Transmission, symptoms and screening for trichomoniasis

How is trichomoniasis transmitted?

Trichomoniasis is an infection of the genitourinary system in men and women, caused by the parasite trichomonas vaginalis. It spreads through sexual contact with vaginal or urethral secretions of infected individuals. Much less frequently, it can also be transmitted via contaminated vaginal douche tips, speculums and toilet seats, as the parasite can survive up to 24 hours outside the body. Transmission from an infected mother to a newborn baby is also possible.

What are the symptoms of trichomoniasis?

In men, the infection is asymptomatic in 90% of cases. Although generally benign, complications can sometimes occur and lead to infertility.

In women, symptoms appear in about 50% of cases, and the infection can cause infertility or premature birth in pregnant women.

Main symptoms in women:

  • Yellowish or greenish vaginal discharge
  • Itching and redness of the vulva and vagina
  • Burning sensation when urinating
  • Fishy odour emanating from the vagina

How to get tested?

Screening for trichomonas vaginalis is based on a nucleic acid amplification test (NAAT) conducted on a vaginal or urine sample.
