Trichonomics: 9 Facts on Trichomoniasis

Out of the common sexually transmitted infections (STIs), trichomoniasis is a condition less familiar to many. Unlike prevalent bacterial infections such as chlamydia and gonorrhea,  trichomoniasis is a parasitic infection. Despite its unfamiliarity, nearly 2 million people in the United States were diagnosed with this condition in 2018.¹ Keep reading to learn the facts about this STI.

The Facts

Obesity is linked to several chronic diseases including the following:

1. This STI is caused by the parasite Trichomonas vaginalis.
2. Some individuals have a higher likelihood of trichomoniasis infection. Women tend to have a higher prevalence than men. Also, studies have found that older women, and women of African American women tend to have a higher prevalence compared to other ethnic groups.^ibid
3. This STI is passed through unprotected sexual contact with a person with the parasitic infection. 
4. In many cases, individuals with the infection are asymptomatic. Only 30% of individuals with this infection have symptoms which may include discomfort during urination and sex, abnormal vaginal discharge, and itching or burning in the vaginal region.²
5. A person that is asymptomatic with trichomoniasis can still spread the infection to others.
6. Like many other STIs, this condition is diagnosed by getting a swab of the vaginal region and sending it to a lab for confirmation of the presence of the parasite.
7. Trichomoniasis is a curable condition. Providers can prescribe medications to eliminate the parasite. However, in the meantime sexual activity should be paused until the completion of medication. 
8. Complications may arise from this infection if left untreated. For example, there is an increased likelihood of contracting HIV. Furthermore, pregnant women with trichomoniasis are at risk of having a preterm delivery.^.1
9. Abstinence from sexual activity is the best way to prevent contracting trichomoniasis. However, wearing condoms and getting STI screenings with your partner prior to engaging in sexual behaviors can minimize your risk.
