A yeast infection is caused by candida (say: KAN-dih-duh), a common fungus that is found on everyone's body. When babies get diaper rash, it may be a yeast infection. Kids also can get yeast infections, usually in warm, moist parts of their bodies including under their arms, in their mouths, or in the groin area. Girls can get it in their vaginas.
Yeast infections may make white spots in the mouth or cause a red rash, pain, or itching. Kids with yeast infections can use a cream or take medicine to feel better.
