Vaginitis is an infection of the vagina. It is the most common vaginal condition presented. It is difficult to determine any one organism most responsible for vaginitis. This is because it varies due to age, sexual activity, and method of microbial identification. Vaginitis is not necessarily caused by a sexually transmitted infection. Vaginitis is diagnosed based on the presence of vaginal discharge, which can have a certain color, odor, or quality.
