Yes, in the case of diagnosis of Trichomonas vaginalis, treatment should be followed by all partners. This is the only way to heal properly, without the risk of recurrence. The vagina is the most frequent site of infection in a woman, while in a man it is the urethra. If the infection is neglected, the Trichomonas can travel up the genital tract, infecting the urinary tract. It is one of the most common sexually transmitted diseases contracted through unprotected sex. An infant can be infected during childbirth. 

Infection can often be asymptomatic, especially in boys. In girls, however, infection occurs with intense itching, local burning, redness of the vulva and vagina and yellowish-green discharge that is frothy and bad-smelling. It is also associated with pain during sexual intercourse (dyspareunia) and burning during urination.

Healing can be quick if the treatment is done right away. There is a specific drug that needs to be taken orally for treatment. The treatment should be followed by all partners at the same time to avoid any reinfection. During treatment, consumption of alcohol is not advisable, as it may greatly increase instances of nausea or vomiting.
