    Abstract:
    Trichomonas vaginalis (TV) can be infected with double-stranded RNA (dsRNA) viruses that may have important implications for trichomonal virulence and disease pathogenesis. A cross-sectional study was conducted in a sexually transmitted diseases clinic to determine the prevalence and clinical significance of dsRNA viral infection of TV infecting men and women. Overall, dsRNA virus was present in 21 (75%) of 28 TV isolates (95% confidence interval [CI], 55%-89%). dsRNA viral infection of TV was not associated with the presence of discharge, dysuria, genital pruritus, or genital irritation or odor. However, patients with virus-positive isolates were significantly older than patients with virus-negative isolates (median age, 38 vs. 23 years; P=.003), and virus-positive isolates were more prevalent among women (19 [86%] of 22 isolates; 95% CI, 65%-97%) than among men (2 [33%] of 6 isolates; P=.02). The age and sex specificity of virus-positive isolates may aid in understanding the differences in chronicity and clinical presentation of TV in men and women.
