Introduction to Epidemiology

Project Summary: For your session-long project, you will investigate an outbreak.

You work in the community outreach department at the Disease Control Office at the Wintersburg County Health Department. You have been requested to attend an emergency meeting with some epidemiologists. During the meeting, you were informed that 40 kids became ill with diarrhea and fever at Wintersburg Elementary School. Ten children were hospitalized. The diagnosis is Salmonella infection.

Assignment:

According to the epidemiologic triangle, there are three factors that influence the occurrence of disease:

Host factors
Environmental factors
Describe each of these factors for food-borne Salmonella infection. Do they all need to be present for disease to occur? (Review "Multiple Causation of Disease" on the modular Homepage.)
