Transmission of BV: Excellent question -- without a clear answer. BV acts like an STD (more common in people with STDs or at risk) but treating male sex partners doesn't prevent recurrence. However, condoms may help prevent new episodes. BV is definitely transmitted sexually in lesbians who share vaginal fluids via fingers, sex toys, etc. It definitely is not contagious by nonsexual contact, e.g. shared bathroom.

To clarify "acts like an STD": That's true only in some aspects, such as being more frequent in people with STDs or at risk. However, most cases of BV occur without apparent STD risk, i.e. in monogamous persons and sometimes in women not recently sexually active at all. Medical science simply has not yet been able to figure out why the bacterial overgrowth happens.
