Ireland has recorded 1,558 new cases of Covid-19.
As of 8am on Monday morning, there were 262 people fighting the deadly virus at hospitals nationwide.
Of these, 51 were in intensive care units.
Dr. Tony Holohan, Chief Medical Officer has said: “Though we have growing levels of vaccination across the population, there is now a very high level of disease circulating in the community. The Delta variant has enabled Covid-19 to regain a foothold in Ireland, which puts us all at risk as social contacts and mobility increase. We are closely monitoring the spread of the virus with some concern.
"Vaccines will help us turn the tide, but we are not there yet. We need to give vaccines the time and space to build up levels of protection across all demographics so that we can continue to progress the re-opening of all sectors of society and our economy.
"Please get vaccinated as soon as a vaccine is offered to you. It is also very important that people receive their second dose of vaccine as soon as you are called to do so. You will be fully protected one or two weeks after your second dose, depending on which vaccine you have received.
"I am asking people to be cautious and to closely follow public health advice over the coming weeks, in particular in the run-up to schools reopening in September.
"We all know what this means, and, more importantly, we know that by following the public health advice we can drive down the incidence of COVID-19 in our communities. If you have any symptoms that indicate that you may have COVID-19 like cough, fever, headache, sore throat and blocked or runny nose isolate and get a test immediately. Make plans to socialise safely and risk assess as you go, meet up with others outdoors if possible, try to meet up in small groups and avoid crowds. If you do not feel safe, then leave..
"Please continue to wear a mask where appropriate, wash your hands, manage your contacts and maintain your social distance."
The latest figures were confirmed by the National Public Health Emergency Team via the Department of Health.
Earlier this afternoon, it was confirmed that hundreds of Irish holidaymakers were forced to isolate as positive Covid tests were found on dozens of flights.
Niamh O’Beirne, the HSE's national lead for testing and tracing, said coronavirus cases have been identified on up to 30 flights a day in recent weeks.
Contact tracers with the health service have been working to follow up on holidaymakers who travelled on flights where a positive case was identified.
This includes tracking and tracing people sitting two rows in front, behind and to the side of the person with the virus.
This means as many as 500 people are impacted, Ms O'Beirne told RTE Radio One's Today programme.
Transmission of the virus on flights was "quite low", with the "most likely" scenario that people had contracted the virus before they boarded their flights back to Ireland, she said.
She explained that around 7.5% of coronavirus cases in Ireland recently can be linked to travel, and the majority of 110 to 120 outbreaks a week is linked to social gatherings and workplaces.
Most recent data gathered from the HSE on whether Irish people have travelled abroad within the past 14 days showed that "7.5% of cases would have travelled in the recent past", and this can range between 5 and 10%.
Elsewhere, Ireland's latest roadmap out of the pandemic is expected to be released towards the end of the month with big changes to restrictions.
It has already been established that Micheál Martin will announce a timetable for the final ending of all restrictions before the end of this month.
This is expected to signal the Government's official ending of the third pandemic lockdown and the special Cabinet subcommittee on Covid agreed that there will be a “roadmap for the easing or removal of the remaining restrictions” published within weeks.
