What Is Trichomoniasis and How Do You Get It?

Trichomoniasis (TRIK-uh-muh-NEYE-uh-suhss) is a sexually transmitted infection (STI) caused by a parasite. It is sometimes called "trich." Trichomoniasis is the most common curable STI found in young, sexually active women.

The parasite is spread through sexual contact. Women can get it by having penis-to-vagina intercourse with an infected man or vulva-to-vulva contact with an infected woman. Men usually get it only from infected women.
