Which of the following terms refers to the most common bacterial STI?

Chlamydia is recognized as the most common bacterial sexually transmitted infection (STI) globally. It is primarily caused by the bacterium Chlamydia trachomatis and often goes undiagnosed because individuals may not exhibit symptoms. This silent nature of the infection contributes to its high prevalence, as many people remain unaware they are infected and can unknowingly transmit the bacterium to others.

In contrast, while gonorrhea is also a common bacterial STI, its incidence is lower than that of chlamydia. Syphilis and trichomoniasis, although they are significant STIs, do not match the prevalence of chlamydia. The awareness and screening for chlamydia have increased in recent years, which may further account for its identification as the most common bacterial STI.
