NOTE: These tables should only be used for race/ethnicity comparisons. See Table 34 for age-specific cases and rates and Tables 26-28 for total and sex-specific cases and rates.

Cases in the 0–4 and 5–9 age groups may include cases due to congenital transmission.

In 2011, race/ethnicity was unknown (i.e., unknown, missing, or invalid data values) for 2.9% of reported primary and secondary syphilis cases.

No population data are available for unknown sex and age; therefore, rates are not calculated.
