Sexually transmitted infections (STIs) are more common than many people think and understanding them is key to staying safe. In this edition of our STI spotlight series, we’re taking a closer look at Trichomoniasis – a lesser-known but important infection to be aware of.

What is Trichomoniasis?

Trichomoniasis, often called trich, is an STI caused by the parasite Trichomonas vaginalis. It affects both men and women, primarily targeting the genital and urinary tracts. While anyone can contract trichomoniasis, it is diagnosed more frequently in women. Left untreated, it can increase the risk of acquiring other STIs, including HIV, making early detection and treatment essential.

Symptoms of Trichomoniasis

One of the tricky aspects of trichomoniasis is that around 70% of people with the infection experience no symptoms. This means it can be unknowingly passed between partners. When symptoms do appear, they can vary by person and gender:

• For women: Symptoms may include frothy, yellow-green vaginal discharge with an unpleasant smell, genital irritation, discomfort during sex or urination, and, in rare cases, lower abdominal pain.
• For men: Symptoms tend to be milder but may include irritation inside the penis, mild discharge, or a slight burning sensation after urination or ejaculation.

How is Trichomoniasis Diagnosed?

Since many people don’t experience symptoms, testing is the only way to confirm a trichomoniasis infection. A healthcare provider may recommend:

• A physical examination to check for signs of infection.
• Lab tests, such as a vaginal fluid sample for women or a urine sample/swab from the penis for men, to detect the presence of T. vaginalis.

If you suspect you might have trichomoniasis, Suffolk Sexual Health Service offers confidential and free STI testing. You can also order a home testing kit through our online portal for added convenience here.

Treatment and Prevention

The good news is that trichomoniasis is completely curable with a prescribed course of antibiotics. To stop reinfection, it’s important for all sexual partners to receive treatment at the same time. During treatment, it’s recommended to avoid sexual contact until both partners have completed their medication and any symptoms have cleared.

Preventing trichomoniasis follows the same principles as preventing other STIs:

• Use condoms consistently and correctly when having sex with new or multiple partners. Get the eC-Card app to order free condoms.
• Get regular STI check-ups, especially if you have new partners.
• Encourage open conversations about sexual health with your partner(s).
