The disease remains far less common than before penicillin, but rates have climbed annually since 2000–2001, and certain groups face disproportionate risk.

Tracking syphilis prevalence matters because this bacterial STI is curable with penicillin, yet untreated infections can cause severe neurological, cardiovascular, and reproductive complications. Prevalence data help public health agencies target testing and treatment to communities most affected. Syphilis can also increase HIV transmission risk, making surveillance a key part of broader sexual health efforts. Rates vary sharply by geography, race, and behavior, so broad averages hide important disparities.
