Annotation

The course will introduce key concepts in epidemiology that are needed for public health practice. These concepts include the measures of disease frequency, principles and techniques of surveillance, outbreak investigation, measures of association used in epidemiologic studies, causal reasoning, confounding, bias, and epidemiologic study design.

Learning Objectives

• To discuss different methods of depicting data.

• To discuss the elements of a valid statistical association.

• To examine some descriptive data and discuss interpretations.

• To discuss the term “cohort effect”.
