Document Summary
Attack rate: a mathematical approach to determine the percentage of individuals infected by a specific variable. Relative risk: can be defined as the risk of sickness when comparing two opposing variables (those who did and those who did not) Potato fries: total that ate: 422 infected: 184. Therefore, 43. 6% of people became ill after eating potato fries. Potato fries: total that did not eat 152 infected: 46. Therefore, 30. 3% of people became ill after eating potato fries. Therefore, people who ate potato fries were 1. 4x more likely to become ill than non-potato fry eaters. Molecular epidemiology focuses on how genetics contributes to disease risk and help identify the biological markers that are associated with exposure. Clinical epidemiology focuses on enhancing clinical decisions to benefit an individual"s health compared to improving the health of the population. What, who, where, when, and why with regards to illness or outbreak.
