Vaginal discharge is a common symptom of genital infection in women. I
dentifying its source can be challenging, because a large number of pa
thogens cause vaginal and cervical infection, and several infections m
ay coexist. Patient history and physical examination findings may sugg
est a diagnosis. Useful tests for etiologic diagnosis include pH analy
sis of vaginal fluid, the ''whiff'' test, wet mount examination, cultu
re, and Gram's stain, Once the source of infection has been identified
, the patient can be treated, usually with oral antibiotics, oral anti
fungals, or topical vaginal preparations
