Trichomoniasis, sometimes referred to as "trich," is a common STD that affects 2 to 3 million Americans yearly. It is caused by a single-celled protozoan parasite called Trichomonas vaginalis. Trichomoniasis is primarily an infection of the urogenital tract; the urethra is the most common site of infection in man, and the vagina is the most common site of infection in women.
