Vaginitis is an inflammation or infection of the vagina that can cause itching, burning, pain, discharge, and bad odor. Vaginal symptoms are a common reason women seek medical care. There are many types of vaginitis, each with its own cause, symptoms, and treatment. Pregnant women with some types of vaginitis may be at higher risk of preterm birth.

NICHD scientists are seeking to understand better the types of vaginitis, the link between vaginal infections and pregnancy complications, and ways to promote vaginal health.
