Then select the Check Answers button to submit your answer. Efforts to prevent fecal-oral transmission often focus on rearranging the environment to reduce the risk of contamination in the future and on changing behaviors, such as promoting hand washing. Palmer SR. J Infect Dis 1992;165:736–9. This graph, called an epidemic curve, or epi curve for short, provides a simple visual display of the outbreak’s magnitude and time trend. Using the information about disease and exposure status, the investigator then calculates an odds ratio to quantify the relationship between exposure and disease. Last JM. Use this diary. In other words, epidemiologists cannot afford to conduct an investigation that is “quick and dirty.” They must conduct investigations that are “quick and clean.”(22) Under such circumstances, epidemiologists find it useful to have a systematic approach to follow, such as the sequence listed in Table 6.2.

For the area identified, choose the label component that best describes the part indicated. What is the chemical route of entry? Here is the crucible of an unprecedented form of power marked by extreme concentrations of knowledge and free from democratic oversight. The first step in interpreting an epidemic curve is to consider its overall shape. Usually, the first effort to identify cases is directed at healthcare practitioners and facilities — physicians’ clinics, hospitals, and laboratories — where a diagnosis is likely to be made. In other words, epidemiologists can use analytic epidemiology with its hallmark comparison group to quantify relationships between exposures and disease, and to test hypotheses about causal relationships. An example of the line listing from the 2001 anthrax investigation is shown in Table 6.5. Public Health Reports 2003; 118:92–8. If the disease and its incubation period are known, the epi curve can be used to deduce a probable time of exposure and help develop a questionnaire focused on that time period.
