A further six people with Covid-19 have died in the Republic, while there have been 23 confirmed new cases.
The National Public Health Emergency Team says it brings the total death toll linked to the virus to 1,734, while the total number of confirmed cases stands at 25,437.
Chief Medical Officer Dr Tony Holohan says "high levels of compliance to public health advice to date has enabled further reopening of economic and social life".
But in a statement this evening he said there "is now a real concern and a worrying trend at a time when many people are reconnecting with friends and loved ones and may be gathering in larger groups".
And he said “In recent days, for example, some cases have had large numbers of close contacts that have required testing and self-isolation for 14 days.
However he's warned of the 23 new cases reported today 10, or 43 per cent, were under the age of 35 while 35 per cent were between 35 and 54.
