Candidiasis (kan-di-DYE-uh-sis) is a fungal infection caused by an overgrowth of
the common yeast candida, which is found on everyone's body.
More to Know
Candidiasis in newborns usually appears as diaper rash. But babies also can develop
it in the mouth or throat (called oral
thrush, or oropharyngeal candidiasis). This very common infection causes cracks
in the corners of the mouth and white patches on the tongue, palate, lips, and insides
of the cheeks. Often, these babies picked up the fungus during breastfeeding
or from their mother's vagina during delivery.
Candidiasis in the vagina (vulvovaginal candidiasis) is commonly called a yeast
infection. Vaginal yeast infections can cause pain, itching, redness, a thick
white vaginal discharge, pain during urination, and sometimes whitish patches on the
skin of the vaginal area. Yeast infections can happen to any girl, and are not considered
sexually transmitted infections.
Keep in Mind
Thrush in babies is treated with liquid antifungal medicine. Thorough cleaning
of all bottle-feeding supplies can help prevent thrush in formula-fed infants. A breastfeeding
mom whose nipples are red and sore might be passing the infection back and forth with
her baby; in that case, a doctor might recommend antifungal medications.
In most cases, vaginal yeast infections can be prevented by keeping the vaginal
area clean and dry. Doctors typically treat them with prescription medication taken
by mouth or a vaginal cream, tablet, or suppository; these will clear up the symptoms
in a few days and the infection within a week.
