Fungal Nail Infections (cont.)
IN THIS ARTICLE
Health Tools help you make wise health decisions or take action to improve your health.
Fungal nail infections can be caused by three different types of fungus, alone or in combination.
Fungal infections are classified by where they begin and what they affect. Most fungal nail infections affect the skin under the nail (nail bed) and the nail itself (nail plate).
A condition called onycholysis, the separation of the nail from the skin beneath, can increase the risk of fungal nail infections.
You can get a fungal nail infection when you come in contact with the fungus and it begins to grow on or under your nail. Fungi grow best in warm, moist areas, such as the area around the toes. But you can have fungi on your skin without getting a nail infection. You have to be likely to get the infection (susceptible) for it to develop. If you are susceptible to fungal infections, they tend to return, even after successful treatment and especially if you do not take preventive steps.
It is not clear why some people are more susceptible to fungal infections than other people.
