The Department of Health has announced 164 new confirmed cases of the coronavirus.
It comes as zero more deaths linked to Covid-19 have been recorded in the Republic of Ireland.
Dr Ronan Glynn, Acting Chief Medical Officer, has singled out six counties which have seen a big jump in new infections.
He said: “We have seen a significant number of cases in Dublin, Kildare, Tipperary, Limerick, Cork and Carlow over the past number of days. I would urge people everywhere to follow the public health advice and reduce mixing of households where at all possible.
"As we head into Autumn when people are more likely to have cold or ‘flu-like symptoms please do not adopt a wait and see approach.
"The greatest protection you can give your family and friends is to isolate as soon as you have any symptoms and contact your GP by phone.
"Remember, there should be no charge for either a consultation with your GP nor for a COVID-19 test should you require one.”
Of the new cases there were 93 in Dublin, 22 in Kildare, 10 in Tipperary, 9 in Cork, 8 in Carlow, 6 in Waterford, 6 in Offaly and the remaining 10 cases are in Galway, Kilkenny, Limerick, Louth and Roscommon.
There have now been a total of 28,363 infections in Ireland, while the death toll remains at 1,777.
Of the cases notified today:
- 83 are men / 81 are women
- 65% are under 45 years of age
- 80 are confirmed to be associated with outbreaks or are close contacts of a confirmed case
