Across
- 3. an association between an exposure and health outcome that varies in a consistently increasing or decreasing fashion as the amount of exposure increases
- 4. a disease that by law must be reported to public health authorities upon diagnosis
- 7. a line graph that begins w/ 100% of the study population and displays the percentage of the population still surviving at successive points in time; can also be used to depict freedom from a health problem, complication, or another endpoint
- 9. the ability of an agent to cause disease after infection, measured as the proportion of person infected by an agent who then experience clinical disease
- 11. an inanimate object that can be the vehicle for transmission of an infectious agent
- 14. any of a group of viruses that are transmitted between hosts by mosquitoes, ticks, and other arthropods
- 17. systematically tabulated data about recorded births, marriages, divorces, and deaths
- 20. the observation that employed persons generally have lower mortality rates than the general population, because persons with severe, disabling disease who have higher mortality rates tend to be excluded from the workforce
- 22. a visual display of the geographic pattern of a health problem, in which a marker is placed on a map to indicate where each affected person lives, works, or might have been exposed
Down
- 1. the distortion of the association between an exposure and a health outcome by a third variable that is related to both
- 2. a measure of the impact of premature death on a population calculated as the sum of the differences between a predetermined minimally acceptable age and the age at death for everyone who died earlier than that age
- 5. the residue of dried droplets of infectious agents that is easily inhaled and exhaled and can remain suspended in air for relatively long period or be blown over great distances
- 6. a combination of symptoms characteristic of a disease or health condition;sometimes refers to a health condition without a clear cause
- 8. the ability of an infectious agent to cause severe disease, measured as the proportion of persons w/ the disease who become severely ill or die
- 10. an infectious disease that is transmissible from animals to humans
- 12. the ability of an infectious agent to cause infection, measured as the proportion of persons exposed to an infectious agent who become infected
- 13. a measure of the distribution of observations out from its central value. Measures of spread in epidemiology include the interquartile range, variance, and standard deviation
- 15. the study of the distribution and determinants of health conditions or events among populations and the application of that study to control health populations
- 16. the proportion of cases identified by a test, reported by a surveillance system or classified by a case definition that are true cases, calculated as the number of true-positives divided by the number of true-positives plus false-positives
- 18. a form of incidence that measures the proportion of persons in a population who experience an acute health event during a limited period, calculated as the number of new cases of a health problem during an outbreak divided by the size of the population at the beginning of the period, usually expressed as a percentage or per 1000 or 100000 population
- 19. a measure of association that quantifies the association between an exposure and a health outcome from epidemiologic study, calculated as the ratio of incidence proportions of two groups
- 21. the constant presence at high incidence and prevalence of an agent or health condition within a given geographic area or population
