This condition is actually not a worm at all, but rather a fungus in the outermost layer of the skin that expands outward, often in a ring shape.  It is typically red, dry and scaly, and it may or may not be itchy.   Also known as tinea corporis, ringworm infections in different areas of the body are sometimes given their own name, including athlete’s foot (tinea pedis), jock itch (tinea cruris), scalp ringworm (tinea capitis) and others.   Although fungal infections may spread from person to person, and may spread from one area of your skin to another, they typically do not invade internally and do not get into the bloodstream.

Treatment for ringworm depends on the location of the eruption, and the extent.  It may be treated with creams or pills.  Your doctor will discuss the advantages and disadvantages of your treatment options with you before proceeding with your therapy.
