Trichomonas vaginitis can be completely cured, but it is mostly transmitted through sexual activity. Therefore, both partners must be treated simultaneously during treatment. Oral metronidazole or tinidazole can be taken, and metronidazole can also be placed inside the vagina. Generally, a 7-day course of treatment is sufficient for cure. One week after stopping the medication, a follow-up examination should be conducted, and this should be repeated twice. Only if both results are negative can the cure be considered complete. Males also need to take the medication for at least 7 days, because if a woman is treated and then resumes sexual activity, the male can re-infect the female. (Please use the medication under the guidance of a doctor.)
