Ringworm is a contagious skin infection that is caused by a fungus. Ringworm gets its name from the ring-like appearance the rash takes on, and is not caused by an actual worm. Symptoms of ringworm include a scale-like, flat rash that sometimes itches, and in later stages a raised ring appears around the initial rash. This border may not always be a clear circle and may sometimes look more like a relaxed rubber band or a handful of red bumps that form a circle. Ringworm is transferred via direct contact with an infected person, animal, object or sometimes soil. If you have a rash that does not improve or displays any of the characteristics of ringworm, make an appointment with your primary care provider. Ringworm needs to be treated with topical or oral antifungal medications that your doctor can prescribe.
