B. Clinical features. Trichomoniasis in women ranges from an asymptomatic state to a severe, acute, inflammatory disease. Signs and symptoms include a purulent, malodorous, thin discharge (70%) with associated burning, pruritus, dysuria, and dyspareunia. Physical examination reveals erythema of the vulva and vaginal mucosa; the classic green-yellow frothy discharge is observed in 10-30%. Punctate hemorrhages may be visible on the vagina and cervix in 2%.
C. Complications. Infection is associated with premature rupture of the membranes and prematurity; however, treatment of asymptomatic infection has not been shown to reduce these complications. Trichomoniasis is a risk factor for development of post-hysterectomy cellulitis. The infection facilitates transmission of the human immunodeficiency virus.
