What is trichomoniasis


Pathogen and transmission

Trichomonads are parasites that are often transmitted through sexual contact. Other ways of infection are rare, e. B. The parasites from the bladder or rectum can get into the vagina or be passed on indirectly, favored by a moist and alkaline environment. This can very rarely happen, for example, by sharing damp textiles / objects (towels) or by using non-chlorinated bath water. Transmission from the mother to the newborn is also possible.

Clinical picture

The infection is often asymptomatic. In half of the women there are no symptoms, in men the course without symptoms is the rule. If there are symptoms, these are expressed as itching, with a burning sensation when dissolving water and a sweet, foul-smelling discharge. If left untreated, infection can lead to sterility in both women and men.

Distribution and frequency

Trichomoniasis is the most common STI worldwide, with 5 million new cases per year worldwide. Young people are particularly affected, both men and women. Trichomoniasis can be treated with anti-parasitic drugs.


Condoms reduce the risk of contracting trichomonads. Infection can occur despite a condom. It is important to recognize an infection early and treat it.
