Overview
Tinea capitis is a fungal infection of the scalp. It is also called ringworm of the scalp.

What are the symptoms of Tinea capitis?
Tinea capitis may involve only parts of the scalp, or all of it. Areas that are infected appear bald with small black dots, due to hair that has broken off.

Round, scaly areas of skin that can be red or swollen (inflamed) may be found, as well as pus-filled sores called kerions.

You may have a low-grade fever of around 100 - 101 Â°F or swollen lymph nodes in the neck.

There is usually itching of the scalp.

What causes Tinea capitis?
Fungi are a type of germ that can live on the dead tissue of the hair, nails, and outer skin layers. The body normally hosts a variety of fungi. Tinea capitis is caused by by mold-like fungi called dermatophytes.

The fungi that cause tinea infections do well in warm, moist areas. A tinea infection is more likely if you have:


 * Minor skin or scalp injuries
 * Poor hygiene
 * Wet skin for a long time (such as from sweating)

Who is at highest risk?
Tinea capitis or ringworm can spread easily to others. It most often affects children and goes away at puberty. However, it can occur at any age.

Tinea infections are contagious. You can catch tinea capitis if you come into direct contact with an area of ringworm on someone else's body, or if you touch items such as combs, hats, or clothing that have been used by someone with ringworm. The infection can also be spread by pets, particularly cats.

Diagnosis
The appearance of the scalp will make the health care provider suspect tinea capitis. A special lamp called aWood's lamp test can help diagnose a fungal scalp infection.

The health care provider may swab the area and send it for a culture. However it may take up to 3 weeks to get these results.

Rarely, a skin biopsy of the scalp will be done.

When to seek urgent medical care?
Call for an appointment with your health care provider if you have symptoms of tinea capitis. Home care remedies do not effectively treat tinea capitis.

Treatment options
The health care provider will prescribe a special medicine you take by mouth to treat ringworm in the scalp.

Griseofulvin, terbinafine, and itraconazole are used to treat this condition You take the medicine for 4 to 8 weeks

Keep the area clean. A medicated shampoo, such as one that contains ketoconazole or selenium sulfide, may slow or stop the spread of infection through the air. However, the shampoo alone cannot get rid of the ringworm.

Other family members and pets should be examined and treated, if necessary.


 * Other children in the home may want to use the shampoo 2 to 3 times a week for around 6 weeks.
 * Adults only need to wash with the shampoo if they have signs of tinea capitis or ringworm.

Once the shampoo has been started:


 * Wash towels in warm, soapy water and dry each time they are used by someone who is infected
 * Soak combs and brushes for 1 hour a day in a mixture of one-half bleach and one-half water. Do this for 3 days.

No one in the home should share combs, hairbrushes, hats, towels, pillowcases, or helmets with other people.
