Please join the Discussion each week. Replies must be posted in the week due and replies after the end of the each week will not be graded or receive credit. The discussions are for student interaction and input and must be submitted before the week ends in order to receive full credit. Students should demonstrate their own knowledge in the discussions and avoid copying and pasting from websites. The Rubric is attached to discussion description.
- Post your initial response to each discussion by 11:55pm, ET, Wednesday.
- Initial responses should have substance where students explore, explain, and expand upon issues being discussed, and apply relevant course materials.
- Students should analyze course concepts, theories or materials correctly, using examples or supporting evidence.
- Initial responses should be supported by at least two references (APA referencing format is not required for discussions)
- For each discussion, reply to at least 2 of your classmates by 11:55pm, ET, Sunday.
- Students are required to respond to at least two (2) other student’s initial postings (and the instructor) with significant comments that have substance.
- Students should collaborate with fellow learners, relating the discussion to course concepts, add several innovative ideas, and provide considerable additional insight that relates to core concepts.
- Peer responses should include at least two (2) of the following components: Offering advice; posing a question; providing an alternative point-of-view; and acknowledging similar experiences.
- Peer responses should be supported by at least one reference (APA referencing format is not required for discussions)
- All discussions can be accessed in the discussion section of the course.
- A Discussion rubric is included in the discussion section of the course
- More in-depth specific instructions for each discussion can be found in the discussion tab within the course.
- Late Discussion posts receive a 10% per day late penalty. If your 2 peer responses are posted after the week is ended (after Day 7, Sunday) they receive a zero, and that the discussion is finished. You cannot receive credit for participation in a discussion with others after the discussion week has closed.
- If there are less than 3 students in the course, only one (1) peer posting will be required. Your peer postings should challenge or expound upon at least one of the points made by your peer, and “I agree” does not constitute as an adequate response. As graduate students, you will be expected to provide comprehensive, relevant and well supported points in your assignments.
We all bring something unique to the classroom, from our understanding, our experiences, and our value systems. We honor and respect each person’s diverse beliefs to help us see beyond the classroom to be the most effective individuals we can be. Therefore, we should all be respectful of others while expressing our viewpoints and opinions. Proper Netiquette behavior is expected. Any inflammatory, demeaning or disrespectful language in a posting will be immediately removed from the discussion space.
Week 7: Outbreak Investigation. For this assignment, you will need to use Microsoft Excel or OpenOffice Spreadsheets. All students have access to Microsoft 365 through APUS. Please contact Tech Support for help in accessing Microsoft Excel. You will conduct an outbreak investigation using the information given to you in the assignment. You will need to make calculations in Excel and make a graph to include in your final report.
On February 7, 2018, a nurse employed at the Flinn Corporation noticed an increase in the number of employees who were sick. She was concerned that there may be a Salmonella outbreak at the company. She has interviewed each of the employees at the corporation. She has taken samples and sent them out for testing but has not received the results. She asks you, the local epidemiologist, to investigate to see if an outbreak exists and if so what the source of the outbreak is. You follow the Center for Disease Control and Prevention's steps in outbreak investigation (https://www.cdc.gov/csels/dsepd/ss1978/lesson6/section1.html) and report your findings to her. Please note that we will not address all outbreak investigation steps in this assignment.
Use the attached Excel worksheet to produce graphs and statistics to answer the questions below. Submit your report as a Word doc (or PDF) and include figures and tables you generate. The report should be easy to follow and interpret and should be written as an academic paper in proper APA formatting.
1. Look at the Excel Spreadsheet attached. There are 3 worksheets (see tabs on bottom of page - "Nurse's Interview", "Epi Curve", "Retrospective Cohort Study"). The first sheet "Nurse's Interview" has a line list of employees who work at Flinn Corporation. This sheet represents the data the nurse has collected from those employees in an interview. Do you think that an outbreak exists? Why would you recommend to further investigate? Discuss your reasoning. (Step 2: Establish outbreak)
2. Research salmonellosis using academic sources. Are the symptoms that the ill employees exhibit consistent with salmonellosis? Provide a brief summary (1-2 paragraphs) of the disease and discuss the chain of infection for this disease. Use in-text citations in proper APA format and include all sources in your reference section. (Step 3: Verify diagnosis)
3. Identify the percentage of ill employees with each symptom. For example, 1 out of 12 ill employees had blood in stool (Bs) = 8.3%. (Step 4: Working case definition)
4. Conduct descriptive epidemiology (Step 6). Describe the characteristics of the ill employees to determine trends and risk factors.
a. Person - Calculate the percentage of ill employees that are male/female. Determine the mean age of the ill employees.
b. Place - What percentage of ill employees ate at the cafeteria? What percentage of well employees ate at the cafeteria?
c. Time - Using the data collected in the Nurse's Interview, fill in the column "# of cases" in the "Epi Curve" worksheet. Use 0 if there are no cases. As you fill in the data, the graph will automatically generate. Choose an appropriate title for the graph. Copy and paste graph into your report. What type of epidemic curve is it ? (Hint: read https://www.cdc.gov/csels/dsepd/ss1978/lesson6/section2.html#step6)
5. Based on the information you have gathered, you have developed an hypothesis that there is a food being served at the cafeteria that is causing the employees to become ill. You need to further test this hypothesis by conducting a retrospective cohort study (Step 8). Use the worksheet "Retrospective Cohort Study" to calculate attack rates and risk ratios. The first food item Baked Chicken is done for you. You can also consult https://www.cdc.gov/csels/dsepd/ss1978/lesson6/section2.html#step8 for help. Report the Risk ratio for each food item. Based on risk ratios, which is food is most likely to be the source of the illness? Explain.
6. Based on your findings, what would you recommend for prevention and control measures? Apply food safety principles from academic sources to discuss further prevention of Salmonella outbreaks in the cafeteria. (Step 11) Use in-text citations and include sources in reference section.
7. Include a properly formatted reference section in APA format that includes at least 3 academic sources (popular sources should not be used).
- More in-depth specific instructions for each assignment can be found in the Assignment tab within the course.
- Assignments submitted late without advance notice will receive a 5% per day late penalty and will not be accepted for grading five (5) days past the due date.
