Minister for Finance Paschal Donohoe is restricting his movements after the French finance minister tested positive for Covid-19.
Bruno Le Maire received his results on Friday evening and confirmed his positive result on Twitter.
“I tested positive for Covid-19 this evening,” Mr Le Maire said, adding that he would remain at home for seven days.
“I immediately followed the health measures brought in by the government by self-isolating at home.”
Mr Le Maire was in contact with Paschal Donohoe at a Eurogroup meeting in Germany on September 11 when the group had met to discuss Brexit.
Minister Donohoe was already working remotely, as he had returned from a country that was not on the green list at the time.
He will remain away from day-to-day in-person contact until Saturday.
Earlier today, the European Union said it has postponed its summit for a week because EU Council President Charles Michel has gone into quarantine after a close collaborator was diagnosed with Covid-19.
