Trichomoniasis is the most common curable STI in the United States, yet it is often excluded from standard STI screenings. This omission is perplexing, but not surprising. So let’s dig into this subject so you can better advocate for your sexual health.
What Is Trichomoniasis?
Trichomoniasis is a sexually transmitted infection caused by the protozoan parasite Trichomonas vaginalis. It primarily affects the urogenital tract, resulting in symptoms like itching, burning, redness, and unusual discharge. Interestingly, many people infected with trichomoniasis remain asymptomatic, making it easier for the infection to spread unknowingly.
The Prevalence of Trichomoniasis
According to the Centers for Disease Control and Prevention (CDC), an estimated 3.7 million people in the United States have trichomoniasis, but only about 30% develop symptoms. The high rate of asymptomatic cases contributes to its spread, as many individuals are unaware they carry the infection.
The Life Cycle of this Parasite
The life cycle of this parasite involves a single stage—the trophozoite stage—during which the organism exists as a pear-shaped, flagellated cell. Unlike many other parasites, Trichomonas vaginalis does not have a cyst stage in its life cycle. It reproduces through a process known as binary fission, where a single organism divides into two genetically identical cells. This process allows the parasite to multiply rapidly within the host’s urogenital tract.
Trichomonas vaginalis feeds primarily on bacteria and organic matter in the host’s urogenital environment. It attaches to the epithelial cells lining the urogenital tract and ingests nutrients through a specialized feeding structure called the cytostome. This feeding process can lead to tissue damage and inflammation, manifesting in symptoms such as discharge, itching, and discomfort.
The Inadequacies of Current STI Panels
One of the significant issues with STI testing today is that trichomoniasis is frequently excluded from standard STI panels.
