Document Summary
Analytical epidemiology = involves examining health related data to determine the association between risk factors and the occurrence of health phenomenon. Biostatistics = re ects the analysis of data related to human organisms. Causality = determining whether a cause and effect relationship exists between a risk factor and a health effect. Demography = population level of study of person related variables or factors. Descriptive epidemiology = analysis of population and health data that are already available. Environment = all of the external factors that can in uence the host;s vulnerability to the risk factors related to the disease. Host = susceptible animal or human for an agent.
