Rates are based on individual-level case report data of females with primary and secondary syphilis electronically sent to CDC through the National Electronic Telecommunications System for Surveillance (NETSS) and U.S. Census population data. The race categories used in this report were introduced to the NETSS record in 2008. As of 2011, 46 states and the District of Columbia report using the new format. Race and ethnicity will not be displayed until 100% of states report using the new format.
The original baseline was revised from 1.5 to 1.4 due to reporting delays. The target was adjusted from 1.4 to 1.3 to reflect the revised baseline using the original target setting method.
The objective text was revised from "Reduce sustained domestic transmission of primary and secondary syphilis among females" to "Reduce domestic transmission of primary and secondary syphilis among females".
