To answer your question, we can look into the data regarding sexually transmitted infections (STIs) in the United States.

1. Chlamydia: It has historically been reported as the most common STI in the U.S. According to the Centers for Disease Control and Prevention (CDC), chlamydia consistently has the highest number of reported new cases each year.

2. Gonorrhea: Although gonorrhea rates have been increasing, the number of new cases is still lower than that of chlamydia.

3. HPV (Human Papillomavirus): HPV is exceedingly common, but most cases are not reported in the same manner as other STIs because many individuals are asymptomatic.

4. Syphilis: While there has been an uptick in syphilis cases in recent years, the total number is still not as high as that of chlamydia.

Based on the current statistics, chlamydia is the STI that represents the highest number of new cases in the United States.
