Ringworm of the body (tin ee uh COR por is) is an infection of the skin caused by a fungus (a plant which is too small to see). Ringworm is not caused by a worm. The infection starts as a rash with tiny red pimples. The pimples slowly spread and form a round or oval ring, typically ½ to 1 inch (12 to 25 mm) in size. The edges of the area are red, raised or scaly. After the ring has formed, the skin inside the rash may look pink or almost normal. The rash usually appears in only a few places on the skin but it may occur anywhere on the body and may itch. Ringworm rarely causes serious problems. Ringworm is contagious. It can spread to humans from puppies, kittens and pet rodents. It can also spread from people to people when someone touches the rash or handles something that has touched it. DiagnosisThe doctor will diagnose ringworm based on the child’s health history and by looking at the rash. A few scales from the infected area may be scraped and sent to the lab for more testing. TreatmentA single patch of ringworm can be treated with an over-the-counter antifungal cream. The cream will usually contain miconazole, ketoconazole or clotrimazole.
