During the treatment of trichomonas vaginitis, it is necessary to maintain the cleanliness of the vulva to prevent secondary bacterial infections. Clean the vulva daily, change underwear frequently, and avoid eating spicy foods and drinking alcohol during the acute phase. Sexual activities should be prohibited during the treatment period. After the treatment, it is important to promptly check for trichomonas negativity. Treatment should continue for one more course after the next menstrual period is clean, and vaginal discharge should be re-examined after each menstrual period; only after three negative results can it be considered cured. Additionally, attention should be paid to avoiding reinfection during treatment. Underwear and towels used for washing should be boiled for five to ten minutes to eliminate pathogens, which is crucial for the radical cure of trichomonas vaginitis.
