By Mayo Clinic staffA vaginal yeast infection is a type of vaginitis — inflammation of the vagina — characterized by vaginal irritation, intense itchiness and vaginal discharge. A vaginal yeast infection affects your vagina and the tissues at the opening to your vagina (vulva).
Vaginal yeast infection — also called vaginal candidiasis — is very common. As many as 3 out of 4 women experience a yeast infection at some point in their lifetimes. Many women experience two or more yeast infections.
A vaginal yeast infection isn't considered a sexually transmitted infection, although the fungus that causes the condition can be spread through oral-genital contact. Simple treatment is usually effective, unless you have recurrent yeast infections — four or more in a single year. In that case, you may need a longer course of therapy and a maintenance plan.
