Fungal Nail Infection, Fungus Infection on Nails

A form of microscopic plant, fungus can attach itself to a variety of surfaces. Fungal nail infections occur when these small plants take up residence in your nails' keratin. The best way to treat fungal infections is through prevention.

Fungus breeds in dark, damp, warm environments, so avoid walking barefoot in changing rooms or through mud. Furthermore, fungus loves dark, damp shoes and socks which means toenails are more frequently plagued than fingernails. If you should get a fungal infection, your doctor will prescribe an antifungal ointment or oral antifungal medication.

Fungal nail infections are particularly vexing since they must grow out with your nail. This means that even with care, an infection can take up to 7 months to cure. If left untreated, fungus-infested nails will become yellowed and deformed.
