Bacterial vaginosis (BV) is not considered a sexually transmitted infection (STI), and it is not directly contagious from person to person. However, sexual activity, especially unprotected sex, can increase the risk of developing BV. This is because certain sexual practices, such as having multiple sexual partners and douching, can disrupt the balance of bacteria in the vagina, which can lead to the development of BV.
It is also important to note that having BV can increase the risk of acquiring STIs, including HIV, and can also increase the risk of complications during pregnancy. If you have BV, it is important to practice safe sex and to use condoms to reduce the risk of transmitting or acquiring STIs. If you are experiencing symptoms of BV, such as unusual discharge, abnormal vaginal odor, or itching, it is important to see a healthcare provider for proper diagnosis and treatment.
