Highlights
There were more than 2.4 million STIs reported in the United States in 2023; however, there are promising signs the epidemic may be slowing:
- Gonorrhea dropped for a second year—declining 7% from 2022 and falling below pre-COVID-19 pandemic levels.
- Overall, syphilis increased by only 1% after years of double-digit increases.
- Primary and secondary syphilis declined for the first time in more than two decades, down 10% since 2022. These cases also dropped 13% among gay and bisexual men for the first time since CDC began reporting national trends among this group in the mid-2000s.
- Increases in congenital syphilis cases appear to be slowing in some areas—with a 3% increase over 2022 nationally, compared to 30% annual increases in prior years.
While these data are encouraging, reportable STIs remain unacceptably high and disparities persist.
