* The case classification of ‘Unknown duration or late syphilis’ went into effect in January 2018. During 2014–2017, cases in this category include cases classified as late latent syphilis and late syphilis with clinical manifestations. See Appendix A1.9 for a detailed explanation of changes to the syphilis case definition.

† MSAs were selected on the basis of the largest population in the 2010 US Census.

‡ 2016 county data for Alabama have been corrected and may not match previous reports.

§ The variable used to identify county, which is used to classify cases into MSAs, was complete for <95% of cases in a state contributing data to this MSA. See Section A1.4 in the Appendix for more information.
