Trichomonal vaginitis typically presents clinically with watery, foul-smelling, and frothy vaginal discharge, generally accompanied by itching that worsens at night. At this time, it is advisable to visit a hospital to get a secretion test to confirm the diagnosis. If it is a trichomonas infection, treatment can be administered according to the symptoms of trichomonal vaginitis. Normally, female vaginal discharge is clear, transparent, odorless, and in small amounts, which is considered normal. If a trichomonas infection occurs, symptomatic treatment usually leads to improvement within a week. Therefore, patients with trichomonal vaginitis must go to the hospital for a secretion test and then choose the appropriate medication based on the test results for symptomatic treatment. It is also crucial to maintain hygiene of the external genitalia to prevent infection, and inflamed conditions should be treated promptly.
