Trichomoniasis is a sexually transmitted infection (STI).
A parasite passes between people during sex.
Your risk may be higher if you:
You may not always have symptoms. Symptoms appear in women more often than men. If you do have them:
Your doctor will ask about your symptoms, and sexual and health history. Your doctor will check the pelvic area for signs of infection.
A lab will check the samples for the parasite.
Antibiotics treat the infection. You should not have sex until you stop treatment and your symptoms are gone.
Part of care involves talking to your sexual partners. They may need healthcare even if they don’t have symptoms.
