Symptoms of Ringworm

  • Often only on one side of the face or body
  • Mildly itchy

Cause

  • An infection of the skin caused by a fungus. It is not caused by a worm.
  • Can often be spread to humans from puppies or kittens that have it. Pet rodents also can carry it.
  • Rarely, can be spread human-to-human. It needs direct skin contact to be passed this way. An exception is that ringworm can occur often among wrestlers. This is because of close body contact during matches.
