According to Jena Sussex, MD, from the University of Southern California, the germiest places we should avoid touching at the airport start with security bins, the biggest offenders when it comes to the flu virus in airports. A study on BMC Infectious Diseases found that "plastic security screening trays appeared to pose the highest potential risk, and handling these is almost inevitable for all embarking passengers."
Take a few extra seconds to guard your immune system. Try to shake off the idea that you're inconveniencing the line — or just pull your bin to the side — it only takes a moment, and you've got every right to protect yourself from germs. Wipe it down with an anti-bacterial wipe, then place your items inside. Afterward, wash your hands thoroughly or use hand sanitizer if you're in a hurry.
