The Department of Health has been notified of 1,456 new cases of Covid-19.
The number of people in intensive care units is 66, down seven since yesterday.
There are 261 people being treated for the virus, down 27 on yesterday.
Earlier, the Health Service Executive CEO Paul Reid said a hugely disproportionate number of unvaccinated patients are in intensive care with Covid-19.
He urged people who still haven't come forward for a vaccine yet to do so.
Thankfully the hospitalised #COVID19 patients are now down to 261 & falling. ICU cases are rising at 71, with a hugely disproportionate number of unvaccinated patients. It's never too late to be vaccinated & our committment stands,to never leave anyone behind. It works. @HSELive— Paul Reid (@paulreiddublin) September 18, 2021
In Northern Ireland, six further deaths have been reported in people who tested positive for Covid-19. A further 1,072 cases were also reported.
Meanwhile, due to increasing Covid figures, a temporary test centre has been set up this weekend in Drogheda, Co Louth. The clinic is not a walk-in centre - but can be booked online.
Separately, Minister for Further Education Simon Harris has said pop-up vaccination centres will open on many college campuses later this month.
Mr Harris said these centres will be in addition to the regular vaccination centres which already operate in some colleges for the general public.
"This is all about making it as easy as possible for every student and indeed staff member to avail of full vaccination and the protection that that provides," he said on Twitter this morning.
The minister said that more than 83% of people aged between 16-29 have already had their first dose of a Covid-19 vaccine while more than 79% have been fully vaccinated.
Mr Harris also said these pop-up vaccination centres will operate in addition to a plan to ensure vaccinations can be accessed through student GP services.
