There have been 1,861 new cases of COVID-19 in Ireland.
Latest available figures show 249 people have been hospitalised with the virus - 54 of these are in ICU.
There has been a total of 5,074 COVID-related deaths in Ireland.
The five-day moving average of cases stands at 1,749.
Dr Tony Holohan, Chief Medical Officer, says a significant number of those hospitalised are younger people.
"The number of patients with COVID-19 in hospital and ICU has continued to increase in recent weeks.
"At the moment, 43% of patients with COVID-19 in ICU are aged less than 50 years of age.
"This is a stark reminder to all of us to continue to adhere to the public health guidance and to ensure to receive both doses of COVID-19 vaccine as soon as it offered."
Dr Holohan says despite high vaccine rates, incidence of the disease is increasing across every group.
"In the main, we have seen very high vaccination figures in our population, particularly in the over-60s cohort who were offered their vaccines first.
"Unfortunately, incidence of disease is increasing across all age groups.
"COVID-19 vaccines are ensuring that those who are fully vaccinated are protected from the severe illness and poor outcomes related to this disease.
"For every fully vaccinated confirmed case of COVID-19, we know that vaccines are preventing about four other cases.
"We have shown time and time again in this country that we can break the chains of transmission of COVID-19 and continue to protect ourselves and our loved ones by supporting one another to adhere to the public health advice.
"If you display symptoms of COVID-19 like cough, fever, headache, sore throat and blocked or runny nose - isolate and get a test immediately.
"Continue to socialise safely by risk assessing, meeting outdoors where possible."
He adds: "Only meet up with small numbers of people and avoid crowds. Remember, it is OK to leave if you do not feel safe."
