Passengers arriving from overseas will face a fine or jail if they fail to fill out a Covid-19 passenger locator form.

Anyone who fails to do so could be imprisoned for up to six months or face a fine of up to 2,500 euro. A further 17 people have died here from Covid-19 and 73 new cases have also been confirmed.
