What is Trichomoniasis?
Trichomoniasis, or "trich," is a common, treatable sexually transmitted disease (STD) caused by Trichomonas vaginalis, a protozoan parasite.
How do you get Trich?
Sexually active people can get trich by having sex without a condom with a partner who has trich. It is most found in the female lower genital tract (vulva, vagina, cervix, urethra) or inside the penis (urethra). Trich can increase the risk of getting or spreading other STDs.
What are the symptoms of Trich?
About 70% of people with the infection do not have any signs or symptoms. When trich does cause symptoms, they can be mild or severe. Some people get symptoms within 5-28 days after getting the infection. Others do not develop symptoms until much later. Symptoms can come and go.
A person may notice itching, burning, redness, or soreness of the genitals, vagina, or both; discomfort when urinating; a clear, white, yellowish, or greenish vaginal discharge with a fishy smell.
A person may notice itching or irritation inside the penis, burning after urinating or ejaculating, and discharge from the penis.
How do you test for Trich?
Your health care provider will examine you and test a small amount of urine or discharge from the vagina or penis for trich.
What is the treatment for Trich?
Your health care provider will treat you with medicine (pills) taken by mouth. Treatment of all sex partners is important to prevent the spread of infection and avoid reinfection.
What about pregnancy?
Pregnant women with trich are more likely to have their babies early. Also, their babies are more likely to have a low birth weight.
