Taoiseach Micheál Martin has said it is clear a second wave of Covid-19 is underway across Europe.
Mr Martin said the pandemic had become the dominant issue on the agenda at the meeting of the European Council on Friday.
"It is very, very clear that this second wave essentially is underway across Europe," he said.
Mr Martin added that a similar pattern was emerging across the European Union of younger people becoming infected first and then a higher incidence of the virus being recorded in older people.
Mr Martin said concerns were raised at the meeting over the health and economic impacts of Covid-19 and also "the duration over which this will continue".
He said it was useful to discuss the matter and compare shared experiences with his European colleagues.
"The story in Ireland is not unique," the Taoiseach said. "It's quite similar to the pattern across Europe."
He also said there were calls for increased co-ordination around colour codes and the distribution of vaccines.
It comes as one more person has died with Covid-19 in Ireland.
Another 470 infections were confirmed, the National Public Health Emergency Team said.
