Notes:

Race or Hispanic Ancestry: Race without mention of Hispanic ancestry, or Hispanic ancestry with or without mention of race.

Due to incomplete reporting of race and Hispanic ancestry, these counts must be considered a minimum. Race and ethnicity reporting has been improving for gonorrhea and chlamydia cases. Completeness of race and Hispanic ancestry data has improved from around 50% in 2005, to 75% in 2014–15, to about 81% in 2018. Reported race and ancestry is nearly complete for syphilis cases ( >95%).
