  1. Epidemic CurvesSensitivity/Specificity

  2. Epidemic Curve Number of New Cases Time (since exposure)

  3. Notes on Epidemic Curves • Sort by time to illness • Think critically about the data (possible problems) • Ask questions (or make assumptions) • Similar to Survival Curve (see text, p492)

  4. Survival from AIDS in Mths (p492 in text) Hazard Survival Rate See Table 21.3 in Text (page 493)

  5. Sensitivity/Specificity (p136 in text) • Used in Screening or diagnostic Tests when there is a ‘gold standard’ • Sensitivity: pr(+| ill) • Specificity: pr(-| not ill) • Suppose eating a food item is a ‘test’. If yes, the person should be ill. If no, not ill. • Use ‘symptoms’ as the ‘gold standard’
