Ringworm is contagious. It spreads when you have skin-to-skin contact with a person or animal that has it. It can also spread when you share things like towels, clothing, or sports gear. You can also get ringworm by touching an infected dog or cat, although this form of ringworm is not common.
Animals can also be affected by ringworm and may transmit the condition to humans. In this case, ringworm is an example of a zoonotic disease, or a disease transmitted from animals to humans. Although catsare affected by ringworm more than dogs, dogs are also commonly affected. In animals, ringworm causes raised, circular areas that frequently are crusted over and associated with hair loss.
