I was wondering if and how long trichomonas can lie dormant in a man or woman. My partner cheated on me many years ago, but swears that he hasn't done it since then. I need to know asap. Thank you.

See doctor. You have a question as to cheating from your partner and the risks of sexually transmitted diseases. Se your doctor with your partner. There are deep trust issues at stake and the concern for std's. Trichomonas is not a virus. There are new vaccines for prevention of the std which causes a form of cervical cancer. Explore your concerns with your partner and your physician.
