Ringworm (Tinea Corporis)

Ringworm is a fungus infection of the skin. It is often transferred to people from puppies or kittens who have ringworm.

If your child has ringworm, your child will have a ring-shaped pink patch on the skin. The patch will:

• usually be 1/2 to 1 inch in size with a scaly, raised border and clear centre
• get slowly bigger
• be mildly itchy

How long does it last?

How can you take care of your child?

• Antifungal cream

  Buy Tinactin, Micatin, or Lotrimin cream at your pharmacy. You won't need a prescription. Apply the cream twice a day to the rash and 1 inch beyond its borders. Continue this treatment for 1 week after the ringworm patch is smooth and seems to be gone. Successful treatment often takes 3 to 4 weeks. Encourage your child to avoid scratching the area.

• Contagiousness

  Ringworm of the skin is mildly contagious. It requires direct skin-to-skin contact. The type acquired from pets is not transmitted from human to human, only from animal to human. After 48 hours of treatment, ringworm is not contagious at all. Your child doesn't have to miss any school or day care.

• Treatment of pets

  Kittens and puppies with ringworm usually do not itch and may not have any rash. Pets with a skin rash or sores should be examined by a veterinarian. Also have your child avoid close contact with the animal until he is treated. Natural immunity develops in animals after 4 months even without treatment. Call your veterinarian for other questions.

Call during office hours if:

• the ringworm continues to spread after 1 week of treatment
• the rash has not cleared up in 4 weeks
• you have other concerns or questions
