Course Project Part 5 – BIO 250L


As you, the public health epidemiologist, studied the EATC virtual line list, created in the last unit, of ill residents, you discovered an interesting pattern in the person, place and time associations with illness. See Table 1 (below) for a summary of your observation in terms of place. No cases were found in cottage clusters 4 and 6.

This simple data analysis caused you to become more curious about the cause of the Gastrointestinal (GI) illness.

Answer the questions below. Write your answers in complete sentences. You may need to use additional resources outside of your textbook to complete this part of your project. Please be sure to cite any sources you may use with APA and include a Reference page.


  1. Create a graph comparing the number of ill residents in each cottage cluster.
  • What is the attack rate for GI illness among all EATC residents?
  • What is Clostridium perfringens enterotoxin (CPE)? How is it transmitted to humans? What symptoms can it cause?
