What is trichomoniasis?

Trichomoniasis is a sexually transmitted infection (STI) caused by a parasite belonging to the protozoan family, trichomonas vaginalis. It mainly affects young women, and can cause vaginitis in women and urethritis in men.

Trichomoniasis is the most common STI in the world.

Most often asymptomatic, especially in men, trichomoniasis can nevertheless be accompanied by symptoms, mainly urogenital, such as

  • Vaginal irritation or itching
  • Pain during urination or sexual intercourse

How is Trichomonas vaginalis infection transmitted?

Genital Trichomonas infections are almost always sexually transmitted. Women can be infected through sex with men or women. But men can only be infected through sex with women, not men.

Less frequently, transmission through damp towels, bath water or previously contaminated toilet seats is also possible. The parasite can live for up to 24 hours in outdoor environments if conditions are right.

What are the possible complications of Trichomoniasis?

The infection can cause pelvic inflammatory disease and, in pregnant women, premature labour and delivery.

In men, the only rare complications are epididymitis (inflammation of the duct connecting the testicle to the prostate) and prostatitis (inflammation of the prostate).

What is Trichomoniasis testing?

Trichomoniasis screening is done by vaginal and urethral smear in women by the gynaecologist and by a urine sample in men by the doctor or urologist. This can be done as early as the fifth day after infection.

If trichomoniasis is suspected, screening for other STIs, especially gonorrhoea and HIV, is recommended.

Trichomonas: treatment

Treatment is based on the oral administration of an antiparasitic antibiotic of the nitroimidazole family. Treatment may be given in a single dose or over several days depending on the symptoms.

All infected persons (patient and all known partners) should be treated and sexual intercourse should be avoided until treatment is completed and recovery is complete.

How can trichomonas vaginalis infection be prevented?

There is no vaccine to prevent Trichomonas vaginalis infection. To avoid trichomoniasis, a condom (internal or external) should be used during sexual intercourse.
