All passengers arriving into Ireland must provide a pre-departure negative or not detected Covid-19 PCR test result taken within 72 hours prior to arrival from today.
Under the new rules signed off by Cabinet last week, passengers may be asked to present evidence of their test result before boarding their airplane or ferry.
Passengers could also be asked to produce this evidence to Immigration Officers or members of the gardaí on arrival into the country.
If they travel without a prior test result, passengers could be subject to a fine, or detention.
