A nail fungal infection appears when a fungus attacks a toenail, fingernail, nail bed, or the skin under the nail. Fungi can attack the nails through small cuts in the skin surrounding the nail or through the space between the nail and nail bed. If the person is healthy, nail fungus infection won’t be a serious concern. This can become a problem when you suffer from diabetes or have a weakened immune system.
Molds, yeasts, and various types of fungi may cause nail fungal infections. The most common cause of this is a group of fungi known as dermatophytes. Fungi can easily spread in a moist and warm environment. You can easily get it when you are fond of walking barefoot in public pools and showers and sharing personal items like towels and nail clippers.
