For women, contracting trichomonas means getting trichomoniasis vaginitis. The main transmission route of trichomoniasis vaginitis is through sexual intercourse. If there is a history of unprotected sexual activity, it is possible to contract this type of vaginitis. Additionally, going to public baths for showers can also increase the risk of contracting this type of vaginitis. Therefore, if trichomoniasis vaginitis is not completely treated or if personal hygiene is poor, it is very likely to recur. During the first treatment, it is essential to follow the complete course of treatment, using Metronidazole or Tinidazole for seven days. After stopping the medication, a follow-up examination should be conducted after another seven days. If the results are negative in two consecutive follow-up checks, then it is considered cured. However, it is necessary for both male and female partners to undergo treatment simultaneously. If the male partner does not undergo treatment, the infection is likely to recur in the female partner. (Medication should be used under the guidance of a doctor.)
