Trichomoniasis vaginitis is caused by Trichomonas vaginalis. The main symptoms include increased vaginal discharge and vulvar itching, and may also involve burning, pain, and painful intercourse. The characteristic symptom of the vaginal discharge is thin, purulent, yellow-green, and foamy with a foul odor. Trichomoniasis vaginitis is primarily transmitted through sexual intercourse, though occasionally it can be transmitted via public baths, bathtubs, towels, swimming pools, toilets, contaminated clothing, and appliances used on the face, etc. Generally, males do not exhibit symptoms. Regardless of the severity, it is advisable to go to the hospital for active, systematic, and correct treatment for trichomoniasis vaginitis. Under a doctor's advice, some antitrichomonal medications can be used. Treatments may include oral administration, intravenous infusion, or local medication, as well as vulvar itching treatments or vulvar cleansing, etc. It is important to note that the sexual partner must be treated simultaneously to prevent cross-infection. Moreover, to avoid reinfection, the underwear of both the female and her sexual partner, as well as their bathing towels, should be boiled for more than ten minutes to eradicate the pathogens. For detailed information, it is best to adhere to the doctor's instructions and proper diagnosis.
