* Per 100,000 population

† Total includes cases reported with unknown sex.

NOTE: These tables should be used only for race/Hispanic ethnicity comparisons. Cases in the 0–4 age group may include cases due to perinatal transmission. No population data exist for unknown sex, unknown age, or unknown race; therefore, rates are not calculated. Cases and rates shown in this table include District of Columbia but exclude US territories. See Technical Notes for more information on chlamydia case reporting and on collection of race and Hispanic ethnicity for STI case data. This report includes data from years that coincide with the COVID-19 pandemic, which introduced uncertainty and difficulty in interpreting case data. See Impact of COVID-19 on STIs for more information.
