Ringworm of the body (tinea corporis) is a rash caused by a fungal infection. It’s usually a red, itchy, circular rash with clearer skin in the middle. Ringworm gets its name because of its appearance. No worm is involved.
Ringworm of the body is 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.
Mild ringworm often responds to antifungal medications that you apply to your skin. For more-severe infections, you may need to take antifungal pills for several weeks.
