Trichomoniasis (Trich) is one of the most common sexually transmitted infections. This infection is caused by a one-celled parasite named Trichomonas Vaginalis. It is capable of affecting anyone that is sexually active, though it affects women more than men and older women more often than younger women. 

For women the most commonly infected part of the body is the lower genital tract (vulva, vagina, cervix or urethra), while for men is usually the urethra.

Trichomoniasis does not usually produce visible symptoms or problems in roughly 70% of cases, but those affected may notice itching or irritation in affected area(s), discomfort during urination, or discharge from either the vagina or penis. If left untreated, the infection can last for months or years and it can raise the chances of receiving or spreading other STDs.
