One flight into Ireland sparked 59 Covid cases in six HSE regions - study 

The study also highlights how the flight into Ireland was just one link in a broader international chain of air travel.

Fifty-nine laboratory-confirmed cases of Covid-19 from six of the eight different health regions were linked to just one international flight into Ireland last summer - and the plane was just 17% full and some passengers wore masks.

The case is included in a newly published issue of Eurosurveillance, a journal on infectious disease surveillance, epideomiolog, prevention and control.
