1. Epidemiology: study of the occurrence, distribution, and determinants of health and disease in
populations
2. Public health: health of a population as a whole
3. Disease surveillance: the observation, recognition, and reporting of diseases as they occur
4. Incidence: number of new cases
5. Prevalence: total number of new and existing disease cases
6. Descriptive epidemiology: data about infected people are collected and analyzed
(exploratory study)
-> identification of patterns
7. Experimental epidemiology: controlled experiments designed to test hypotheses
(causative and treatments) - animal models / humans
8. Analytical epidemiology: gathers data from selected group of individuals -> case of the
disease and risk factors
9. Retrospective: gather data from the past
10. Prospective: gather data as events unfold
11. Cohort studies: studies group of individuals that share a characteristic
12. Case-control studies: compare healthy vs diseased individuals
13. Cross-sectional study: randomly selected individuals and compared for specific
characteristics
14. Sporadic: occurs occasionally
15. Endemic: a disease constantly present in a population, in low numbers
16. Epidemic: simultaneously infects an unusually high number of individuals in a population
17. Pandemic: worldwide epidemic disease
18. Mortality: incidence of deaths in a population
19. Morbidity: incidence of disease in a population and includes both fatal and nonfatal
diseases
20. Disability-adjusted life year (DALY): cumulative number of years lost due to illness,
disability, or
premature death
21. Herd immunity: resistance of a population to a pathogen as a result of the e portion
