The Department of Health has been notified of 46 additional cases of Covid-19 over the past day, with no new deaths recorded.
The death toll remains at 1,763. There have now been a total of 26,208 confirmed cases of coronavirus in Ireland.
Of the cases notified today, 27 are men and 19 are women, while 85% are under 45 years of age.
Thirty-two are associated with outbreaks or are close contacts of a confirmed case, while five cases have been identified as community transmission.
Fifteen cases are located in Kildare, eight in Laois, seven in Clare, five in Offaly and the remaining 11 are spread across nine other counties.
Acting Chief Medical Officer Dr Ronan Glynn said: "The vast majority of young people in Ireland have followed public health advice and have made very significant sacrifices to protect themselves and others.
"People of all ages will occasionally slip up as they learn to live safely with this virus.
"We should not seek to attribute blame, but rather continue to encourage one another to build on and sustain the great efforts that we have all made to date.
"We continue to urge everyone to observe the safe behaviours that we recommend such as physical distancing, washing hands regularly, wearing a face covering where appropriate, avoiding crowds and doing all we can to protect each other.
"NPHET continues to monitor the evolving situation very closely and will meet tomorrow."
Dr Glynn's remarks came after Clare County Council called for "responsible behaviour" after videos were posted to social media showing crowds of young people in Kilkee on Saturday night.
Minister for Health Stephen Donnelly said public health officials were watching the rising case numbers carefully and were concerned.
But he said the good news was that, while the number of cases had gone up, the vast majority of them were identified clusters.
The minister said the number of community transmissions remained at around one in five. Community transmission was what concerned public health officials the most and was being watched very carefully.
He refused to be drawn on what the rise in cases could mean for the reopening of pubs or the increasing of limits for indoor and outdoor gatherings, which were to be part of Phase 4 of the reopening of the economy on 10 August.
Mr Donnelly said NPHET would meet tomorrow morning and he would be advised by them. It would then be a matter for Government to discuss the advice and decide what to do .
He said they were "beefing up" measures relating to travel, including making the passenger locator form electronic and having a larger public health presence at airports as well as randomised testing.
But he said the message remained the same - Irish people were being asked to holiday at home and not to holiday abroad. That went for all countries he said, including green list countries.
Earlier, an Assistant Professor of Virology at Trinity College Dublin warned that if we are too cautious in re-introducing measures to reduce transmission of Covid-19, cases will begin to creep up again.
Speaking on RTÉ's Morning Ireland, Dr Kim Roberts said pubs and nightclubs are risky environments and added that reopening pubs that do not serve food and nightclubs is, she said, a very risky decision.
At the moment, she said, our numbers are still looking "very, very good" but it is worth looking ahead and trying to limit as much transmission as possible so the numbers do not increase over the next few weeks.
Dr Roberts warned community transmission is usually the tip of the iceberg and over a few weeks, numbers could increase dramatically.
She said she did not believe it would be necessary to return to a lockdown scenario because we are better educated on how to reduce the chains of transmission.
Dr Roberts said that clusters of transmission in factories can "looking quite alarming" but those outbreaks can be contained if good public health measures are introduced once a cluster is identified.
In Northern Ireland, the Department of Health has reported 40 new cases over the last three days, bringing the total number of cases there to 5,988, no one has died from Covid-19 there in the last 21 days.
Meanwhile, the incoming President of the Vintners' Federation of Ireland (VFI) said pubs that do not serve food are hopeful they will reopen on 10 August.
Paul Moynihan, who owns Moynihan's Bar in Donard West, Wicklow, said he believes that pubs can reopen safely if the guidelines are followed.
He said the local pub is very important in rural communities, like his own.
