The WSLH Communicable Disease Division has added a Trichomonas vaginalis NAAT test.
Vaginal infections caused by Trichomonas vaginalis are among the most common conditions transmitted sexually.1 It is estimated that in the United States 7.4 million new cases of trichomoniasis occur annually compared with 3 million cases of chlamydia and 718,000 cases of gonorrhea.2 Trichomoniasis is not a nationally reportable infection.3
Trichomoniasis is caused by the parasitic protozoan Trichomonas vaginalis. About 70% of women and men do not have symptoms when infected. When symptoms do occur they typically begin 5 to 28 days after exposure. Symptoms can include itching in the genital area, a bad smelling thin vaginal discharge, burning with urination, and pain with sex.2 Having trichomoniasis increases the risk of getting HIV/AIDS. It may also cause complications during pregnancy.
