INFECTION & TRANSMISSION OF TRICHOMONIASIS
The human genital tract is the only reservoir for this species. Trichomonas is transmitted through sexual or genital contact. Although internet searches may yield common theories of transmission from objects (e.g. toilet seats, towels), they have not been reliably established.
Trichomoniasis is associated with increased risk of transmission of HIV and it may cause a woman to deliver a low-birth-weight or premature infant.
Trichomoniasis is also associated with increased chances of cervical cancer in females and higher risk of prostate cancer development in males.
