Trichomoniasis: Trichomoniasis (or “trich”) is a common sexually transmitted disease cause by a parasite called Trichomonas vaginalis. Symptoms of the disease vary but most people with the parasite do not know they are infected. The parasite is passed from an infected person to an uninfected partner during sex. In women the most commonly infected areas are the vulva, vagina, cervix or urethra. In men the most commonly infected area is the penis. During sex, the parasite spreads from one partner to another.  Approximately 70% of infected individuals do not have any signs or symptoms with Trichomoniasis. Symptom intensity can vary from mild irritation to severe inflammation.

Men with trichomoniasis may notice:

  • Itching or irritation inside the penis
  • Burning after urination or ejaculation
  • Discharge from the penis
  • Discomfort with intercourse


Women with trichomoniasis may notice:

  • Itching, burning, redness or soreness of the genitals
  • Discomfort with urination
  • Change in vaginal discharge (thin discharge or increased amount of discharge) that can be clear, white, yellow, green with an unusual fishy smell
  • Discomfort with intercourse


Having trichomoniasis can make it feel uncomfortable to have sex. Without treatment, the infection can last for months or even years. Trichomoniasis can increase the risk of getting or spreading other sexually transmitted infections, including HIV.


Testing for trichomoniasis can be done at Health Center through vaginal swabs for women and urine testing for men. Trich can be treated with oral medications. It is not recommended to drink alcohol while on medication or within 24 hours after taking medication. Individuals who are treated for trichomoniasis can get it again. To avoid getting reinfected, all sexual partners must be treated. An individual should wait 7-10 days after treatment before having sex again.


The only way to avoid trichomoniasis is to not have sex. If you are sexually active, ways to lower your chances of getting trich include being in a long-term mutually monogamous relationship with a partner who has been tested and has negative STD results and by using latex condoms correctly every time you have sex.
