Trichomoniasis is a sexually transmitted disease that can be transmitted through sexual contact or through public swimming pools, toilets or hotels. If trichomoniasis is diagnosed, it is best to treat it under medical supervision, usually by treating both husband and wife at the same time, and for men, it is best to take one oral metronidazole tablet in the morning and one in the evening for one week. For women who have no recent fertility requirements and are not virgins, you can douche the vagina with cleanser and use metronidazole vaginal pessary for one week, while taking one oral metronidazole tablet in the morning and one in the evening for one week, and review the leucorrhoea after the next menstrual period. The next menstrual period will be followed by a review of the leucorrhoea. Have sex after the trichomoniasis is cured, otherwise there is a possibility that the inflammation will not be cured.
