On the contrary, the study says, of the 42 samples taken from toilet lids, flush buttons and door locks, there were zero samples where scientists detected the presence of a cold virus.
The security trays are handled by virtually everyone who makes their way through an airport - not to mention their belongings, so it's no surprise that they play host to the greatest number of viruses.
Among 10 samples with evidence of a respiratory virus, rhinovirus, coronavirus and adenovirus occurred in four, three and one surface samples respectively, whilst adenovirus and influenza A were both found in one of the four air samples taken at security.
The various surfaces were swabbed at Helsinki-Vantaa airport at peak-time as part of a scientific investigation carried out by experts from the University of Nottingham and the Finnish National Institute for Health and Welfare during the winter of 2016.

The study was carried out by the University of Nottingham and the Finnish National Institute for Health and Welfare.
Such trays are also rarely disinfected, with their hard surfaces allowing viruses to survive for up to a day.
'The new findings support preparedness planning for controlling the spread of serious infectious diseases in airports.
"Although this would not eliminate all viruses on hands, (e.g. alcohol gels have been found to be less effective than hand-washing for rhinovirus), it is effective for many viruses, including influenza", they added.
Your best bet? Wash your hands as much as possible and keep the trusty hand sanitizer on standby.
