Causes, incidence, and risk factors
Tinea corporis is a common skin disorder among children. However, it may occur in people of all ages. It is caused by mold-like fungi called dermatophytes.
Fungi thrive in warm, moist areas. The following raise your risk for a fungal infection:
Long-term wetness of the skin (such as from sweating)
Minor skin and nail injuries
Tinea corporis can spread easily to other people. You can catch the condition if you come into direct contact with an area of ringworm on someone's body, or if you touch contaminated items such as:
Shower floors and walls
The fungi can also be spread by pets (cats are common carriers).
Symptoms may include
The rash begins as a small area of red, raised spots and pimples. The rash slowly becomes ring-shaped, with a red-colored, raised border and a clearer center. The border may look scaly.
The rash may occur on the arms, legs, face, or other exposed body areas.
Signs and tests
The health care provider can often diagnose tinea corporis by how the skin looks.
In some cases, the following tests may be done:
Keep the skin clean and dry.
You can buy antifungal cream without a prescription, or your health care provider may prescribe it.
Wash and dry the area first.
Apply the cream, beginning just outside the area of the rash and moving toward the center. Be sure to wash and dry your hands afterward.
Use the cream twice a day for 7 to 10 days.
Do not use a bandage over ringworm.
Creams that contain miconazole, clotrimazole, ketoconazole, terbenifine, or oxiconazole are often effective in controlling ringworm.
Once treatment has started, a child can return to school.
To prevent the infection from spreading:
Wash all towels in warm, soapy water and then dry them.
Use a new towel and washcloth every time.
Clean sinks, bathtubs, and bathroom floors well after using.
Wear clean clothes every day and do not share clothes
Your health care provider will prescribe medicine taken by mouth to treat ringworm that:
Is severe or covers a large area of your body
Passes deeper into the skin to the hair follicle, such as in a beard.
Antibiotics may be needed to treat secondary bacterial infections.
Infected pets should also be treated.
Ringworm usually responds to topical medications within 4 weeks. Severe or resistant cases usually respond quickly to antifungal medicines taken by mouth.
Complications Bacterial skin infections, cellulitis
Skin disorders such as pyoderma or dermatophytid
Spread of tinea to feet, scalp, groin, or nails
Whole-body (systemic) side effects of medications Calling your health care provider
Call for an appointment with your health care provider if ringworm does not improve with self-care.
