* Per 100,000. † Total includes cases reported with unknown sex. NOTE: These tables should be used only for race/Hispanic ethnicity comparisons. See Table 15 for age-specific cases and rates and Tables 14, 14A, and 14B for total and sex-specific cases and rates. Primary and secondary syphilis reported among children aged 0–4 may represent the misclassification of congenitally-acquired syphilis. Cases reported as congenitally-acquired syphilis (congenital syphilis) can be found in Table 20. No population data exist for unknown sex, unknown age, or unknown race; therefore rates are not calculated. The COVID-19 pandemic has introduced uncertainty and difficulty in interpreting STD data collected during 2020 and 2021. See Impact of COVID-19 on STDs for more information. |
