Directions:

This assignment is to be done alone with you as the sole author. Any work that appears to have been done in groups or with a partner will receive a zero.

Questions:

Part I: Disease Outbreak

The following exercise was adapted from:

Huang, FI, and Bayona, M. “Disease Outbreak Investigation” – The Young Epidemiology Scholars Program. Supported by the Robert Wood Johnson Foundation and administered by the College Board.

One hundred and fifty people attended a charity luncheon in which two different menus were served. A total of 82 attendees reported symptoms including nausea, vomiting, abdominal cramps and diarrhea.

Most of the 82 patients who became sick reported symptoms about six hours after the beginning of the luncheon. The symptoms lasted from four to seven hours. The dishes that were served included baked chicken, meat loaf, mashed potatoes and green beans. The table below shows the data collected from this investigation.

(HAPP 420)

(1)

A.) (8 points) Calculate the total number of people who ate and did not eat each food item. B.) (2 points) What is the formula for the attack rate?

C.) (8 points) Calculate in the table above the attack rates per 100 for those who ate each food item.

D.) (8 Points) Calculate in the table above the attack rates per 100 for those who did not eat each food item.

PART II: AGENT CHARACTERISTICS

Disease X is one that often results in severe illness but is never fatal. On March 21, 2002, 80 students enrolled in an introductory epidemiology course at a university developed disease X. Assume all epidemiology students were exposed to the index case, the instructor.

Through antibody titers we were able to determine the following (antibody titers measure the concentration of antibodies in individuals and can be used to provide evidence of infection):

# Of exposed students not infected 40

# Of exposed students with subclinical infection 10

(HAPP 420)

(2)

# Of exposed students with mild symptoms 10

# Of exposed students with moderate symptoms 10

# Of exposed students with severe symptoms 10

(4 points) Define “infectivity.”
(4 points) What is the infectivity of disease X?

HINT: Infectivity can be measured by the attack rate=(# infected / # susceptible) X 100

(4 points) Define “pathogenicity.”
(4 points) What is the infectivity pathogenicity of disease X?

HINT: Pathogenicity= (# with clinical disease / # susceptible) X 100

(4 points) Define “virulence.”
(4 points) What is virulence of disease X?

HINT: virulence = (# with clinical symptoms/ # with disease) X 100

RUBRIC

Excellent Quality

95-100%

Introduction

45-41 points

The context and relevance of the issue, as well as a clear description of the study aim, are presented. The history of searches is discussed.

Literature Support

91-84 points

The context and relevance of the issue, as well as a clear description of the study aim, are presented. The history of searches is discussed.

Methodology

58-53 points

With titles for each slide as well as bulleted sections to group relevant information as required, the content is well-organized. Excellent use of typeface, color, images, effects, and so on to improve readability and presenting content. The minimum length criterion of 10 slides/pages is reached.

Average Score

50-85%

40-38 points

More depth/information is required for the context and importance, otherwise the study detail will be unclear. There is no search history information supplied.

83-76 points

There is a review of important theoretical literature, however there is limited integration of research into problem-related ideas. The review is just partly focused and arranged. There is research that both supports and opposes. A summary of the material given is provided. The conclusion may or may not include a biblical integration.

52-49 points

The content is somewhat ordered, but there is no discernible organization. The use of typeface, color, graphics, effects, and so on may sometimes distract from the presenting substance. It is possible that the length criteria will not be reached.

Poor Quality

0-45%

37-1 points

The context and/or importance are lacking. There is no search history information supplied.

75-1 points

There has been an examination of relevant theoretical literature, but still no research concerning problem-related concepts has been synthesized. The review is just somewhat focused and organized. The provided overview of content does not include any supporting or opposing research. The conclusion has no scriptural references.

48-1 points

There is no logical or apparent organizational structure. There is no discernible logical sequence. The use of typeface, color, graphics, effects, and so on often detracts from the presenting substance. It is possible that the length criteria will not be reached.
