The symptoms of trichomonas vaginitis primarily manifest as an increase in vaginal discharge, itching of the vulva, and burning pain. The discharge in trichomonas vaginitis is usually abundant, sometimes frothy, and can be thin or pus-like, irritating the vulva and vaginal skin, causing mucosal congestion and edema, thus leading to pain. In severe cases, it can cause swelling of the vulva and the urethral opening, as well as symptoms like frequent urination, urgent urination, and painful urination. Trichomonas vaginitis is mostly transmitted directly through sexual intercourse, but it can also be contracted by using public baths, squat toilets, or clothing containing the parasite, although direct transmission through sexual activity is the primary route. Treating trichomonas vaginitis requires oral medication and systemic treatment, and sexual partners must be treated simultaneously. This is because most infected males may not show obvious symptoms, but if left untreated, they can easily cause recurrence and become a significant source of infection.
