have been administered to people under 60 who are immunocompromised, the latest HSE figures show.

There are around 90,000 people in this group due to get the extra dose.

The vaccination of immunocompromised people began in late September and is due to take around six weeks to complete.

The Cabinet sub-committee on Health met this evening to assess some of the wider challenges facing the health service - including the department's winter plan and waiting list numbers.

The meeting was not focusing on Covid-19.

The three Coalition leaders, along with the Ministers for Health, Finance, and Public Expenditure and Reform usually attend such meetings - however the Green Party leader Eamon Ryan is currently in Glasgow attending the COP.

Meanwhile, people stuck on hospital waiting lists will continue to have to wait while the number of people in hospitals with Covid-19 remains high, the President of the Irish Medical Organisation has said.

It comes after the IMO warned yesterday that healthcare services are being hit by a "perfect storm".

Dr Ina Kelly told RTÉ's Morning Ireland that while it is fortunate that hospital numbers appear to be stable enough despite the high level of community transmission, they are very high and continuing to put pressure on exhausted staff.

For every bed that is taken up with Covid, that is a bed denied to people with other illnesses and people on waiting lists, she said.

Dr Kelly pointed out that there are nearly a million people on waiting lists. She also warned people against vaccine complacency.

The President of the Irish Association of Emergency Medicine has also said that Covid patients are taking up a lot of acute bed and critical ICU capacity in hospitals.

Dr Fergal Hickey, a consultant in emergency medicine in Sligo University Hospital, said EDs are busy and there are a large number of patients on trolleys.

Speaking on RTÉ's Today with Claire Byrne, he said the situation is only going to get worse throughout the winter months and urged everyone who has yet to get the vaccine to receive it.

Meanwhile, the Department of Health confirmed that a mandatory one day a week attendance at its offices has been suspended temporarily.

Staff were informed of the decision last Thursday.

The department said that attendance is now limited to specific business purposes, as determined by management in the various divisions, pending further review.

It said that staff will continue to attend the department where necessary, but will not be required to attend where work can be undertaken remotely.

The department said that given its leadership role in the public health response to Covid-19, a range of staff have attended on site throughout the pandemic and will continue to do so.

Last month, the department started the process of bringing all other staff who had been working remotely back to the office "on a phased and cautious basis", with attendance one day a week, subject to review.
