How is trichomoniasis transmitted?

Trichomoniasis is transmitted through sexual intercourse. It is most common in people who are at their peak of sexual activity (teens and 20s), but it is found in higher rates among older women than other sexually transmitted diseases (STDs). Having multiple sex partners and infection with other STDs are primary factors that increase a woman's risk for infection.

In very rare cases, trichomoniasis may be transmitted by a pregnant woman to her baby during childbirth. Pregnant women with trichomoniasis are more likely to deliver early and to give birth to a low-birth-weight baby (less than 5.5 pounds). Their babies are also more likely to have conjunctivitis.

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.
