Fungal infection

A fungal infection usually appears on the skin, as the organisms live on a protein called keratin. This protein makes up the nails, skin and hair. Symptoms of a fungal infection depend on the type of fungus that has caused the infection. Symptoms and appearance also depend on the part of the body infected.

Tinea

Tinea is a type of fungal infection of the hair, skin, or nails. Tinea usually begins as a small red area the size of a pea. Tinea is often called ringworm because it may look like tiny worms are under the skin.

Athlete’s foot

Athlete’s foot usually appears between the toes but can also affect toenails and the bottom or sides of the feet.

Jock itch

Jock itch is a fungal infection of the groin and upper thighs (girls and women can get it, too).

Candida

Candida is a yeast, similar to a fungus. It most often affects the skin around the nails or the soft, moist areas around body openings. Older girls and women may develop another form of candidal infection in and around the vagina. This is called a yeast infection.
