Trichomoniasis (called trich for short) is a sexually transmitted disease (STD) that is caused by a parasitic protozoa organism called trichomoniasis vaginalis. This organism lives in the lining of the vaginal walls, vulva or urethra and produces an odorous, foamy and irritating discharge. Symptoms might also include pain during intercourse, pain during urination and itching. Most people do not show symptoms.
Trich can be passed between sexual partners. If one partner becomes infected with trich, their sexual partners should also be treated so the infection does not continue to be passed between them. Trich can be cured with antibiotics.
