The Department of Health has been notified of one further death of a person with Covid-19 and three additional confirmed cases.
Yesterday, Chief Medical Officer Dr Tony Holohan said the number of new cases of Covid-19 in younger people was now a real concern and a worrying trend.
Dr Holohan said that of the 23 new cases reported yesterday, ten - or 43% - were in people aged under 35. A further eight cases were in people aged between 35-54.
He said this was now "a real concern and a worrying trend" at a time, he said, when many people were reconnecting with loved ones, and may be gathering in larger groups.
