What is Trichomoniasis?

Trichomoniasis is a common sexually transmitted infection (STI) caused by a single-celled parasite called Trichomonas vaginalis. It primarily infects the vagina in women and the urethra in men, though it can sometimes affect other areas.

Symptoms and Diagnosis

Many people with trichomoniasis experience no symptoms. However, when symptoms do appear, women may notice a frothy, yellowish-green vaginal discharge with a strong odor, vaginal irritation, itching, burning during urination, or painful intercourse. Men may experience irritation inside the penis, burning during urination, or a watery discharge. Diagnosis involves a simple test where a sample of vaginal or urethral fluid is examined under a microscope or tested using a nucleic acid amplification test (NAAT).

Treatment and Prevention

Trichomoniasis is easily treatable with a single dose of metronidazole or tinidazole, antibiotics prescribed by a healthcare provider. It’s crucial to abstain from sexual activity until both partners complete treatment to prevent reinfection. Consistent and correct condom use significantly reduces the risk of transmission.

Long-Term Effects

Untreated trichomoniasis can increase the risk of complications, including pelvic inflammatory disease (PID) in women, infertility, and increased risk of HIV transmission. Early diagnosis and treatment minimize these risks. See a doctor if you suspect you might have an STI.
