N: 1. 1950, from trichomonas, genus of a family of flagellate parasite (from tricho-, latinized form of Greek trikho-, combined form of thrix (genitive trikhos) “hair” + –monas).
2. Trichomonas: A single-celled protozoan parasite best known in medicine because one species causes vaginitis (vaginal inflammation). Infection with trichomonas (trichomoniasis) is the most common curable sexually transmitted disease (STD) in young sexually active women) in young sexually active women. The species of trichomonas responsible for STD is Trichomonas vaginalis. The vagina is the most common site of infection in women, and the urethra (urine canal) is the most common site of infection in men. The parasite is sexually transmitted through penis-to-vagina intercourse or vulva-to-vulva (the genital area outside the vagina) contact with an infected partner. Women can acquire the disease from infected men or women, but men usually contract it only from infected women.
3. Trichomonas is usually passed from one person to another during sex. The infection can be spread through unprotected vaginal sex and possibly through sharing sex toys if you don’t wash them or cover them with a new condom each time they are used. We don’t know if the infection can be spread between women by rubbing vulvas (female genitals) together or by transferring discharge from one vagina to another on the fingers. It is possible for a pregnant woman to pass the infection to her baby at birth. You cannot catch trichomonas from oral or anal sex, or from kissing, hugging, sharing cups, plates or cutlery, toilet seats or towels.
