Trichomoniasis is a sexually transmitted infection caused by the parasite Trichomonas vaginalis.
Infection occurs during sexual intercourse without a condom. It is more common in young people and in people with multiple sexual partners.
In most cases, there are no symptoms. In case of symptoms, they usually occur between 5 and 28 days after unprotected sexual intercourse with the infected person. In women it is usually in the form of changes in vaginal discharge; increased discharge with a strong fishy odor is very characteristic. It may be accompanied by vaginal discomfort or itching during urination. In severe cases, the infection may spread to the tubes that connect the ovaries to the uterus, the fallopian tubes. This infection is called salpingitis and causes pain in the lower abdomen.
Diagnosis is based on medical questioning and gynecological examination. A sample from the genital area is needed for confirmatory diagnosis. Tests for other sexually transmitted infections should also be performed, as it is not uncommon to have more than one infection at a time.
Antibiotic treatment should be given to both symptomatic and asymptomatic individuals; Metronidazole or Tinidazole is often used orally for one week. Sexual partners should also be treated.
