RTÉ broadcaster Claire Byrne has revealed she has been diagnosed with Covid-19 but is over the worst of the virus.
Staff at RTÉ were informed by management on Saturday that a case had been confirmed at the station.
In a statement to her colleagues this afternoon, Ms Byrne said she had tested positive for Covid-19.
"I made the decision that I wanted you all to know this at the earliest opportunity. The HSE contact tracing system worked with me over the weekend.
"I am well now and through the peak of the condition and I want to thank everyone who has been in touch with me to express support and in particular, those in RTÉ who spent their weekend dealing with issues that arose as a result of my diagnosis."
She said she was getting better and was working with Medmark and her own GP who will assess when it is safe for her to return to work.
Meanwhile, Tánaiste Simon Coveney has been tested for Covid-19 but has been assured he has not contracted the virus.
Mr Coveney was tested after the HSE alerted him that he had been in direct contact with someone who had tested positive for the virus.
“Like thousands of people across the country, I was contacted in recent days by a member of the HSE contact-tracing team to say I had been in close contact with a person who has tested positive for Covid-19," Mr Coveney said.
"I followed all protocol and was tested. The result is negative for Covid 19. I would like to sincerely thank the HSE team for their professionalism and courtesy.
"Testing is going to be a reality for tens of thousands of people and it is vitally important that we all follow HSE direction in the interest of public health.”
It is understood Mr Coveney is the first member of cabinet to be tested.
However Housing Minister Eoghan Murphy has been in self-isolation after visiting family abroad.
