Sexually Transmitted Disease

Sexually transmitted disease (STD) statistics on PeriStats were obtained from Division of STD Prevention (DSTD), National Center for HIV, STD, and TB Prevention (NCHSTP), Centers for Disease Control and Prevention (CDC). They acquire this data from STD control programs and health departments in the 50 States, the District of Columbia, selected cities, counties, U.S. dependencies and possessions, and independent nations in free association with the United States. Rates for chlamydia, gonorrhea, and syphilis are reported as rates per 100,000 women. Congenital syphilis is reported as a rate per 100,000 live births. Rates for syphilis and congenital syphilis are 5-year averages. More background can be found at the DSTD Web site.
