Trichomoniasis in Teens

Trichomoniasis is a common sexually transmitted infection (STI). It’s also known as trich. It can cause vaginal redness and swelling (inflammation) in teen girls. In teen boys it can cause painful urination. Some experts say that millions of people in the U.S. have trich. But only about 30 out of 100 of them have any symptoms. Without treatment, the infection can linger for years.

This STI is not a life-threatening illness. It is often easy to cure. But it's important to get it treated right away. That’s because trich can make it easier for a teen girl or a woman to get HIV during sex. In pregnant women, the infection is linked to preterm birth and babies that are smaller than normal.
