Epidemiological information: E. coli O157:H7 illness in the Maritimes and Ontario
18 January 2013
What is epidemiology?
Epidemiology is the study of disease in a population. Epidemiologists, or disease detectives, use surveillance systems to identify those who are sick and confirm that the sick people are part of this event. They then gather information from the people who got sick and review the clues from all parts of the investigation that might reveal the cause of the illness event.
The figure and table below form part of the epidemiological investigation into this outbreak. An "epi curve" (Figure 1) is a valuable reference tool in any epidemiological investigation. An epi curve shows when cases begin, when they peak, and when they trail off. Certain details of the people who got sick (Table 1) also help epidemiologists as they work to solve the questions involved in foodborne illness.
