Trichomoniasis is a sexually transmitted infection caused by a parasite. It infects the vagina in women, or the urethra in men. Trichomoniasis is one of the most common causes for vaginitis in women.
Trichomoniasis is spread through body fluids during unprotected vaginal, or anal sex.
Most people are not aware that they have the infection — especially men. When women have symptoms, they may be
- -frothy, bad-smelling discharge
- -yellow or green discharge
- -itching in and around the vagina
- -swelling in the groin the
- -urge to urinate frequently — often with pain and burning
- Men rarely have symptoms. When they do, they may have:
- -discharge from the urethra
- -the urge to urinate frequently — often with pain and burning
If you’re a woman, your health care provider will give you a usually painless pelvic exam to take a sample of your vaginal discharge.
If you’re a man, your health care provider will take a swab of your urethra to get a sample of the discharge. A clinician will prescribe you antibiotic pills. To keep from infecting your partners, you should avoid sex until you have taken all the antibiotics and your partner has been tested and treated if necessary.
