BV positive means that the woman has bacterial vaginitis, which is not necessarily transmitted by the male partner and does not mean that there is a sexually transmitted disease, but may be related to women not paying attention to private hygiene, poor female resistance, or women and men not paying attention to hygiene during sex. If a woman is found to be positive for BV, if she does not intend to have children in the near future, she can douche her vagina with cleanser and use metronidazole vaginal suppositories to plug her vagina for a week, while taking one oral metronidazole tablet in the morning and one in the evening for a week. You should pay attention to the hygiene of your private parts, change your underwear every day, wash your vulva, wear cotton underwear, not tight pants, and preferably not chemical fiber underwear, but loose pants. In addition, we should pay more attention to exercise, increase resistance, stay up less at night, and eat less junk food.
