T vaginalis infection is the most common nonviral STD in the world. Many patients (20-50%) are asymptomatic. If discharge is present, it is usually copious and frothy and can be white, gray, yellow, or green (the yellow and green colors are due to the presence of white blood cells [WBCs]). Local pain and irritation are common. Dysuria (20%), pruritus (25%), and postcoital bleeding due to cervicitis are other possible symptoms. Symptoms often peak just after menses.

Trichomoniasis is associated with risk factors for other STDs; accordingly, a history of multiple sexual partners should be elicited. Infection during pregnancy has been associated with preterm deliveries and low-birth-weight infants.

Trichomoniasis is rare in prepubertal children. Sexual abuse should be suspected if symptoms are present. Symptoms include a copious frothy discharge, local pain, irritation, and, occasionally, pruritus.
