Which of the following is a common symptom of Trichomonas vaginalis infection?

A common symptom of a Trichomonas vaginalis infection is foul-smelling discharge. This parasitic infection is one of the most prevalent sexually transmitted infections and often affects the genital and urinary tracts. In females, the infection can lead to symptoms like vaginal discharge that may be characterized as frothy and have a strong, unpleasant odor. This discharge results from the irritation and inflammation caused by the presence of the protozoan parasite.

Foul-smelling discharge serves as a key diagnostic feature of the infection, helping healthcare providers distinguish it from other types of vaginitis or sexually transmitted infections. Identifying this symptom is critical in guiding effective treatment and management of the infection. In contrast, symptoms such as weight loss, fever, or abdominal pain are generally not indicative of a Trichomonas vaginalis infection and may suggest other medical conditions.
