Trichomoniasis symptoms

Trichomoniasis is a common STI caused by a microscopic, one-celled parasite called Trichomonas vaginalis. This organism spreads during sexual intercourse with someone who already has the infection.

The organism usually infects the urinary tract in men, but often causes no symptoms. Trichomoniasis typically infects the vagina in women. When trichomoniasis causes symptoms, they may appear within five to 28 days of exposure and range from mild irritation to severe inflammation.

Signs and symptoms may include:

• Clear, white, greenish or yellowish vaginal discharge
• Discharge from the penis
• Strong vaginal odor
• Vaginal itching or irritation
• Itching or irritation inside the penis
• Pain during sexual intercourse
• Painful urination
