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). After 1996, as states began reporting morbidity data electronically, the specific source of report (i.e., STD clinic) became available from an increasing number of states.
