Symptoms depend on the affected area of the body:

• Ringworm is a red skin rash that forms a ring around normal-looking skin. A worm doesn't cause it.
• Scalp ringworm causes itchy, red patches on your head. It can leave bald spots. It usually affects children.
• Athlete's foot causes itching, burning and cracked skin between your toes.
• Jock itch causes an itchy, burning rash in your groin area.
