The Department of Health has been notified of 1,627 new coronavirus cases.
There are 415 people with the virus in hospital, an increase of seven since yesterday. The number of patients in intensive care is up one at 70.
The Deputy Chief Medical Officer has said that there is an increase in the incidence of the disease across all age groups, including older age groups.
Dr Ronan Glynn said that the national incidence now stands at 415 per 100,000.
He said: "As a result, we are seeing an impact on our hospital system with an average of 50 people being admitted to hospital per day (up from 35 per day at the end of September) and five admissions to intensive care per day.
"It's important that anyone who is fully vaccinated is reassured that vaccines give very good protection from Covid-19.
"However, when incidence of disease is high, we will see breakthrough infections in vaccinated people - most people’s experience of infection will be mild, but some will end up in hospital and intensive care. We want to avoid that."
Dr Glynn has urged people to continue adhering to public health advice, and stay at home if they have any Covid-19 symptoms. "This applies even if you are fully vaccinated - please do not assume that because you are vaccinated you can't get Covid-19," he said.
President of the Royal College of Physicians of Ireland ,Mary Horgan, has said that it is a "time to pause, look at the data - it's not a time to panic."
Speaking on RTÉ's Drivetime, Ms Horgan said: "I think we need to pause and not rush into a big analysis saying that we're rapidly deteriorating.
"We have a vaccinated population that is the envy of most people in the world," she said.
Meanwhile, the overall number of Covid-19 outbreaks reduced in the week to last Saturday, new figures show.
There were 174 outbreaks, compared with 203 the previous week. An outbreak is two or more linked cases.
Nineteen workplace outbreaks led to 88 confirmed linked cases, while 13 nursing home outbreaks led to 123 confirmed linked cases.
There were ten outbreaks in acute hospitals, resulting in 37 confirmed linked cases.
Three school outbreaks were reported, with 15 confirmed linked cases. Two of the outbreaks were in primary schools and one in a special education school.
The report is from the Health Protection Surveillance Centre (HPSC).
The Health Service Executive's Chief Operations Officer said that the number of cases of Covid-19 is up 43% in the last week, with the highest numbers of infections among those aged between 19 and 44 (just under 40%) and those aged 0-18 (26%).
Speaking on RTÉ's Morning Ireland, Anne O'Connor said the majority of patients with Covid-19 requiring admission to hospital and into ICU are not vaccinated, and that the unvaccinated 10% of the adult population is driving 50% of admissions.

Ms O'Connor said "cases are growing ... and it is really important that people see that is why we are giving a third vaccine to the over 80s, to those in nursing homes and the immunocompromised".
She said a changing picture in recent weeks is that more people are needing admission to hospital.
"There are more sick people turning up, who need to be admitted to hospital for a whole range of reasons including increased frailty and people who are just sicker."
Ms O'Connor said hospitals, particularly in Galway, Limerick and Cork, are under pressure there were less than 100 beds available across the whole system last night.
On the planned easing of restrictions next week, HSE chief operations officer Anne O'Connor says there are concerns around health service delivery with numbers with Covid-19 in hospital remaining "stubborn" at around 400 | Read more: https://t.co/iqZY1MW3yy pic.twitter.com/Cfc13nHJqn— RTÉ News (@rtenews) October 14, 2021
