Overview

Ringworm is a fungus infection of the skin. It is not caused by a worm or bug. Ringworm causes round patches of baldness or scaly skin on the scalp. Ringworm of the scalp is most common in children 3 to 9 years old.

Sometimes a blister-like rash appears on the face with ringworm of the scalp. This is an allergic reaction that usually clears when the ringworm is treated.

The fungus that causes ringworm of the scalp spreads from person to person. You can catch ringworm by sharing hats, combs, brushes, towels, telephones, or sports equipment. You can also get it by touching a person with ringworm. Once in a while, it can also spread from a dog or cat to a person.

Ringworm of the scalp is treated with pills. Ringworm may come back after treatment. Treating ringworm of the scalp can prevent scarring and permanent hair loss.

How can you care for your child at home?

• Have your child take medicines exactly as prescribed. Call your doctor if your child has any problems with a medicine.
• Ask your doctor if a special shampoo might help. Your doctor can let you know if and how often you can use one.
• To prevent spreading ringworm:
  • As soon as your child starts treatment, throw away combs and brushes your child uses and buy new ones. Do not let your child share hats, sport equipment, or other objects. Ringworm-causing fungus can live on objects, people, or animals for several months.
  • Wash your hands well after treating or touching your child's rash.
  • Wash your child's clothes, towels, and bed sheets in hot, soapy water.
