Trichomoniasis is a common STI caused by a parasite. In women, trichomoniasis can cause a foul-smelling vaginal discharge, genital itching and painful urination. Men who have trichomoniasis might experience a burning sensation while urinating. According to the CDC in 2018, there were more than 2 million trichomoniasis infections, however only about 30% developed any symptoms
Causes
Trichomoniasis is caused by a parasite called Trichomonas vaginalis. In women this parasite mainly infects the vagina and the urethra. In men the infection most commonly affects the urethra, but can sometimes infect the prostate gland. The parasite is usually spread by having intercourse without using a condom.
You cannot share trichomoniasis through:
- kissing or hugging
- sharing cups, plates or silverware
- toilet seats
The safest way to prevent getting any STI is abstinence, however if that is not an option then you can lower your risk by wearing a condom and limiting your number of partners
Treatment
Trichomoniasis will usually not go away without treatment, however it can be treated with antibiotics. The entire time that one is infected with trichomoniasis, you can spread it to any partners, so it is important that you inform your partner so both of you can be treated.
Your healthcare provider will most likely prescribe metronidazole, however they might also prescibe tinidazole. Women are usually prescribe metronidazole for seven days, an men are prescribed a single dose of the same medication
Unless both you and your partner are treated, you will pass it back and fourth. Having intercourse within one week could be too soon and as a result could cause reinfection. You should return to your healthcare provider 3 months later to ensure you do not have the infection anymore.
