Flying during flu season sounds like an easy way to come back home with a nasty, unwanted souvenir from your travels. But according to a new study published in the Proceedings of the National Academy of Sciences, it’s unlikely that you’ll catch the flu on your next flight.
Because the flu typically is transmitted through the air via small respiratory droplets from an infected person or from something an infected person has touched, whether you use the airplane lavatory and how well you wash your hands are all key factors in whether you end up catching the flu on your next flight.
‘Sneeze into your elbow, use good hand hygiene, and turn on your air vent. That will send the droplets straight to the floor,’ Vicki Stover Hertzberg, the study’s lead author and professor of nursing at Emory University, told The New York Times.’
But where you sit also matters a lot.
Using data collected from 1,540 passengers and 41 crew members from five different round-trip flights between Atlanta and the West Coast, researchers found that people sitting in aisle seats had contact with 64 other people on average, while those in the middle seat had 58 and the window seat only had 12. They also found that those seated in the middle of the cabin had more contact with other people than those with seats in the front or back.
Using this information, the research team set up 1,000 flight simulations using the estimate of one meter as the distance required to transmit the flu disease directly to another passenger on a plane. In the first scenario, the passenger in seat 14C in the middle of the plane had the flu, while in a second situation a crew member was infected with the virus.
