Can an STD cause bacterial vaginosis?
Trichomoniaisis can cause bacterial vaginosis, but most women with BV don't have an STD.
BV is not a STD. Having sex can cause BV because it may cause an increase in harmful bacteria in the vagina. Multiple sex partners increases the chances of getting BV. Bacterial vaginosis is not an STD. It's not clear. BV has been previously classified as an STD but the CDC seems to be reconsidering that position.
Bacterial vaginosis is not an inflammatory condition, and so it does not cause cervicitis. A women with only bacterial vaginosis does not present with redness, swelling or heat in the vagina, vulva, or cervix. Trichomonas, which is almost always accompanied by BV, may cause inflammation of the female genitalia (vulvitis, cervicitis, and/or vaginitis.)
Bacterial vaginosis can not cause HIV, contracting the virus is what gives people people a positive HIV status. However if you have bacterial vaginosis then you may be more likely to contract HIV if you are having unprotected sex because the normal protective barrier of the skin may be damage by the bacterial infection and therefore more permeable to the virus
