Can trichomoniasis be transmitted?

The infection is caused by a parasite that can pass between sexual partners during genital contact. A person may carry it without discharge, itching, or discomfort, so feeling well does not rule it out. Trichomoniasis is not usually spread by toilet seats, swimming pools, or casual contact. A new diagnosis does not by itself show when the infection began or who transmitted it.

Testing is the way to clarify whether symptoms or a recent exposure are due to trichomoniasis. Other causes can produce similar vaginal changes, including [Vaginal Discharge](/symptoms/vaginal-discharge/) or [Vaginal Itching](/symptoms/vaginal-itching/).

Arrange a sexual-health assessment and follow the recommended test instructions. Until you and your partner or partners have completed treatment as advised, avoid sex or use the precautions your clinician recommends. Tell recent partners so they can seek assessment, even if they feel well. Take prescribed medicine exactly as directed and do not share it. Treatment is available through medical care, including [Antibiotic Treatment for Pelvic Infection](/treatments/medical-gynaecology/antibiotic-treatment-for-pelvic-infection/).

Seek prompt care for unusual discharge, genital itching, burning when urinating, pain during sex, or lower abdominal discomfort. Contact a clinician soon if you are pregnant, have had a partner diagnosed with trichomoniasis, or symptoms return after treatment. Severe pelvic pain, fever, vomiting, or feeling faint needs urgent assessment.

Ask which test is appropriate, whether partners need treatment, when sexual activity can safely resume, and whether you need testing for other sexually transmitted infections.
