Fungal nail infections are a common condition of toenails and fingernails, making them discolored, misshapen, thickened, and more likely to crack or break. This type of infection is more prevalent in toenails compared to fingernails. The technical name to use for a toenail infection is onychomycosis. It is common, especially among older adults. Medical experts said that toenail fungus affects 1 out of 10 adult people and 2 out of 10 people who are older than 70. Toenail fungal infection occurs when the fungus gets in between the toenail and the nail bed by way of a crack or cut in your toes.
6What are some causes of nail infection?
A toenail infection can be caused by more than one type of fungus. Most nail infections are caused by dermatophytes which is a type of mold. These are fungal microorganisms that can be too tiny to see using the naked eye. Dermatophytes feed off keratin, a protein found in the hair and nails. Nail infection may also be caused by yeast.
