Trichomoniasis: Symptoms, Diagnosis, Treatment & Complications

What is Trichomoniasis?

Trichomoniasis, commonly called “trich”, is recognised as being one of the most common forms of sexually transmitted infections (STIs), which is actually able to lie dormant for a number of years and does not always result in any symptoms, unfortunately making it easily spreadable. This parasitic infection is identified as being caused by the trichomonas vaginalis parasite, invading the vagina (women) or urethra (men).


Trichomoniasis is normally transmitted sexually through contact between the penis and vagina or between two women through vulva on vulva contact. Unlike many STI's, trichomoniasis can also be transmitted through contact with damp items such as towels.
