Trichomoniasis is a common sexually transmitted infection (STI) caused by a tiny parasite called Trichomonas vaginalis.
Trichomoniasis can be difficult to diagnose because there may not be any symptoms, and when there are symptoms, they can be similar to those of other conditions and STIs.
Women are more likely to have symptoms than men. They may have soreness and itching around the vagina and a change in vaginal discharge, while men may experience pain after urination and ejaculation (see Symptoms for further information).

If you are worried you may be at risk of having an STI or have any symptoms (as mentioned on the NHS Choices link to Trichomoniasis), you should visit your local sexual health or GUM clinic to have them checked out.
