Trichomoniasis has two transmission routes: sexual contact and indirect exposure. For instance, if a public bath seat, swimming pool chair, or toilet seat is contaminated with secretions from an infected individual, subsequent users who sit directly on these surfaces may become infected.
Therefore, it is advisable to avoid using public toilet seats whenever possible. If unavoidable, take thorough hygiene precautions. When traveling, carry disposable toilet seat covers. Refrain from soaking in hotel bathtubs indiscriminately, as trichomonads exhibit strong environmental resilience and thrive at bath temperatures around 40°C (104°F). Furthermore, strictly avoid swimming in poorly disinfected pools.
Furthermore, virtually no bacteria can be transmitted through direct skin contact with toilet seats. In public restrooms, your primary concern should be bacteria spread via the fecal-oral route—not skin infections. Fecal-oral transmission refers to bacteria and viruses in excrement that contaminate the environment and enter the body through the mouth.
② Cross-infection
Sexual activity can easily lead to cross-infection. If you have trichomoniasis, ensure your partner receives concurrent treatment. Otherwise, he may remain a carrier and reinfect you. Men often show no symptoms when infected, making it easy to overlook. However, once transmitted to you, it can cause numerous uncomfortable symptoms.
