Need to know more about trichomoniasis? We’ve got you covered.

Trichomoniasis is a common and treatable sexually transmitted infection (STI) caused by a parasite. Most people don’t have any symptoms, so they may not know they have it. 

Looking for information about trichomoniasis? We have you covered.

Trichomoniasis (usually called “trich”) is one of the most common sexually transmitted infections (STIs). It’s caused by the parasite trichomonas vaginalis.

Approximately 70% of people* infected with trichomoniasis do not experience symptoms, with most of those being people assigned male at birth (AMAB).

Common symptoms of trich* include the following:

  • Genital burning, itching, redness or soreness
  • Pain during urination
  • Pain during sex
  • Discharge from the penis or vagina

Pregnant people with trichomoniasis have a higher risk of giving birth prematurely and having a baby with a low birth weight.

People assigned female at birth (AFAB) may also experience the following symptoms:

  • Pelvic pain
  • Vaginal discharge with a foul smell that is thin or frothy

AMAB people may experience the following symptoms:

  • Burning during urination or after ejaculation
  • Pain or irritation from inside the penis
  • Thin, white discharge from the penis

Getting help

A MinuteClinic provider can review medical history and symptoms. They can perform a physical exam and order tests that use urine or vaginal fluid to check for trichomoniasis. They can prescribe medication and develop a treatment plan. They can also discuss safe sex practices to help prevent future infections.

Frequently asked questions

Trich can spread from person to person during sex without a condom. The parasite spreads from penis to vagina, from vagina to penis, or from vagina to vagina. It’s not common for it to spread to other parts of the body.

A health care provider may prescribe medication, if necessary. They may ask someone to abstain from sexual intercourse until the infection is fully cleared.

The only way to fully prevent infection is to avoid sexual activity.* However, there are steps people can take* to help prevent and reduce the risk of infection:

  • Use a barrier prevention method like condoms during vaginal sex
  • Get annual screenings for STIs
  • Have a partner tested before any sexual activity
  • Be in a mutually monogamous relationship where both partners have been tested
  • Avoid sex with people who show symptoms

A MinuteClinic provider can review medical history and symptoms. They can perform a physical exam and order tests that use urine or vaginal fluid to test for trichomoniasis.
