Trichomoniasis

What is trichomonasis?

Trichomonasis vaginalis (also known as trich) is a parasite that can live in the vagina and urethra (opening on the penis). It can survive for a short period of time outside the body.

Trichomonasis is transmitted through unprotected vaginal and anal intercourse with an infected partner.

  • Fishy odour
  • Frothy yellowish vaginal discharge
  • Itching and redness of the vulva and/or vagina
  • Burning with urination
  • Slight discharge from the penis and discomfort while urinating

Trichomonasis is diagnosed by a health care provider based on symptoms;  swabs are taken from the vagina or penis to confirm.

  • Trichomonasis can be treated and cured with oral antibiotics.
  • It is important not to have sexual contact during treatment and for seven days after treatment.
  • Make sure that your partner(s) is treated before resuming any sexual activity.
  • You can be re-infected after treatment.
  • When testing for trichomonasis, other sexually transmitted infections (STIs) must be considered, and additional testing for other STIs should be done.

Remember:

Any infection in the genital areas may increase the risk of becoming infected with HIV. Practicing safer sex, by using latex or polyurethane condoms and/or oral dams for oral, anal or vaginal sex can reduce the risk of sexually transmitted and blood borne infections (STBBIs).
