What is ringworm?

  • Ringworm is a common infection of the skin and nails that is caused by fungus. The infection is called “ringworm” because it can cause an itchy, red, circular rash. Ringworm is also called “tinea” or “dermatophytosis.” The different types of ringworm are usually named for the location of the infection on the body.
    • The fungi that cause ringworm can live on skin and in the environment. There are three main ways that ringworm can spread:
    • From a person who has ringworm.
    • From an animal that has ringworm.
    • From the environment.
