Question

The most common sexually transmitted infection in the United States is:

1) gonorrhea.
2) syphilis.
3) chlamydia.
4) trichomoniasis.

Answer 1

The most common STI in the United States is the human papillomavirus (HPV), with chlamydia being the most prevalent bacterial STI. While bacterial STIs can be treated with antibiotics, HPV and other viral infections generally cannot be cured.

Step-by-step explanation:

The most common sexually transmitted infection (STI) in the United States is not chlamydia, gonorrhea, or syphilis, but rather infection with the human papillomavirus (HPV). While chlamydia is the most common bacterial STI in the U.S., with high rates particularly among females and teens, HPV surpasses it with an estimated 80 million Americans infected and about 14 million new infections each year. HPV is so prevalent that nearly all sexually active individuals will acquire it at some point in their lives. Unlike bacterial STIs such as chlamydia, gonorrhea, and syphilis, which can typically be cured with antibiotics, most viral infections like HPV are incurable, posing a risk of persistent sexual transmission.
