Mr Varadkar confirmed that he was tested on Tuesday and the result was negative.
In a statement, Mr Varadkar said: “Yesterday I was informed that I was a close contact of someone who tested positive for Covid 19. I was swabbed yesterday and the test has come back negative.
“In line with public health advice, I will be restricting my movements to home and outdoor exercise. There are no implications for anyone who has been in close contact with me. I am perfectly well and will be working from home.”
Minister for Finance Paschal Donohoe is also restricting his movements after close contact with a confirmed case of Covid-19.
Mr Donohoe's French counterpart Bruno Le Maire tested positive for the virus following a Eurogroup meeting in Germany on September 11th, which Mr Donohoe attended in his role as president of the group.
