Trichomoniasis: The Most Common, Curable STI

Just when you thought you knew about every STI in the book, trichomoniasis shows up. Trichomoniasis or "trich" is found more often in women than men, but affects both sexes. Caused by a parasite passed during vaginal intercourse, like most STIs, it's usually preventable with proper protection. Carriers of trich typically show very few symptoms. Women who do show symptoms will usually notice them within five to 28 days after exposure.


  • Reddening of the vagina or vulva
  • Frothy, green or yellow vaginal discharge.
  • Itching
  • Fishy odor
  • Discomfort during sex and/or urination

To learn about the complications of this STI and treatment please


Complications: While trich is not a dangerous or life-threatening infection, it can lead to an increased risk of both HIV and genital herpes and a higher rate of PID and preterm births in pregnant women.

Treatment: To test for trich, your gynecologist will perform a physical exam and have lab-work done. Should the diagnosis be positive, you'll be prescribed an oral drug.

Dear's Advice: Although trich may be considered a minor STI compared to herpes and HIV, it's important to recognize that it comes with its own set of concerns and should be treated as soon as possible. As with all STIs, using a condom will greatly reduce your chances of infection.
