Vaginitis is inflammation (redness) of the vagina. It can have different causes, including a yeast infection called Candida albicans, a type of fungus, which is one cause. It is very common with up to 75% of women having a vaginal yeast infection. Women of any age can get these infections. When Candida yeasts are in large numbers, they can cause symptoms. In most cases, Candida vaginitis is easily treated. A number of women have recurring yeast infections.
