What Is Trichomoniasis?
Trichomoniasis is a sexually transmitted infection (STI) caused by a microscopic parasite called Trichomonas vaginalis. It commonly affects the vagina in women and the urethra in men.
Many people have no symptoms, but untreated infection can increase the risk of other STIs and cause discomfort.
What Causes Trichomoniasis?
Trichomoniasis is spread through:
- Vaginal sex with an infected partner
- Sharing infected sexual devices
- Rarely, mother-to-baby transmission during childbirth
What Are the Common Symptoms of Trichomoniasis?
Symptoms may include:
- Vaginal discharge that is frothy, yellow-green, or unpleasant-smelling (women)
- Itching, redness, or irritation of the genitals
- Pain or burning during urination or sex
- Discomfort in the urethra (men, often mild or absent)
- Some people have no symptoms at all
How Is Trichomoniasis Diagnosed?
Diagnosis is usually through:
- Swab of the vagina, urethra, or urine test
- Laboratory testing to detect the parasite
Online GP consultations can advise on testing and provide guidance on sample collection. In-person testing may be needed for accurate results.
How Long Does Trichomoniasis Last?
- Untreated infection can persist for months or years
- Antibiotic treatment usually clears infection within a week
Is Trichomoniasis Contagious?
Yes. Trichomoniasis is transmitted through sexual contact. Condoms reduce the risk but do not completely eliminate it.
