Causes
Tinea corporis (often called ringworm of the body) is a common skin disorder, especially 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
Poor hygiene
Tinea corporis is contagious. You can catch the condition if you come into direct contact with someone who is infected, or if you touch contaminated items such as:
Clothing
Combs
Pool surfaces
Shower floors and walls
The fungi can also be spread by pets (cats are common carriers).
Symptoms
Symptoms include itching and a ring-shaped, red-colored skin rash. The rash may occur on the arms, legs, face, or other exposed body areas. The border of the rash lesions look scaly.
Exams and Tests
The primary diagnosis is based on how the skin looks.
Keep the skin clean and dry. Over-the-counter antifungal creams, such as those that contain miconazole, clotrimazole, or similar ingredients, are often effective in controlling ringworm.
Severe or chronic infection may need further treatment by your health care provider.
Oral antifungal medications may be used for severe, widespread fungal infections, or an infection that has spread deeper into the skin to the hair follicle. Stronger, prescription topical antifungal medications, such as ketoconazole may be needed. Antibiotics may be needed to treat secondary bacterial infections.
Infected pets should also be treated.
Outlook (Prognosis)
Ringworm usually responds to topical medications within 4 weeks. Severe or resistant cases usually respond quickly to antifungal medicines taken by mouth.
Call for an appointment with your health care provider if ringworm does not improve with self-care.
Prevention
Good general hygiene helps prevent ringworm infections. Avoid contact with infected pets as much as possible.
Clean and dry clothing and household items, such as combs and bathroom surfaces, before you reuse them or another person uses them to prevent the spread of infection. Wash your hands thoroughly after having contact with any fungal infection, including when treating the infection.
