The second degree of cleanliness is not serious, which is normal and indicates that there is no growth of pathogenic bacteria in the vagina. It is recommended to keep the vulva clean in daily life, change underwear regularly and pay attention to the hygiene during sex and menstruation. Since the vagina is relatively hidden and there is a bladder in front of it and a rectum behind it, there are many chances of infection. Once there is yellow vaginal discharge, itching of the vulva, odor of vaginal discharge, or extraordinarily high discharge, go to the hospital at any time for examination and treatment according to the pathogenic bacteria infected. In addition, women are advised to wear cotton underwear in their daily life and use cotton sanitary napkins when they have their period, because mesh sanitary napkins may cause poor local ventilation and cause pathogenic infections.
