Infections are always part of everyday living. Candidias is is brought about by an overpopulation of a certain type of fungus in virtually any area of your body. This is considered as the most common type of yeast infection that proliferates in moist and warm body areas like the vagina, oral cavity, skin (lower abdomen, under the breast), underarms, and nailbed. Vaginal candidiasis can be resistant to some treatments and nailbed yeast infections take longer to treat. This type of infection may be considered as a sign or symptom of leukemia, AIDS, or diabetes.
