Trichomoniasis (Trike-o-moan-eye-a-sis)

Trichomoniasis is an infection caused by a microscopic parasite in the vagina or urethra (tube you pee through). This is not usually a very common infection.

How is it passed on?

  • Unprotected vaginal sex
  • Shared sex toys that have been in contact with bodily fluids


Often no symptoms but may include:

  • frothy, yellow-green discharge (fluid) from the vagina
  • unpleasant vaginal odour (smell)
  • irritation – itching burning in the vagina
  • guys may have a burning pain when peeing

How is it tested?

  • Swab sample from the vagina or penis
  • Urine sample (pee in a cup)

How is it treated?

  • A single dose of antibiotic tablets.
  • Sexual partner/s will need to be treated at the same time.
  • Avoid having sex while you are taking the antibiotics and for seven days after you have both been treated to prevent passing the infection onto someone else or becoming infected again yourself.

How can I prevent getting it?

  • Use a condom during vaginal sex and when sharing sex toys.
