What is the most common cause of non-gonococcal urethritis?

Gonorrhea
Chlamydia
Trichomonas
Herpes

The correct answer is: Chlamydia

The most common cause of non-gonococcal urethritis is Chlamydia. This sexually transmitted infection is caused by the bacterium Chlamydia trachomatis and is a prevalent pathogen in cases of urethritis that is not attributable to gonorrhea. Non-gonococcal urethritis encompasses a group of infections that can be caused by various pathogens, but Chlamydia is responsible for the majority of these cases due to its high incidence rate in sexually active populations. Furthermore, Chlamydia can often present asymptomatically, meaning many individuals may not realize they are infected, leading to a higher overall prevalence in the population compared to other pathogens that cause urethritis. Other causes of non-gonococcal urethritis, such as Trichomonas or herpes, are less frequently encountered when compared to infections caused by Chlamydia. Thus, focusing on Chlamydia as the leading cause is vital in clinical assessment and management of non-gonococcal urethritis.
