GCH 412
Team Epidemiology Report
Purpose: As a team, examine a communicable disease issue and apply the epidemiologic skills developed in this class to analyze, describe, and present the situation and conclusion of the study.
Group Size: Four members on each team. Team members need to be submitted by February 18th on Blackboard.
Case Studies: Each group will be assigned one of five case studies. The team assignments and case studies will be posted on Blackboard after team submissions have been completed.
Report Summary: This project will consist of 25% of your final grade. The two sections of this project will be averaged together to create the final grade of the project. The two sections of this report will be:
- Written Abstract: Each team will submit an abstract (hard copy by email) with no greater than 600 words describing their study. Each abstract is required to be comprised of these sections:
- Background-Study objectives, hypothesis, or a description of the program.
- Methods-Study design and appropriate statistical analysis.
- Results-Specific results in summary form.
- Conclusions-Description of the main outcome of the study.
Make sure that your team goes online to read drafts of epidemiology abstracts to see what these reports look like.
- Group Presentation: Each team will also give a 10 minute presentation to the class on their topic. The presentation will be constructed around the sections of the abstract. Each team member is responsible for presenting one section. Students not presenting are responsible for providing constructive commentary on the presentations they are watching. Failure to provide this commentary will result in a 10 point deduction in the presentation grade for every day of presentations missed (1 day missed = 10 point deduction, 2 days missed = 20 point deduction). I will provide commentary forms for you to complete in class. Presentation and audience times will also be provided on Blackboard.
Case Study #4- Wedding Nightmare
July 5th 10AM: The Fairfax County Health Department receives a call from a local resident who went a wedding the previous weekend. He states that “according to Facebook, everyone is sick who attended the wedding.”
July 5th 11AM: FCHD begins their investigation. They interview the complainant and get the contact information for the bride and groom. FCHD then leaves a message for the bride and groom to get more information about the wedding.
July 5th 1:00PM: The bride and groom return the call. They confirm that they heard about numerous individuals who were sick with vomiting and diarrhea after their wedding. They don’t know the exact number but confirm that the wedding had 75 guests and a small reception was held on a boat on June 29, 2013 after the wedding. The only food served during the wedding was a few appetizers catered by the boat company. The boat also had an open bar for the two hour reception. The bride and groom give the Health Department permission to send a survey to all of the guests asking about symptoms and food history from the guest list they provided. Environmental Health is sent out to inspect the boat food processes and receive a copy of the food served.
July 5th 4PM: EH completes their inspection and sends the menu to the epidemiologist. EH notes that although no food service workers reported illness before or during the event, the bartender had been sick with vomiting and diarrhea the morning before he worked. The epidemiologist at the Health Department completes the survey that asks about medical history and food items consumed. The survey is put on Survey Monkey and is sent to all of the employees at the office.
July 6th 9AM: The survey is emailed to all the guests of the wedding.
July 8th 11AM: The survey is closed by the epidemiologist. There are 42 responses to the survey (Data next page). The survey results also request that three individuals are willing to submit stool specimens to be tested. The Health Department collects the specimens and sends to the state lab for testing.
July 9th 4PM: All three specimens are confirmed norovirus by the state lab by PCR testing
June 11th: The epidemiologist analyzes data, writes abstract, and presents to their health director.
