With nearly 400 million new, curable sexually transmitted infections occurring globally each year—a rate of one new case every two seconds—it’s clear that sexual health is a critical public health conversation that demands our immediate attention and understanding.
Key Takeaways
- In 2021, the CDC reported 1,644,613 cases of chlamydia in the United States, with an incidence rate of 497.3 per 100,000 population, disproportionately affecting females aged 15-24 at a rate of 3,460.6 per 100,000
- Globally, WHO estimates 374 million new infections of curable STIs (chlamydia, gonorrhea, syphilis, trichomoniasis) occurred in 2020 among adults aged 15-49, equivalent to one infection every two seconds
- In the US, 2021 CDC data shows gonorrhea cases at 716,870 with a rate of 216.4 per 100,000, rising 28% from 2018-2021, highest among males aged 25-29 at 1,032.4 per 100,000

Sexual health statistics in 2026 highlight both the broad reach of contraception and the continued global impact of STIs. Data across countries shows that contraceptive use remains common, while sexually transmitted infections are still prevalent in many populations.

Single sourceSTIs Prevalence Interpretation
While the world was busy fighting one pandemic, another—composed of chlamydia, gonorrhea, and syphilis—has been raging with a startling new infection every two seconds, disproportionately and relentlessly targeting the young, proving that our collective inattention to sexual health is a crisis loudly begging for us to notice.
