Of today's new cases, 128 were in Dublin, 45 in Cork, 43 in Waterford, 36 in Limerick, 24 in Donegal, and 24 in Meath, with the remaining cases spread across 20 other counties.
As of this afternoon, there were 258 COVID-19 patients in Irish hospitals - including 35 in ICU.
Chief Medical Officer Dr Tony Holohan said: “The increase in case numbers of COVID-19 today is an important reminder of the unpredictable nature of this highly infectious disease.
"The hard work undertaken by all of us over the last three weeks is to be commended, but we must not allow our success to date let us drop our guard against the spread of this disease."
However, he emphasised that if people keep up the high level of compliance with restrictions "we can get to where we need to be on the 1st December".
The national incidence rate of the virus now stands at 129 per 100,000 - the third lowest rate in Europe.
Donegal has the highest 14-day incidence rate in the country - but has fallen slightly to 270 per 100,000 population today.
