Figure 25. Primary and secondary syphilis - Reported cases by reporting source: United States, 1984-2004

Note: Prior to 1996, the STD clinic source of report corresponded to public (clinic) source of report, and the non-STD clinic category corresponded to private source of report. See Appendix (Reporting Sources, Table A2). After 1996, as states began reporting morbidity data electronically, the specific source of report (i.e., STD clinic) began to be reported from an increasing number of states.

Figure 26. Primary and secondary syphilis - Rates: United States, 1970-2004 and the Healthy People 2010 target


Note: The Healthy People 2010 target for P&S syphilis is 0.2 case per 100,000 population.

Figure 27. Primary and secondary syphilis - Rates by state: United States and outlying areas, 2004


Note: The total rate of P&S syphilis for the United States and outlying areas (Guam, Puerto Rico and Virgin Islands) was 2.8 per 100,000 population. The Healthy People 2010 target is 0.2 case per 100,000 population.

Figure 28. Primary and secondary syphilis - Rates by county: United States, 2004


Note: The Healthy People 2010 target for P&S syphilis is 0.2 case per 100,000 population. In 2004, 2,488 (79.3%) of 3,139 counties in the U.S. reported no cases of P&S syphilis.

Note: The surveillance case definition for congenital syphilis changed in 1988. See Appendix (Congenital Syphilis Morbidity Reporting). Case counts for congenital syphilis shown in this graph correspond to those listed in Table 39.

Note: The Healthy People 2010 target for congenital syphilis is 1.0 case per 100,000 live births. The surveillance case definition for congenital syphilis changed in 1988. See Appendix (Congenital Syphilis Morbidity Reporting).
