Sexually Transmitted Disease Surveillance 2017 presents statistics and trends for STDs in the United States through 2017. This annual publication is intended as a reference document for policy makers, program managers, health planners, researchers, and others who are concerned with the public health implications of these diseases. The figures and tables in this edition supersede those in earlier publications of these data.

The surveillance information in this report is based on the following sources of data: (1) notifiable disease reporting from state and local STD programs; (2) projects that monitor STD positivity and prevalence in various settings, including the National Job Training Program, the STD Surveillance Network, and the Gonococcal Isolate Surveillance Project; and (3) national surveys and other data collection systems implemented by federal and private organizations.

Four STDs are nationally notifiable, chlamydia, gonorrhea, syphilis, and chancroid, and state and local STD control programs provide CDC with case reports for these conditions. These case reports are the data source for many of the figures and most of the statistical tables in this publication; however, it is important to note that these case reports reflect only a portion of STDs occurring in the US population. First, other common STDs, such as human papillomavirus (HPV) and herpes simplex virus (HSV) are not nationally notifiable diseases. Additionally, STDs are often asymptomatic and may not be diagnosed; therefore, case report data underestimate the number of infections that occurred.

Sexually Transmitted Disease Surveillance 2017 consists of four sections: the National Profile, the Special Focus Profiles, the Tables, and the Appendix. The National Profile section contains figures that provide an overview of STD morbidity in the United States. The accompanying text identifies major findings and trends for selected STDs. The Special Focus Profiles section contains figures and text that describe STDs in selected populations that are a focus of national and state prevention efforts. The Tables section provides statistical information about STDs at county, metropolitan statistical area, regional, state, and national levels. The Appendix includes information on how to interpret the STD surveillance data used to produce this report, as well as information about Healthy People 2020 STD objectives and progress toward meeting these objectives, Government Performance and Results Act goals and progress toward meeting these goals, and STD surveillance case definitions.
