In normal conditions there is always some discharge (leucorrhoea, fluor) in the vagina. It consists of cervical mucus, lactobacillus mass and regenerating epithelial cells. The amount of discharge varies depending on the phase of the menstrual cycle.Treatment should be directed at the most likely cause of the infection. It is usually possible to obtain a diagnosis of sufficient accuracy by gynaecological examination and basic laboratory tests.In vulvovaginitis, vaginitis is usually the dominant component and vagina is the site of the primary infection, but symptoms in the vulva/external genitalia are often also present.
