A couple of weeks ago when I was traveling to Philadelphia to a wound care conference in the City of Brotherly Love, I got to thinking about what was taking place in the security line at the airport. Of course, as required, everyone was taking off their shoes to go through security. In many cases, as they walked barefoot, through the inspection line, they were exposing their feet to a variety of invaders: bacteria, viruses and fungi, any of which could penetrate a small break in the skin to cause some form of infection.
I began to think how dangerous that practice might be as thousands of travelers walk through these lines each day. Warts are caused by viruses and are pesky to eradicate and common in children but still can be found in adults and athlete's foot, a common fungal infection of the skin can be easily acquired by simple contact by the fungal spore found in the airport carpeting. Why take these invaders on a ride to your vacation destination? Take an extra precaution and wear socks through that line even if it is only to remove them to put your sandals back on.
