Candida Albican (Candida) is a type of yeast – this is one of the most common causes of nail fungal infection. It usually lives in your digestive tract, and you even find small amounts of the yeast throughout the body.

They are various kinds of fungi other than Candida throughout the body, but the same fungi that cause jock itch, athlete’s foot, and ringworm can cause nail fungal infection. The fungi thrive in warm and moist areas, and this kind of environment can make them naturally overpopulate. Therefore, the American Academy of Dermatology (AAD) mentions fungal infections are more common in toenails than fingernails due to the warm and moist environment in your shoes. Although those fungi sometimes live on your skin and don’t make any trouble, when you have a lot in one area, you might get infected.

You also may get nail infections when someone else who has a fungal infection has come in contact with you. If you go to a nail salon to get a manicure or pedicure done, make sure to ask how often they sanitize their tools and how they do it. Tools such as nail clippers can spread fungal infections from person to person if it is not disinfected.
