It comes as Minister for Foreign Affairs Simon Coveney said if there is "a serious problem" with UK travellers coming through the Republic as a backdoor to avoid quarantine the Government will "sort it out".
Speaking on RTÉ's This Week, he said: "If that is being abused by UK citizens coming back from other parts of the world to try to take advantage of that issue, we will close that door by ensuring there is communication with airlines and the UK authorities to make sure they exactly know where people are coming from through an Irish airport."
He also said the UK authorities need to ensure that people landing at British airports are treated in a way that is consistent with public health advice.
He went onto say Ireland has "very similar quarantine" rules as the UK.
Mr Coveney said there is no resistance coming from the Irish Government in sharing data and information.
Adding that if there are data-sharing issues that need to be worked out, the Irish Government will talk with the UK authorities.
Minister Coveney also pointed out that if people are travelling through Ireland it is no different to Irish people travelling through the UK to get to other parts of the world.
He said the key issue is that those transiting through airports do not present a risk according to the World Health Organization.
Meanwhile, Chief Medical Officer Dr Tony Holohan appealed to people who feel unwell over the weekend with Covid-19 symptoms to contact their GP immediately.
Dr Holohan said that now was not the time to adopt a "wait and see" approach.
He said that people who feel unwell over a weekend often delay calling their GP but this wait and see approach should not be adopted at the moment and he urged people to seek medical advice at the earliest opportunity.
He also said people should not leave their houses if they have any cold or flu-like symptoms, in a bid to limit the spread of Covid-19.
Professor Philip Nolan of the National Public Health Emergency Team (NPHET) said the country is making steady progress in the fight against the disease after a very challenging surge.
He said if progress continues to be made, infections could be driven down to low numbers and the scene could be set for a phased, cautious, and controlled resumption of priority activities.
