Fungal infections of the nails are common. The fungus grows in the nail bed, where the nail meets the skin. The fungus grows slowly and does not spread to internal organs. Fungal infections are not commonly contagious or spread easily between people.

You might feel that you are the only one who has nail fungus, but you probably did not know that about 30 million people in the United States have the same problem that you do.

How do I tell if I have nail fungus?

• Look at your toes, because nail fungus is more common on your toes than on your fingers.
  
• Are your nails dark? If so, this may be a sign that you have a fungal infection.
  
• You might see a substance that is yellow, green, white or black under the nail.

Why do I get nail fungus?

• Moisture on your feet causes the fungus to grow, so it is best to keep your feet dry.
  
• This means not sleeping in socks!

How do I get rid of it?

• If keeping your feet dry does not make the fungus go away, ask your parents if you can see a doctor.
  
• The doctor can give you medicine or lotion to help the problem go away.
