Some foot fungal infections are very contagious and spread easily from person-to-person contact and contaminated surfaces; they can also migrate to other parts of the body. There are several over-the-counter medicated foot powders, creams, and sprays available to treat athlete’s foot; these should be used at the recommendation of a healthcare professional or doctor, as different fungi require different treatments. A doctor can prescribe topical or oral medications to treat severe cases.
Fungal infections can be prevented by the following suggestions:
- Wash and dry feet thoroughly, taking extra care to dry between the toes.
- Use powder to keep the feet dry.
- Keep socks and footwear clean and dry; socks can be changed several times daily.
- Wear footwear made of breathable materials that allow air to circulate around the feet; constricting footwear, stockings, and socks can trap moisture and perspiration on the feet.
- Never share socks or footwear.
- Do not walk barefoot in public areas such as showers, pools, and locker rooms; instead, wear plastic flip-flops, slides, or shower shoes.
Sanitize nail clippers, nail files, and pedicure instruments; never share them with others.
Avoid injuring the toenails and nail beds, which can eventually develop into an infection.
