To prevent ringworm of the skin:
- Keep your skin clean and dry. Change your socks and underwear at least once a day.
- Wear loose-fitting cotton clothing. Avoid tight underwear, pants, and panty hose.
- Always dry yourself completely after showers or baths. After drying your skin with a towel, allow your skin to air-dry before putting your clothes on. You can also use a hair dryer, set on a cool setting, to dry your skin.
- 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.
- Shower and shampoo thoroughly after any sport that requires skin-to-skin contact.
- If you have , put your socks on before your underwear so that fungi do not spread from your feet to your groin. Also, when toweling off after a shower or bath, dry your feet last.
- Take your pet to a veterinarian if it has patches of missing hair, which may be a sign of a fungal infection. Household pets can spread fungi that cause ringworm in people.
