There have been a further 1,378 cases of COVID-19 reported in Ireland.
Today’s figures mean the five-day moving average now stands at 1,223.
It comes as the Tánaiste has warned Ireland could see up to 4,000 cases per day in the coming weeks due to the Delta variant of the virus.
The Department of Health says the variant "is much more transmissible than what we have been dealing with previously".
Deputy Chief Medical Officer Dr Ronan Glynn, meanwhile, says the latest estimate of growth rate of new cases is approximately 6%-7% per day.
He warned that hospital and ICU numbers will see a ‘significant increase’ if incidence rates continue to rise.
Incidence rates are increasing across the country & all counties have had more cases in the last 7 days than in the previous 7 days
