Dublin Airport has insisted it is not "business as usual" at the airport during the current lockdown.
Some members of the public have been critical of the fact flights continue to land at the airport and no screening of passengers is being carried out.
However, it has said that Easter Monday saw less than 1% of the amount of passengers that it would normally have on that day in any other year.
And the airport has reminded the public that its current travel and health policies are based on expert guidance from the World Health Organisation, the HSE and the European Centre for Disease Prevention and Control.
In a Twitter thread, it said: "We had fewer than 900 arriving and departing passengers yesterday. On a normal Easter Monday we’d have more than 100,000 pax.
"That’s not business as usual. The T1 baggage hall, arrivals area and the exit road all looked very unusual."
The Government allows certain "essential businesses" to stay open during the Covid-19 lockdown - this includes airports.
Dublin Airport said: "We’re open because Irish Govt policy is that we’re open as an essential business to allow for the operation of vital cargo flights, such as medical supplies, and the repatriation of Irish citizens.
"Many passenger flights transport cargo in their belly holds."
It added: "As we’ve said before, Ireland’s travel & health policies in relation to #COVID19 are decided by the State, based on expert health advice from @hpscireland / @hselive.
"HSE isn’t screening, as it says entry screening doesn't work and isn’t recommended by @WHO or by @ECDC_EU."
All passengers arriving to the airport in recent weeks have been informed by HSE staff that they must restrict their movements for 14 days.
The final tweets of the thread said: "HSE staff based at the airport have informed all arriving passengers for several weeks that they need to restrict their movements for 14 days.
"The Irish Govt’s general movement restrictions also apply i.e. people need to stay at home.
"At all times since the outbreak of this public health crisis @DublinAirport has followed the health & travel guidelines that have been set out by the Irish State.
"Like other airports throughout the world, we adhere to policies set by our respective national governments."
