What is it?

Trichomoniasis is a common sexually transmitted infection that affects both men and women. It is caused by the parasite Trichomonas Vaginalis.


Trichomoniasis is spread through sexual contact, specifically penile-vaginal sex or vulva-to-vulva contact. Women can contract the disease from infected partners of either sex, whereas men can only contract it from infected women. Using latex condoms during every sexual encounter as well as limiting the number of sexual partners can help prevent the spread of Trichomoniasis. These practices will also reduce the likelihood of acquiring other sexually transmitted infections.


Men very rarely experience any symptoms. Mild burning during urination or slight discharge may be experienced, but these cases are rare.

Women can also be asymptomatic, but are more likely to have symptoms than men. Symptoms can include a frothy yellow-green vaginal discharge with a strong odor, and discomfort during intercourse or urination. Some women experience itching and irritation of the genitals, with lower abdominal pain being a very rare symptom.


If you think you may have Trichomoniasis, or any other sexually transmitted infection, call Student Health at (215) 662-2853 for an immediate appointment. Trichomoniasis is fully curable with antibiotics. Sexual activity should be stopped during treatment, and all partners should be treated to prevent reinfection.

Even if the symptoms go away, medical treatment should be sought as the parasite can still be passed on to others. In addition, the full round of prescribed medicine should be taken. Trichomoniasis infection increases an individual’s vulnerability to more serious STDs, such as HIV.
