Athlete's foot is a very common skin condition that affects the sole of the foot and the skin between the toes, it can also spread to other parts of the body including the groin (ouch). It manifests itself as a scaly, red, itchy rash and occasionally may be weepy with emissions. It affects the feet of everyone, athletes and non-athletes alike. Although it is usually linked to a fungal infection, other causes may be comparable without professional medical testing. It can be quite nasty and should be avoided where possible.
The medical name for athlete's foot caused by a fungus is tinea pedis. There are a variety of fungi that cause athlete's foot, and these can be contracted in many locations, including gyms, locker rooms, swimming pools, pedicure salons and from contaminated clothing. The fungi can also be spread directly from person to person by contact. Most people acquire fungus on the feet from walking barefoot in areas where someone else with athlete's foot has walked. Some people are simply more prone to this condition while others seem relatively resistant to it. Another colorful name for this condition is "jungle rot," often used by members of the armed services serving in tropical climates.
Without the proper environment (warmth and moisture), the fungus may not easily infect the skin. Up to 70% of the population may develop athlete's foot at some time. An infection by athlete's foot fungi does not confer any resistance to subsequent infections.
