A flight into Ireland that contained 13 people infected with the Coronavirus resulted in an outbreak of 59 cases of the virus. It happened during the summer according to a new EU report on air travel.
This group of 13 people, who we know had the virus, got on the plane after arriving from three different continents.
The youngest case was just one year old, while the oldest was 65.
Twelve of them were asymptomatic.
However details of where the plane came from and where it landed have been kept off the report.
We do know the flight was seven and a half hours long, had 49 passengers and 12 crew.
But some of those passengers had spent hours in the airport ahead of boarding.
When the aircraft touched down in Ireland those passengers went about their business.
Those thirteen went on to infect 46 others - which totalled 59 cases in six of the eight HSE regions.
Four people had to be hospitalised and one was admitted to intensive care.
