There have been 783 new cases of COVID-19 reported in Ireland today.
It's the first time more than 700 cases have been reported in a single day since April 1st, and the highest daily case number since February.
The five-day moving average of new cases now stands at 626.
Commenting on today's figures, Deputy Chief Medical Officer Dr Ronan Glynn said: "The latest data is showing clear increases in incidence of disease right across the country.
"There is no question that the delta variant is having a considerable impact of transmission of COVID-19."
The Delta variant is now responsible for most cases in Ireland, with Professor Philip Nolan saying it's "at least twice as transmissible" as the previously dominant variant.
Infections are said to be growing at 2-4% per day.
The latest figures show there are 73 patients with COVID-19 being treated in Irish hospitals today.
That figure includes 20 patients being treated in intensive care.
As of today, over 58% of all adults are now fully vaccinated, with a total of five million vaccine doses set to have been administered by the end of this week.
Chief Medical Officer Dr Tony Holohan said young people are suffering "a great burden as they wait for their vaccinations".
He urged everyone to continue exercising caution when meeting others.
