Discuss the importance of validity and reliability.
Evaluate the steps for investigating the occurrence of disease.

Oswego Outbreak Case Study

Read the “Oswego Outbreak Investigation,” located in the Topic Materials.

Part 1

Complete the following:

Using the line listing in the Excel “Oswego Line Listing Workbook,” calculate the attack rate ratios for each food item using the table in the Excel “Oswego Attack Rate Table.” Create a separate 2×2 table for the food item you think is responsible for the outbreak and interpret the attack rate ratio for this food item. Refer to the “Creating a 2×2 Contingency Table” resource for guidance. pub 540 Principles of epidemiology Topic 2: Disease Surveillance and Measurement.
Using the line listing in Excel “Oswego Line Listing Workbook,” construct an epidemic curve by the time of onset of illness. What does this curve tell you regarding the average incubation period, source, and transmission?
Using the incubation range and clinical symptoms, identify potential infectious agents that could be responsible for the outbreak (refer to the Topic Material, “Compendium of Acute Foodborne and Waterborne Diseases”). Discuss your rationale. pub 540 Principles of epidemiology Topic 2: Disease Surveillance and Measurement.

Part 2

In a 500-750 word paper, evaluate the situation and present your findings. Including the following:

Does this case meet the definition of an “outbreak?” Why or why not?
Identify the steps required to investigate an outbreak. How did these steps help in investigating the Oswego event? Include the relevant information needed for each step to be successful.
Discuss the possible routes of transmission for the expected agent.
Based on this information, what control measures would you recommend? State whether they are primary, secondary, or tertiary prevention strategies. pub 540 Principles of epidemiology Topic 2: Disease Surveillance and Measurement.

Topic 2 DQ 1

Disease surveillance is a necessary public health role. Passive surveillance relies on individuals and local authorities “pushing” information to national agencies who then compile, analyze, and disseminate the information. Unfortunately, significant gaps occur in reporting.

Review your textbook, and the CDC’s National Notifiable Disease Surveillance System (NNDSS). Discuss the strengths of the current surveillance systems, the gaps you identified, and why these gaps occur. Discuss the global challenges of coordinating surveillance between multiple countries and provide an example highlighting the challenges. What could other governments and agencies, such as the World Health Organization and the Centers for Disease Control and Prevention, do to strengthen global disease surveillance systems? pub 540 Principles of epidemiology Topic 2: Disease Surveillance and Measurement
