Trichomonas vaginalis

Trichomoniasis is a sexually transmitted infection (STI) caused by a tiny parasite called Trichomonas vaginalis (TV).
Symptoms of trichomoniasis
Symptoms of trichomoniasis usually develop within a month of infection, although up to half of all infected men and women have no symptoms.
Diagnosing trichomoniasis
Trichomoniasis can sometimes be difficult to diagnose because symptoms are similar to those of other sexually transmitted infections (STIs).
Treating trichomoniasis
Trichomoniasis is unlikely to go away without treatment. The infection may cure itself in rare cases, but you risk passing the infection on to someone else if you are not treated.
Preventing trichomoniasis
If you have had trichomoniasis and it has been treated, you will not be immune to the infection and you can get it again.
