Trichomoniasis is a sexually transmissible infection (STI). It is caused by the organism Trichomonas vaginalis (a protozoan parasite).

How did I get infected with trichomoniasis?

Trichomoniasis is passed on by having vaginal or anal sex without a condom with someone who has the infection.

What are the symptoms of trichomoniasis?

  • An increase in the amount or change in the colour of vaginal discharge
  • Vaginal itching and burning
  • Stinging or burning when passing urine
  • Discharge from your penis, but often there may be no symptoms

How is trichomoniasis diagnosed?

Testing is done from a urine sample or swab from the vagina or anus, which is sent to the laboratory for testing.

What is the treatment for trichomoniasis?

Trichomoniasis is treated with oral antibiotics.

What can happen if trichomoniasis is not treated?

Trichomoniasis can make having sex uncomfortable. If you have trichomoniasis while you are pregnant, your baby may be born early and/or weigh less than expected.

What should I tell my partner(s)?

It is very important to tell your sex partner(s) that you have been diagnosed with trichomoniasis. They can be tested and treated if needed. Your health care provider can help you work out who you need to tell and how to tell them.

How do I avoid getting infected again?

  • Make sure that your current sexual partner(s) are tested and treated
  • Use a condom with sexual partners
  • Have regular STI check-ups.
