Trichomoniasis is the most common non-viral sexually transmitted disease (STD) in the world. Most people call the condition 'trich'. Its name comes from the parasite Trichomonas vaginalis that causes the disease.
Causes of Trichomoniasis
A parasite called Trichomonas vaginalis causes this STD. Once you’re infected, you can give trich to someone else through:
Vaginal-penile or vaginal-vaginal intercourse.
Genital touching (skin-to-skin contact without ejaculation).
Symptoms of Trichomoniasis
Thin (or sometimes foamy) white, yellow or greenish vaginal discharge that has a bad odor.
White discharge from the penis.
Genital itching or irritation.
Burning or painful urination.
Burning after ejaculation.
Pain or discomfort during intercourse.
Diagnosis of Trichomoniasis
For women, this exam includes a pelvic exam.
Your healthcare provider examines a sample of the genital discharge under a microscope to check for signs of infection. The vaginal swab collected may be sent to the lab for further testing if trichomonads are not seen under the microscope.
Treatment of Trichomoniasis
Oral anti-infective medications kill trich. Your healthcare provider may prescribe metronidazole (Flagyl) or tinidazole (Tindamax). It’s important to keep the following points in mind while undergoing treatment:
A single medication dose cures up to 95% of infected women. Men and women may need to take the medication for five to seven days.
You and your sexual partners must be treated for trich or you will continue to pass the infection back and forth.
You shouldn’t have sex for one week after finishing the medication to give the drug time to kill off the infection and for symptoms to clear up. Having sex too soon can lead to reinfection.
You should see your healthcare provider in three months to ensure you’re no longer infected.
