Candida albicans is the most common type of yeast infection-related fungus, and naturally occurs in many part of our bodies. For the most part, it’s harmless.

Common symptoms of a yeast infection include burning, itching, painful urination, inflammation, pain during sex, and a thick, white discharge.
