STD Information: Trichomoniasis
"Trich", a tiny protozoa, can present like BV, but unlike BV, "trich" is definitely an STD. It lives in the moist areas of the genitals of infected people (e.g. vaginal fluid, genital glands).
- Symptoms: Often causes foamy discharge with foul odor, but symptoms may be absent. Painful urination, itching or irritation are sometimes present. If symptoms occur, they usually occur 4-20 days after infection but can begin much later.
- Transmission WTW: clearly documented, and probably underestimated. Partners should absolutely be evaluated and treated. Both partners should abstain from sexual activity until treated.
- Treatment: metronidazole (an antibiotic) in a single dose. Partners should be treated.
Please note that for the purpose of our web site we are focusing primarily on woman to woman transmission (WTW) and only providing a general overview of the infections themselves.
