Trichomonas symptoms and how it's caught
Quick links on this page:
Symptoms of trichomonas infection
Almost half of all people with trichomonas infection will have no symptoms.
If symptoms are present, these usually include a yellow or green discharge from the penis or vagina, which can sometimes have an unpleasant, ‘fishy’ smell.
You may have pain or a burning sensation when peeing, or itching and soreness in the genital area.
Women may also experience pain or discomfort during sex.
If you think you or your partner may have a trichomonas infection, it's important to get tested.
How trichomonas infection spreads
You can catch trichomonas infection by having unprotected sex, or sharing sex toys.
Because many people have no symptoms and do not know they have a trichomonas infection, you or your partner could have picked up the infection from a previous partner without even knowing it.
Avoiding trichomonas infection
The best way to prevent all sexually transmitted infections including chlamydia, as well as to protect against HIV, is to practice safer sex.
This means using a condom for vaginal, oral or anal sex.
