Ringworm is difficult to prevent. The fungus that causes ringworm is common and contagious even before signs and symptoms appear. However, you can help reduce the risk of ringworm by taking these steps:
* Educate yourself and others. Be aware of the risk of ringworm from infected persons or pets. Tell your children about ringworm, what to watch for and how to avoid the infection.
* Shampoo regularly. Be sure to wash your child's scalp regularly, especially after haircuts.
* Keep clean. Be sure your child washes his or her hands often to avoid the spread of infection. Keep common or shared areas clean, especially in schools, child care centers, gyms and locker rooms.
* Avoid infected animals. The infection often looks like a patch of skin where fur is missing. In some cases, though, you may not notice any signs of the disease. Ask your veterinarian to check your pets and domesticated animals for ringworm.
* Don't share personal items. Don't let others use your clothing, towels, hairbrushes or other personal items. Refrain from borrowing these items from others as well.
For a mild case of ringworm, you can apply an over-the-counter antifungal lotion, cream or ointment. Most fungal infections respond well to these topical agents, which include:
* Clotrimazole (Lotrimin, Mycelex)
* Miconazole (Micatin)
* Terbinafine (Lamisil)
Wash and dry the affected area. Then, apply a thin layer of the topical agent once or twice a day for at least two weeks, or according to package directions. If you don't see an improvement after four weeks, see your doctor. (MayoClinic)
Fungi thrive in warm, moist areas, such as locker rooms and swimming pools, and in skin folds. The fungi may be present without any symptoms. To prevent ringworm:
* Do not share clothing, sports equipment, towels, or sheets. If you think you have been exposed to ringworm, wash your clothes in hot water with fungus-killing (fungicidal) soap.
* Wear slippers or sandals in locker rooms, showers, and public bathing areas, especially during treatment.
* Shower and shampoo thoroughly after any sport that requires skin-to-skin contact.
* Wrestlers should regularly inspect the skin before practice, use protective bandages over infections while practicing or avoid competition until 1 week after symptoms resolve, and thoroughly disinfect gym pads and equipment.
* Wear loose-fitting cotton clothing. Change your socks and underwear at least once a day.
* Keep your skin clean and dry. Always dry yourself completely after showers or baths.
* If you have athlete's foot, put your socks on before your underwear so that fungi do not spread from your feet to your groin.
* Take your pet to the vet if it has patches of missing hair, which could be a sign of a fungal infection.
* Continue topical remedies for 2 to 4 weeks after symptoms have resolved.
* To prevent ringworm from returning after treatment, apply talcum or other drying powder to the affected area daily.
