Athlete's foot is a common fungal infection occurring in men and women of all ages. Unlike its name suggests, you do not have to be an athlete to get athlete's foot. The majority of cases are caused by a variety of fungi belonging to a group called dermatophytes, which thrive in closed, warm, moist environments. It is mildly contagious and can spread through direct contact with particles left on towels, shoes, or the floor. If you suspect you have athlete's foot, schedule an appointment with a physician at the Cleveland Foot & Ankle Clinic to develop a treatment plan.
