Ringworm (tinea corporis)

What is ringworm (tinea corporis)?

Ringworm (tinea corporis) is a fungal infection of the skin. It causes a red or silver scaly rash, which has the appearance of rings. Despite what its name might suggest, ringworm is not caused by worms – it gets its name from its circular appearance.

It is a fairly common condition, affecting between 10 and 20% of people during their lifetime. It usually appears on the arms or legs but can affect the scalp, groin, feet and nails. It is a fungus that likes moist, warm conditions and is easily spread via contact with pets, infected surfaces or direct contact. (See Causes)

In most cases, ringworm is effectively treated with an antifungal cream or ointment (See Treatments).
