Trichomoniasis, also known as trich (say "trick"), is an infection caused by a parasite. The infection spreads through sexual contact.

Women are more likely to have symptoms than men. The infection can cause a discharge from the vagina that smells bad.

The infection is treated with antibiotics. If you are infected, it's important for your sex partner to take medicine too.
