The lower genital tract is infected by the parasite. The urethra, vagina, uterine hole (cervix), and outside portion of the genitalia (vulva) all belong to women. The parasite affects men by infecting the urethra, or interior of the penis.

Treating trichomoniasis has the same approach like what's is done with other STDs. All sexual partners of the index needs treatment to avoid reinfection. Offering treatment to just one person is total pointless because they will get it from the source again. 

A drug called metronidazole commonly (flagyl) is an effective treatment of trichomoniasis. Alternatively the following drugs are also used for treatment: 

  • Secnidazole
  • Tinidazole

Treatment can be given in two options namely using high dose or normal multiple doses

High dose:  A patient takes 2g once per oral of metronidazole or the other drugs above accordingly.
