Athlete's foot (also known as tinea pedis) is a fungal infection of the skin that causes scaling, flaking, and itch of affected areas. It is caused by fungi in the genus Trichophyton and is typically transmitted in moist areas where people walk barefoot, such as at gyms and shower areas. Although the condition typically affects the feet, it can spread to other areas of the body, including the groin. Athlete's foot can be treated by a number of pharmaceutical and other treatments.
