Assignment Expectations That you will present your methods of investigation and study using standard epidemiologic designs appropriate for this outbreak. Assignments should be of sufficient length appropriate for the case assignment. Additional expectations for the assignment: 1. Your references and citations should be consistent with a particular formatting style, such as APA. 2. Your response should be based on scholarly material, such as peer-reviewed articles, white papers, interval calculators above useful. Case?

Distance between residence and airport (mi) Travel History to Kinshasa, Zaire (6-10 weeks ago) Persons 29 Yes Yes 0-10 5 No Yes 0-10 Yes X] Yes ch Chp Assignment The World Health Organization recently announced that the virus causing HBPS (Hemorrhagic Black Pox Syndrome) in Athens, Greece is a new pathogen that has never been seen before in humans. Within 24 hours after arriving in Athens, you developed a standardized questionnaire to determine the likely source of the outbreak. Within a couple of days, you interviewed 45 cases and 35 controls about their clinical symptoms and exposures. During your interviews, you have discovered that a number of individuals just returned home about six weeks ago from a 1-month military mission abroad in Kinshasa, Zaire. Based on preliminary analysis of your data, it appears that either travel history to Zaire and/or residing near the airport may be associated with HBPS. What type of study design are you using to investigate the source of transmission? Explain. What surveillance methods would you use to find additional cases? What is your hypothesis? How would you select controls for this investigation? Would you use matching? Why or why not? Analyze the exposure data below by calculating the appropriate measure of association and 95% confidence intervals for each exposure among the cases and unmatched controls. Use stratification to separate the confounding effects of the other exposure. Show your work in the calculating the measures of association.

Part 4.
How would you select controls for this investigation? Would you use matching? Why or why
not?
Answer.
Basically the controls refers to the groups which are used in the investigation. Selecting the
controls or the groups I would use the following principles, the comparison group that is the
controls should be representative of the source populations which is has attributed to the
production of the stated cases. Then the groups or the controls must be sampled in a manner
which is not dependent to the exposure. And this means that the selection should not lead to...
