Ringworm Disease

Ringworm is a common fungal skin infection otherwise known as tinea. Ringworm most commonly affects the skin on the body (tinea corporis), the scalp (tinea capitis), the feet (tinea pedis, or athlete's foot), or the groin (tinea cruris, or jock itch).

No. Ringworm is not caused by a worm. It's a fungal infection that often forms a ring-shaped rash. It can have a red center (seen here) or normal skin tone inside the ring. Other rashes can look like ringworm, including spider bites, nummular eczema, and Lyme disease, a more serious infection that produces a bull's-eye shaped rash. These require different treatments, so it's important to consult a medical professional.

Certain fungi can help the body, but the dermatophyte types that cause ringworm irritate the skin instead. These fungi live off the dead tissues of your skin, hair, and nails. Dermatophytes thrive in warm, moist areas, such as the skin folds of the groin area or between the toes. You’re at greater risk of getting ringworm if you sweat excessively or have minor injuries to your skin, scalp, or nails.

There are several types of ringworm (tinea) that can affect different parts of the body. When fungus affects the skin of the body, it often produces itchy, red, raised, scaly patches that may blister and ooze. The patches often have sharply defined edges. They are often redder around the outside with normal skin tone in the center, creating the appearance of a ring. Your skin may also appear unusually dark or light.

Tinea pedis is an extremely common skin disorder, also known as athlete's foot. This fungal infection may cause scaling and inflammation in the toe webs, especially the one between the fourth and fifth toes. Other symptoms include itching, burning, redness, and stinging on the soles of the feet.

Ringworm of the bearded area of the face and neck, with swellings and marked crusting, sometimes causes the hair to break off. In the days when men went to the barber daily for a shave, tinea barbae was called barber's itch.

Ringworm may involve the hands, particularly the palms and the spaces between the fingers. It typically causes thickening (hyperkeratosis) of these areas, often on only one hand. Tinea manuum is a common companion of tinea pedis (ringworm of the feet).

Ringworm is an example of a zoonotic disease (transmitted from animals to humans). Cats are among the most commonly affected animals. If a cat has ringworm, a person in the house often gets the infection. Dogs, cows, goats, pigs, and horses can also spread ringworm to humans. People catch ringworm from touching the animals, or touching their bedding, grooming items, saddles, carpeting, etc.

Sometimes, the diagnosis of ringworm is obvious from its location and appearance. Otherwise, doctors can test skin scrapings for tinea fungus.

Ringworm can be treated with antifungal creams containing clotrimazole (Cruex, Lotrimin), miconazole (Desenex, Monistat-Derm), ketoconazole (Nizoral), and terbinafine (Lamisil). In cases of severe or resistant infections on the scalp or nails, doctors may prescribe oral medicines such as terbinafine, itraconazole (Sporanox), griseofulvin, fluconazole (Diflucan), ciclopirox, or naftifine.
