Toenail fungus infection is a common nail infection that affects the toenails. It affects the fingernails less commonly. Its medical name for this is onychomycosis. Toenail fungus occurs when fungi get in between the toenail and the toenail bed or the tissue right under the toenail. Most of the time, this happens when fungi get through a crack or cut in the toe.
6What is the cause of toenail fungus?
Many types of fungi can cause nail infections. Most toenail fungus infections are caused by a group of fungi known as dermatophytes. These are difficult to see using the naked eye. These feed off keratin, the protein found in toenails and fingernails. It’s what keeps the nails hard.
