What is ringworm, & how is it treated?
“Ringworm” is the common name for the skin infection caused by a special group of fungi; it is not caused by a worm at all. The fungi feed upon the dead cells of skin and hair causing, in people, a classic round, red lesion with a ring of scale around the edges and normal recovering skin in the center. Because the ring of irritated, itchy skin looked like a worm, the infection was erroneously named. The fungi responsible are called “dermatophytes,” meaning “plants that live on the skin” thus the more correct term for ringworm is “dermatophytosis.” The characteristic “ring” appearance is primarily a human phenomenon. In animals, ringworm frequently looks like a dry, grey, scaly patch but can also mimic any other skin lesion and have any appearance.
