Trichomoniasis is the most common curable STDs. Millions of people are infected each year in the United States.

Symptom Overview

Trichomoniasis (also called Trich) is a common sexually transmitted disease that is easy to cure. The infection often has no symptoms although women are more likely than men to get symptoms. Pregnant women with trichomoniasis can deliver premature, low birth weight babies.
If symptoms are present, they usually develop one week to one month after infection


  • Foul smelling white, gray, yellow or green colored vaginal discharge
  • Genital redness, burning and itching
  • Pain with urination or sexual intercourse
  • Symptoms may get worse during menstruation


  1. Itching or irritation inside the penis
  2. Burning after urination or ejaculation
  3. Some discharge from the penis


In 2008, there were over 3.7 million estimated new and existing cases of Trichomoniasis in the US. Trichomoniasis is the most common curable STD in young, sexually active women.


Trichomoniasis is spread through body fluids during unprotected vaginal, or anal sex.


Review of symptoms is not sufficient enough to diagnosis Trichomoniasis. It is usually diagnosed by microscopic examination of discharge fluid taken from the vagina. A molecular (nucleic acid) laboratory test for trich is also available. In men, trich infection is difficult to diagnose – it can sometimes be seen on a microscopic examination of urine.


Trichomoniasis can be cured with oral antibiotic medication such as metronidazole or tinidazole. Drinking alcohol while taking these medications can cause severe nausea and vomiting.

Living with It

Most trichomoniasis infections are easily cured with oral medication. However, many women are re-infected from an untreated male partner, so partners should also be treated even if they don’t have any symptoms. Recurrent or persistent trich infections may require re-treatment with extended courses of antibiotic medication.
