Trichomoniasis (trich) is an infectious disease caused by the parasite Trichomonas vaginalis.[2] About 70% of affected people do not have symptoms when infected.[2] When symptoms occur, they typically begin 5 to 28 days after exposure.[1] Symptoms can include itching in the genital area, a bad smelling thin vaginal discharge, burning with urination, and pain with sex.[1][2] Having trichomoniasis increases the risk of getting HIV/AIDS.[1] It may also cause complications during pregnancy.[1]
Trichomoniasis is a sexually transmitted infection (STI) most often spread by vaginal, oral, or anal sex.[1] It can also spread through genital touching (manual sex).[1] People who are infected may spread the disease even when symptoms are not present.[2] Diagnosis is by finding the parasite in the vaginal fluid using a microscope, culturing the vaginal fluid or urine, or testing for the parasite's DNA.[1] If present, other STIs should be tested for.[1]
Methods of prevention include not having sex, using condoms, not douching, and being tested for STIs before having sex with a new partner.[1] Although not caused by a bacterium, trichomoniasis can be cured with certain antibiotics (metronidazole, tinidazole, secnidazole).[1] Sexual partners should also be treated.[1] About 20% of people get infected again within three months of treatment.[2]
There were about 122 million new cases of trichomoniasis in 2015.[3] In the United States, about 2 million women are affected.[1] It occurs more often in women than men.[1] Trichomonas vaginalis was first identified in 1836 by Alfred Donné.[4] It was first recognized as causing this disease in 1916.[5]
