HOME CARE ADVICE FOR TRICHOMONAS

  1. How is trichomonas transmitted?
    • Trichomonas is spread by sexual intercourse (vaginal).
    • Some women and many men do not have symptoms when they are infected. As a result, trichomonas can be passed along with neither sexual partners knowing that it is occurring.
  2. How long does it usually take for symptoms to appear once one is exposed?
    • The incubation period is 4 days to 4 weeks.
  3. How can I get tested for trichomonas?
    • Inspection of a sample of the vaginal discharge under the microscope.
    • May also be found on a Pap smear.
  4. Is there treatment for trichomonas?
    • Antibiotic therapy is needed. A person with trichomonas is contagious until he or she has been treated.
    • Sexual partners should also be evaluated and treated.
  5. STD National Hotline
    • The CDC National STD Hotline provides information on sexually transmitted diseases (STDs), such as chlamydia, gonorrhea, HPV/genital warts, herpes, and HIV/AIDS. Specialists can provide general information, referrals to local clinics, and written materials about STDs and disease prevention.
