Trichomoniasis
What Is Trichomoniasis?
Trichomoniasis (or "trich") is a very common sexually transmitted disease (STD) caused by infection with the protozoan parasite Trichomonas vaginalis. Although symptoms can vary, most people who have trichomoniasis do not have any noticeable signs or symptoms.

Symptoms
About 70% of people with trichomoniasis do not experience any signs or symptoms. When symptoms do occur, they can range from mild irritation to severe inflammation.
Men with trichomoniasis may notice:
- Itching or irritation inside the penis
- Burning after urination or ejaculation
- Discharge from the penis
Women with trichomoniasis may notice:
- Itching, burning, redness, or soreness of the genitals
- Discomfort when urinating
- A clear, white, yellowish, or greenish vaginal discharge with a fishy odor
How is Trichomoniasis Spread?
Sexually active individuals can contract trichomoniasis by having unprotected sex (without a condom) with a partner who has the infection. The parasite is typically spread through penis-to-vagina, vagina-to-penis, or vagina-to-vagina contact during sexual activity.
Risks and Complications
Trichomoniasis can increase the risk of acquiring or transmitting other sexually transmitted infections, such as HIV. It can also cause genital inflammation, making it easier to contract or pass on HIV to a sexual partner.
In pregnant individuals, trichomoniasis increases the likelihood of preterm delivery and low birth weight in the baby.
Testing and Treatment
Trichomoniasis cannot be diagnosed based on symptoms alone. Healthcare providers can perform a physical examination and order laboratory tests to confirm the diagnosis.
Trichomoniasis is treated with oral antibiotic medications, such as metronidazole, tinidazole, or secnidazole. It is crucial that all sexual partners receive treatment simultaneously to prevent reinfection.
To prevent reinfection, individuals should abstain from sexual activity until they and their partner(s) have completed treatment.
