What is Trichomonlasis?

Trichomoniasis, “trich” for short, is caused by a parasitic flagellated protozoan called trichomonas vaginalis, which thrives in the alimentary and genitourinary tracts of humans and other hosts.

Usually acquired by sex without a condom, or occasionally from wet towels, underwear, or sex toys, trichomoniasis can easily invade the urinary tract and cause infection. Carriers can be infected for three to 28 days before symptoms arise.

Men with trichomoniasis rarely show signs. Women may see a watery, yellowish or greenish, bubbly discharge; smell an unpleasant odor; and feel pain and itching during urination; especially after their periods.

Trich can be treated with antibiotics, including metronidazole, taken orally. Both patient and sex partners should be tested and treated.
