Athlete’s Foot

Athlete’s foot is a skin disease caused by a fungus, usually occurring between the toes.

The fungus most commonly attacks the feet because shoes create a warm, dark, and humid environment which encourages fungus growth.

The warmth and dampness of areas around swimming pools, showers, and locker rooms are also breeding grounds for fungi. Because the infection was common among athletes who used these facilities frequently, the term “athlete’s foot” became popular.

Not all fungus conditions are athlete’s foot. Other conditions, such as disturbances of the sweat mechanism, reaction to dyes or adhesives in shoes, eczema, and psoriasis, may mimic athlete’s foot.

Symptoms

The signs of athlete’s foot, singly or combined, are dry skin, itching, scaling, inflammation, and blisters. Blisters often lead to cracking of the skin. When blisters break, small raw areas of tissue are exposed, causing pain and swelling. Itching and burning may increase as the infection spreads.

Athlete’s foot may spread to the soles of the feet and to the toenails. It can be spread to other parts of the body, notably the groin and underarms, by those who scratch the infection and then touch themselves elsewhere. The organisms causing athlete’s foot may persist for long periods. Consequently, the infection may be spread by contaminated bed sheets or clothing to other parts of the body.
