Research has shown T vaginalis infection increases the risk of HIV transmission in both men and women. [3, 1] It is estimated that, in women alone, 747 new HIV cases per year result from the facilitative effects of T vaginalis on the transmission of HIV. [66] Overall, persons with trichomoniasis are twice as likely to develop HIV infection as the general population. [35] Symptomatic men with comorbid T vaginalis and HIV infections have been found to have significantly higher numbers of HIV RNA particles in their seminal fluid. [3] Treatment of trichomoniasis has been shown to decrease the rate of viral shedding in patients with HIV infection. [3, 67]
