Trichomonas vaginitis / urogenital infection

At a Glance

A urogenital infection caused by Trichomonas vaginalis, including trichomonal vaginitis.

In women, yellowish-green or gray vaginal discharge, vaginal odor, discomfort during intercourse, dysuria, itching, or burning may occur.

How the disease works

The cause is the parasite Trichomonas vaginalis, which is primarily transmitted between humans through sexual contact.

Parasitic infection in the urogenital tract can cause localized inflammation and symptoms related to discharge and urination.

Variations in presentation among individuals

Sexual contact status and pregnancy status can affect clinical significance, and there is a large difference between asymptomatic and symptomatic individuals even when infected.

The broad framework of diagnosis and management

Many people are asymptomatic, and if symptoms occur, they typically begin within 5–28 days after infection.

Diagnosis is not confirmed based on clinical symptoms alone but centers on laboratory tests to confirm infection.

Current status of treatment

Since asymptomatic infections are common, the absence of symptoms alone cannot rule out infection, and other diseases may present with similar symptoms.

The core of management involves confirming infection through testing, administering antibiotic treatment, and considering the evaluation and treatment of sexual partners concurrently.

The MedlinePlus overview presents antibiotics as the treatment for trichomoniasis.

How to read clinical trials

ClinicalTrials.gov contains records of related intervention studies, but efficacy, safety, or whether they constitute standard treatment cannot be determined solely by registration status or the fact of completion.

Points to verify during clinical consultations

In clinical practice, it is possible to confirm symptoms and onset time, recent sexual contact and whether partners have been tested/treated, possibility of pregnancy, drug allergies, and possibility of re-exposure.
