Tony Holohan admitted to hospital after feeling unwell during coronavirus briefing

Chief Medical Officer Tony Holohan has been admitted to St James's Hospital for tests having complained about feeling unwell on Tuesday night.

It is understood the health complaint is unrelated to the Covid-19 outbreak, and thus social isolation protocols might not be necessary. Dr Holohan is expected to be released from hospital tomorrow.

The deputy chief medical officer Dr Ronan Glynn will substitute for Dr Holohan until his recovery which is expected by the end of this this week.

At the daily briefing on the Coronavirus pandemic at the Department of Health on Tuesday evening, Dr Holohan complained about feeling unwell about halfway through his contribution.
