Public Health Fact Sheet
What is Trichomoniasis?
Trichomoniasis is a very common and persistent sexually transmitted disease caused by protozoan parasite called Trichomonas vaginalis.
How is Trichomoniasis spread?
Trichomoniasis is spread when the parasite is passed from one person to another during oral, anal, or vaginal sex with someone who is infected.
How is Trichomoniasis treated?
Trichomoniasis can be treated with prescription medication. It is safe for pregnant women to take this medication. People who have been treated for Trichomoniasis can get it again. About 1 in 5 people get infected again within three months after receiving treatment. To avoid getting re-infected, make sure that all of your sex partners get treated. Also, wait 7-10 days after you and your partner have been treated to have sex again. Get checked again if your symptoms come back.
How can Trichomoniasis be prevented?
Abstinence from sexual activity is the best form of prevention. If you choose to have sex, limit your partners. The more people you have sex with, the greater the chance of getting exposed to an STD. Use a new condom every time you have sex. Have regular exams and have STD testing done at least yearly if you are sexually active.
