Vaginitis is a very common disease, which is characterized by an inflammation or infection of the vagina. Vaginitis can be further classified as inflammation of solely the vulva, which is called vulvitis, or inflammation of the vulva as well as inflammation of the rest of the vagina, which is called vulvovaginitis. The vulva can be defined as the external portions of the vagina, including the inner and outer lips (labia majora and labia minora), the vaginal opening and the area surrounding it (vestibule), the urinary opening, and the skin between the vagina and the anus (perineum). Vulvovaginitis is common in women of all ages, and is the leading gynecological disease diagnosed in girls who have not yet reached puberty. Although vulvovaginitis can cause irritation, itching, and a vaginal discharge, it can typically be treated with medication or a topical cream.
