EARLY LOCALIZED: erythema migrans at bite site 7-14 days after tick detachment, usually round or oval (annular). EARLY DISSEMINATED: secondary skin lesions look like erythema migrans but scattered and smaller. Flulike symptoms LATE DISSEMINATED: Px & joint swelling. Migratory arthralgias from days - months. Affects knees & hips, knee swelling can occur & Baker cysts. - SXS at each stage of Lyme disease (borrelia burgdorferi) Just remember what this looks like - -Select surveillance methodology -Asses and define population(s) to be studied -Choose events to monitor -Determine time period for observation -Identify surveillance criteria (case definition) -Identify data elements to be collected -Determine methods for data analysis -Determine methods for data collection and management -Design an interpretive surveillance report -Identify recipients of the surveillance report -Develop a written surveillance plan -Surveillance program evaluation - Elements of an effective Surveillance Program Platykurtic is (-) SHORTEST & FLAT Mesokurtic (normal aka 0) Leptokurtic (+) TALLEST & POINTY - Which one is which? separate newborn from mother temporarily, feeds should be done by healthy caregiver; Do not need to wear mask during labor ; wear mask to hold newborn; 3 ft distance - What needs to happen if a mother giving birth is influenza + ?

Determines whether two sample means calculated are different in case of standard deviation - What does a Z-Test do? 1. Strength of Association 2. Consistency 3. Specificity - ideally, effect has only one cause 4. Temporality - Cause should be present before the effect occurs 5. Biological gradient- dose response between risk factor and the effect 6. Biological plausibility- Rational and theoretical basis how or why risk factor led to effect 7. Coherence- Association should not conflict with known facts 8. Experimental evidence 9. Analogy- Previously accepted phenomenon in one area can be applied to another - Hill's Criteria for Causation Spec:If someone doesn't have the outcome what's the likelihood of test being negative?
