A further 1,377 Covid-19 cases have been confirmed in Ireland in the last 24 hours.
The Department of Health announced this afternoon there are now 78 in hospital with 22 of those in ICU.
It comes as the Taoiseach warned that cases will continue to rise amid the Delta wave.
Speaking to reporters in Cork, Mr Martin said: "The situation is serious in regards to Delta and all of us have to be vigilant in terms of our individual behaviours because this is a further twist in the road of Covid-19 and there will be high volumes of case numbers, which will continue to grow.
"We're going to keep a very close eye on the hospitalisations that results from that and the illness that results from that.
"We want to prevent people from getting Covid, so it's important people take it seriously from that point of view.
"Quite a lot of cases develop into Long Covid or complications which we do not want and do not need."
