Explanation:

🆕 New Concept Discovered: Sexually Transmitted Infections (STIs)
Identifying pathogens and prevalence of common infections.

Step 1: Distinguish between bacterial and viral STIs

To answer the question, we first need to identify which of the options are caused by bacteria:

• Chlamydia is caused by the bacterium Chlamydia trachomatis.
• Gonorrhea is caused by the bacterium Neisseria gonorrhoeae.
• Syphilis is caused by the bacterium Treponema pallidum.
• Genital herpes is caused by the herpes simplex virus (HSV), meaning it is a viral infection, not bacterial.

Step 2: Compare prevalence rates in the United States

According to data from the Centers for Disease Control and Prevention (CDC):

• Chlamydia is the most commonly reported bacterial STI in the United States, with over 1.6 million cases reported annually.
• Gonorrhea is the second most common bacterial STI.
• Syphilis is significantly less common than both chlamydia and gonorrhea.

Therefore, chlamydia is the most prevalent bacterial STI in the United States.

a) chlamydia
