What is Trichomoniasis

  • Caused by a single-celled protozoan parasite called Trichominas vaginalis
  • A common and curable sexually transmitted disease


  • Transmitted through contact with fluids from the penis or vagina from an infected partner
  • Women can acquire the disease from infected men or women

Pregnancy Complications

  • Pregnant women with trichominiasis may have babies who are born early or with low birth weight


  • Made by lab tests and physical exam
  • The parasite is harder to detect in men than in women


  • Treated with antibiotics
  • All sex partners should be notified, evaluated, tested, and treated
  • Persons with Trichomoniasis should abstain from sexual contact until they and their sex partners have completed their treatment


  • Most men do not have symptoms
  • Some men may have an irritation on the inside of the penis, mild discharge, or slight burning after urination or ejaculation
  • Some women have a discharge that is frothy, yellow-green that has an odor
  • Infection may cause discomfort during sex and urination, itching or irritation of the genital area
  • Symptoms usually appear between 5-28 days after exposure


  • The genital inflammation caused the trichomoniasis can increase a woman’s chances of acquiring HIV infection


  • Prevention is best achieved by abstinence from sexual contact, or to be in a long-term mutually monogamous relationship
  • The use of latex male condoms consistently and correctly can reduce the risk of transmission
  • Women and men with new partners should be tested for all sexually transmitted diseases
  • Transmission of an STD cannot be prevented by washing the genitals, urinating, and/or douching after sex
  • Cannot be spread through contact with toilet seats, doorknobs, swimming pools, hot tubs, bathtubs, shared clothing, eating utensils
