Nail fungus infections are a common medical concern that can affect many types of nails. This type of infection often affects toenails. These are usually caused by the growth of fungal spores that often appear between toenails and the skin found under the nail bed. The spores thrive because of the skin or the keratin found in the nail. This kind of fungi also causes the spread of the athlete’s foot, an infection of the skin in between the toes. The infection may spread to the toenails. It may also be caused by other types of fungi most often yeasts which tend to invade damaged nails due to easy access.
