From planes to trains to buses, germs manage to sneak their way on board and contaminate passengers. Sick people are likely to leave cold viruses on the objects they touch, like door handles, hand rails and seats. A Swiss study showed that the influenza virus can remain alive and ready to infect for up to 17 days. And don’t forget about food trays, seat backs and restrooms on airplanes. Researchers have found large numbers of bacteria on them, specifically E.coli.
Protect yourself: Wash your hands frequently, avoid people who are coughing and sneezing, drink plenty of water, and make sure you are well-rested pre- and post-trip.
