Athlete’s foot is the name given to a common fungal infection that occurs on the feet virtually always starting between the toes then spreading over the feet. The infection is one of the group called tinea by physicians, and the full name tinea pedis, refers to a fungal infection and its location (pedis means “foot”). Other locations for tinea infection include the scalp (tinea capitis, or ringworm), the genitals (tinea cruris), the nails (tinea unguium), and the entire body (tinea corporis).
