The fungus that causes Ringworm of the body lives in humans, animals, and soil. The fungi that cause Ringworm of the foot and Ringworm of the nails live only in humans
What is the treatment for Ringworm?
Ringworm usually responds well to self-care within four weeks without having to see a doctor.
- Keep your skin clean and dry.
- Apply over-the-counter antifungal or drying powders, lotions, or creams. Those that contain miconazole, clotrimazole, or similar ingredients are often effective.
- Wash sheets and nightclothes every day while infected.
A severe or persistent infection may require treatment by a doctor. Antifungal pills may be given and are necessary if your hair is infected. Prescription antifungal skin medications, such as ketoconazole, are stronger than over-the-counter products and may be needed. Antibiotics may also be needed to treat related bacterial infections.
Infected pets also should be treated.
Ringworm can be treated with fungus-killing medicine. The medicine can be in taken in tablet or liquid form by mouth or as a cream applied directly to the affected area.
What complications can result from Ringworm?
Lack of or inadequate treatment can result in an infection that will not clear up.
Is Ringworm an emerging infection?
Although Ringworm is not tracked by health authorities, infections appear to be increasing steadily, especially among pre-school and school-age children. Early recognition and treatment are needed to slow the spread of infection and to prevent re-infection.
How can Ringworm be prevented?
Ringworm is difficult to prevent. The fungus is very common, and it is contagious even before symptoms appear.
Steps to prevent infection include the following:
- Educate the public, especially parents, about the risk of Ringworm from infected persons and pets.
- Keep common-use areas clean, especially in schools, day-care centers, gyms, and locker rooms. Disinfect sleeping mats and gym mats after each use.
- Do not share clothing, towels, hair brushes, or other personal items.
Infected persons should follow these steps to keep the infection from spreading:
- Complete treatment as instructed, even after symptoms disappear.
- Do not share towels, hats, clothing, or other personal items with others.
- Minimize close contact with others until treated.
- Make sure the person or animal that was the source of infection gets treated.
