Final answer:
Chlamydia is the most prevalent nonviral STD in the US, affecting both males and females, especially among teens and young adults.
Step-by-step explanation:
the most prevalent nonviral sexually transmitted disease (STD) in the United States was Chlamydia. Chlamydia is caused by the bacterium Chlamydia trachomatis. It is a common bacterial infection that can be transmitted through sexual contact.
Chlamydia is known for its high prevalence among sexually active individuals, particularly young adults. It often doesn't cause noticeable symptoms, which can lead to the infection going undetected and untreated, potentially causing complications like pelvic inflammatory disease (PID) in women or epididymitis in men.
