What symptom would be a major indicator of Trichomoniasis?

The major indicator of Trichomoniasis is the presence of a foul-smelling discharge. This sexually transmitted infection is caused by the protozoan parasite Trichomonas vaginalis and is characterized by a distinct symptom profile, one of the hallmark signs being abnormal vaginal discharge. In women, this discharge often appears yellow-green and has a strong, foul odor. While itching or irritation in the genital area can also occur, it is the foul-smelling discharge that is most notably associated with Trichomoniasis and serves as a key diagnostic feature. Recognizing this symptom can aid healthcare providers in directing appropriate treatment and care for those affected by this infection.
