  1. Sexually Transmitted Disease (STD) Surveillance Report, 2007 Minnesota Department of Health STD Surveillance System www.health.state.mn.us/std

  2. Introduction • Under Minnesota law, physicians and laboratories must report all laboratory-confirmed cases of chlamydia, gonorrhea, syphilis, and chancroid to the Minnesota Department of Health (MDH) within one working day. • The MDH does not maintain statistics for other, non-reportable STDs (ex: herpes, HPV/genital warts). • This slide set describes trends in reportable STDs in Minnesota by person, place, and time. • Analyses exclude cases reported from federal and private prisons. STDs in Minnesota: Annual Review

  3. Introduction • STD surveillance is the systematic collection of data from cases for the purpose of monitoring the frequency and distribution of STDs in a given population. • STD surveillance data are used to detect problems, prioritize resources, develop and target interventions, and evaluate the effectiveness of interventions. STDs in Minnesota: Annual Review

  4. Interpreting STD Surveillance Data • Factors that impact the completeness and accuracy of STD data include: • Level of STD screening by healthcare providers • Individual test-seeking behavior • Sensitivity of diagnostic tests • Compliance with case reporting • Completeness of case reporting • Timeliness of case reporting • Increases and decreases in STD rates can be due to actual changes in disease occurrence and/or changes in one or more of the above factors. STDs in Minnesota: Annual Review

  5. Interpreting STD Surveillance Data • The surveillance system only includes cases diagnosed in conjunction with a positive laboratory test. Cases diagnosed solely on symptoms are not counted. • Surveillance data represent cases of infection, not individuals. A person with multiple infections in a given year will be counted more than once. • Caution is warranted when interpreting changes in STD numbers that can seem disproportionately large when the number of cases is small.
