Ringworm is called such because it generally curves in a circle on the skin. This circular rash looks somewhat like a worm. However, ringworm is not a worm but rather a fungal infection. Ringworm is caused by parasitical microorganisms which begin to grow on the body. The fungus similar to mold live off of the body’s skin cells. It is usually apparent on the surface of the skin and most of the time located on the trunk or arms. It can also appear on the feet, then called athlete’s foot, or the scalp.
