The most germ-filled spot at the airport may not be where you think.
Researchers say those airport plastic trays are the biggest culprit for spreading germs in airports.
The team monitored germ levels on a variety of surfaces at a Finnish airport during the Winter of 2016. They found virus germs on ten percent of all the surfaces they tested.
Other germ hotspots were payment terminals, staircase rails, passport checking counters, children's play areas and in the air.
The most common germs found were rhinovirus, which is the cause of the common cold, and influenza.
The swabs did not detect any respiratory viruses on toilet surfaces.
Study authors say their work supports the case for improved public awareness on how germs spread.
Their work was recently published in the journal "BMC Infectious Diseases."
