[1] Symptoms can include itching in the genital area, a bad smelling thin vaginal discharge, burning with urination, and pain with sex.

[1] Trichomoniasis is a sexually transmitted infection (STI) most often spread by vaginal, oral, or anal sex.

[6] Symptoms include pain, burning or itching in the penis, urethra (urethritis), or vagina (vaginitis).

For women, there may also be a yellow-green, itchy, frothy, foul-smelling ("fishy" smell) vaginal discharge.

[23] There are no routine standard screening requirements for the general U.S. population receiving family planning or STI testing.

[24] The advent of new, highly specific, and sensitive trichomoniasis tests presents opportunities for new screening protocols for both men and women.

[24][27] Careful planning, discussion, and research are required to determine the cost-efficiency and most beneficial use of these new tests for the diagnosis and treatment of trichomoniasis, which can lead to better prevention efforts.

[24][27] Several strategies have been found to improve follow-up for STI testing, including email and text messaging as reminders of appointments.

[28] Evidence from randomized controlled trials for screening pregnant women who have no symptoms of infection with trichomoniasis and treating women who test positive for the infection have not consistently shown a reduced risk of preterm birth.

[9] Women living with HIV infection have better cure rates if treated for seven days rather than with one dose.

[31][36] Topical treatments are less effective than oral antibiotics due to Skene's gland and other genitourinary structures acting as reservoirs.
