Doctor's Notes on Trichomoniasis
Trichomoniasis (commonly referred to as trich) is a common sexually transmitted disease. It is caused by an infection with the parasite known as Trichomonas vaginalis. In women it affects the vagina, vulva, urethra, or cervix. In men, trichomoniasis affects the urethra in the penis.
Trichomonas infection may not cause any symptoms or signs, but if a person has the infection, they can still spread it to other people even if they do not have symptoms themselves. When the condition does cause signs and symptoms, the associated symptoms and signs include redness, burning, and itching of the genital areas, pain with urination (dysuria), and an abnormal vaginal or penile discharge that has been described as foul-smelling and gray, green, yellow, or white in color.
What Is the Treatment for Trichomoniasis?
The treatment of trichomoniasis involves the drug metronidazole or tinidazole. These drugs are effective at getting rid of the infection. Both drugs are usually taken in pill form in a single dose. It is important for all sex partners of an affected person to be treated, because the infection can return or be spread to others. After the infection is cured, it is possible to develop trichomoniasis again if you are exposed.
