CDC Epidemiology Case Studies

CDC developed case studies in applied epidemiology based on real-life epidemiologic investigations and used them for training new Epidemic Intelligence Service (EIS) officers — CDC’s “disease detectives.” EIS offers these carefully crafted epidemiology case studies for schools of medicine, nursing, and public health to use as a component of an applied epidemiology curriculum.

How are the case studies used?

Students may practice their epidemiologic skills by using these exercises in classroom activities or as homework assignments to reinforce principles and skills previously covered in lectures and reading assignments.

  • In-Class Activity: Students, read the case study up to the first question and then perform calculations, construct graphs, or discuss the answer. Students may be asked to play different roles in answering the question. After discussing the first answer satisfactorily, read on to the next question and continue with the exercise.
  • Individual Activity: Students, for a homework assignment, read the case study and answer the questions, then discuss the findings in class.

The following case studies use specific examples to teach epidemiology concepts, require active participation, and help strengthen problem-solving skills. These case studies in applied epidemiology:
