The most common vaginal infections are:

  • Bacterial vaginosis
  • Trichomoniasis
  • Vaginal yeast infection

Some vaginal infections are transmitted through sexual contact, but others,
such as yeast infections, probably are not.


Bacterial vaginosis (BV) is the most common cause of vaginitis symptoms among
women of childbearing age. It previously was called nonspecific vaginitis or
Gardnerella-associated vaginitis. Health experts are not sure what role
sexual activity plays in BV.
