Trichomoniasis is a Sexually Transmissible Disease (STD) caused by the protozoan Trichomonas vaginalis. According to a 2005 WHO report, approximately 152 million people worldwide have the disease.

Women may experience symptoms ranging from no vaginal discharge to copious, yellow-greenish, and foamy vaginal discharge, with sensitivity to the vulva and perineum, dyspareunia, and dysuria. A previously asymptomatic infection may become symptomatic at any time, with inflammation of the vulva and perineum and edema of the lips. The vaginal walls and the surface of the cervix may have punctate “strawberry-red” lesions. Urethritis and possibly cystitis can also occur.

Men are usually asymptomatic; but sometimes urethritis results in a secretion that may be fleeting, foamy or purulent, or cause dysuria and polaciuria, usually early in the morning. Often, urethritis is mild and causes only minimal urethral irritation and occasional moisture in the urethral meatus, under the foreskin, or both. Epididymitis and prostatitis are rare complications.

Trichomoniasis is caused by a unicellular protozoan called Trichomonas vaginalis or T. vaginalis, a type of tiny parasite that is transmitted between people during intercourse. The incubation period between exposure and infection can range from five to 28 days.

The treatment of trichomoniasis aims to eradicate the causative agent. The first measure indicated is sexual abstinence, because it is necessary a rebalance of the body to avoid worsening, discomfort and the emergence of new diseases.

It is also indicated the use of antibiotics and chemotherapy, being compulsory the joint treatment of the sexual partner to avoid reinfection. In women, oral treatment is a single dose at the same time as topical treatment with the use of vaginal cream.

Avoid drinking alcohol to prevent nausea and vomiting.
