Prevent future occurrences. There are many situations that make you more at risk for infection. You are at a higher risk if you are older, have diabetes, have an impaired immune system, or have poor circulation. If you are at high risk, you should take extra care to prevent infection. Preventative measures include wearing shoes or sandals when you are at damp public areas such as swimming pools or gyms, keeping your toenails clipped and clean, making sure your feet are dry, and drying your feet after you shower.
Topical treatment (polish or cream) isn’t likely to get rid of a fungal nail infection. Treatment with tablets is considerably more effective and takes less time. But some people can’t take tablets because of the very rare, yet serious risks. How you feel about the pros and cons of the different treatment options is a personal matter. You can also discuss the options with your doctor.

Healing time depends on the type of treatment used. Prevention of a new infection is important. Orthopaedic foot and ankle specialists recommend good foot hygiene with frequent changing of stockings and rotating pairs of shoes to allow them to completely dry between uses. Also, avoid going barefoot in locker rooms and around swimming pools. If you have a pedicure, make sure the nail salon uses sterilized instruments.
Nail-bed fungus is also called onychomycosis. It can affect anyone regardless of age, gender and hygiene and is spread by direct contact with skin or with infected surfaces. Common places you may be exposed to fungus are at nail salons, as well as showers at hotels, pools, nail salons, and gyms where you go barefoot. Housemates and family members with a fungal infection may also spread their condition.
