Ringworm of the body is a fungal infection that develops on the top layer of your skin. It's characterized by a red circular rash with clearer skin in the middle. It may or may not itch. Ringworm gets its name because of its appearance. There is no actual worm involved.
Also called tinea corporis, ringworm of the body is closely related to athlete's foot (tinea pedis), jock itch (tinea cruris) and ringworm of the scalp (tinea capitis). Ringworm often spreads by direct skin-to-skin contact with an infected person or animal.
Antifungal medications are used to treat ringworm. Mild ringworm often responds to antifungal products that you apply to your skin. For more-severe infections, you may need to take antifungal pills for several weeks.
