Frothy, greenish-yellow vaginal discharge is a classic symptom of Trichomoniasis, particularly in women. This distinctive discharge is a result of the infection caused by the parasitic protozoan Trichomonas vaginalis. The discharge may be accompanied by a strong odor and is often associated with inflammation of the vaginal and cervical tissues, which can lead to additional symptoms like itching and irritation.

While other symptoms, such as genital itching and painful urination, can occur with Trichomoniasis, they are not as definitive or characteristic as the frothy discharge. Abdominal pain can also be present, but it is more ambiguous and not a primary indicator of this specific infection. The unique nature of the discharge is critical in identifying Trichomoniasis and is a key differentiator from other sexually transmitted infections.
