Tinea capitis

Alternative names:

fungal infection of the scalp; fungal scalp infection; infection - fungal (scalp); tinea of the scalp

Definition:

An infection of the scalp with mold-like fungi called dermatophytes.

Causes, incidence, and risk factors:

The body normally hosts a variety of microorganisms, including bacteria, mold-like fungi (dermatophytes) and yeast-like fungi (such as Candida). Some of these are useful to the body. Others may multiply rapidly and form infections. Fungal infections are caused by microscopic plants (fungi) that can live on the dead tissues of the hair, nails, and outer skin layers.

Tinea capitis is a skin disorder that affects children almost exclusively. It can be persistent and contagious, almost to the point of epidemic; however, it often disappears spontaneously at puberty.

The fungi that cause tinea infections thrive in warm, moist areas. Susceptibility to tinea infection is increased by poor hygiene, prolonged moist skin, and minor skin or scalp injuries.

Tinea infections are contagious and can be passed by direct contact or contact with items such as combs, hats, clothing, or similar surfaces. They can be transmitted from contact with pets that carry the fungus.
