US STI Rates by the Numbers: A Quiz Based on the Latest CDC Data

Article

SAMPLE: Approximately what percentage of the total US population had an STI at a given point in 2018? Plus 6 more questions on STI trends based on the latest CDC data.

The US Centers for Disease Control and Prevention (CDC) last published estimates of sexually transmitted infections (STIs) in the US in 2008. A new CDC report provides updated estimates for 2018 that shed light on the scope of STIs in the US and what populations are most affected.

Published January 25, 2021 in the journal Sexually Transmitted Diseases, CDC researchers analyzed the prevalence and incidence of 8 common STIs (chlamydia, gonorrhea, trichomoniasis, syphilis, genital herpes, human papillomavirus, hepatitis B, and HIV) in the US in 2018. The 7-question quiz below focuses only on chlamydia, gonorrhea, and syphilis as they are nationally notifiable STIs. Find out the results and key takeaways for primary care in this quick quiz.
