Trichomoniasis, or trich (pronounced ‘trick’), is a common STI. It is caused by a tiny parasite called trichomonas vaginalis.
In women, trichomoniasis can cause a foul-smelling vaginal discharge. It can also lead to genital itching and painful urination. Most men who have trichomoniasis have no symptoms.
It is easy to treat but most people don’t have any symptoms. If you’ve had unprotected sex and are worried about trichomoniasis or other STI's it’s important to get tested as soon as possible.
