While numerous myths surround why travelers fall ill, recent studies suggest that the culprit might be closer than we think: the surfaces we touch rather than the air we breathe. Preventive medicine specialist, April Wilson, MD, MPH, FACPM, supports these findings and provides tips to prevent illness during holiday travel.
It’s a common misconception that the recycled air in airplanes is a breeding ground for viruses and bacteria. However, Wilson says, “The air quality inside airplanes is generally quite good due to advanced filtration systems. The real concern lies in the surfaces passengers come in contact with during their journey.”
An International Air Transport Association (IATA) study found that modern aircraft are equipped with High-Efficiency Particulate Air (HEPA) filters, which effectively remove more than 99% of airborne particles, including viruses. Therefore, the focus should shift from worrying about the air to paying attention to the surfaces being touched.
Wilson says research indicates that the transmission of infections on airplanes is often linked to the surfaces passengers encounter. Tray tables, armrests, and, seatbelt buckles can harbor germs for hours, if not days.
To prevent potential illnesses, she recommends adopting proactive measures such as regularly wiping personal space surfaces with disinfectant wipes. “Taking a few minutes to sanitize the immediate surroundings can significantly reduce the risk of contracting infections,” Wilson says.
