Ringworm is a fungal infection of the skin. Despite its name, it has nothing at all to do with worms. The fungal infection may appear on the skin, nails, hands, feet, or scalp.

Ringworm is caused by microscopic skin fungi that live on the outer layer of the skin. You can get ringworm from direct skin-to-skin contact with infected people or pets. It is also transmitted by sharing hats and personal hair grooming items, and through contact with locker room floors, shower stalls, seats, or clothing used by an infected person.
