Application of an Epi Profile: Gonorrhea in the U.S. Region V Gonorrhea Control Meeting

What is an epi profile? Standardized way to analyze & interpret data Standardized way to analyze & interpret data Suggested, not required Suggested, not required Provides evidence to support public health decision-making Provides evidence to support public health decision-making Supplement to classroom & on-the-job training Supplement to classroom & on-the-job training Provides a common language for communication with other public health programs Provides a common language for communication with other public health programs

Why do we need an STD epi profile? High burden of disease High burden of disease Insufficient funding for unlimited program activities Insufficient funding for unlimited program activities Few opportunities for classroom or on-the-job training experiences Few opportunities for classroom or on-the-job training experiences Technological advances allowing for more sophisticated analysis of data Technological advances allowing for more sophisticated analysis of data

Summary: Gonorrhea from a National Perspective Concentrated in South Select, not all, counties Shift towards private sector Adolescents/young adults African Americans Heterosexual AND MSM Increases in test volume Persistent racial disparities Association with high risk behaviors Persistent high rates of gonorrhea

“Heterosexual men and women with GC tend to be younger and African American, and to have minimal risk behaviors other than more than one partner. In contrast, MSM with GC reported a greater number of sex partners, more sex with anonymous partners, more sex with partners met on the internet, and more frequent drug use. Such data suggest two markedly different GC epidemics among heterosexuals and MSM.” Rietmeijer, et al, ‘Here Comes the Ssun’; PH Reports 2009 Supp. 2.; V. 124
