Cause and Effect in Epidemiology

Ripples in water.Determining the cause of a disease or the positive effect of a health activity is an important part of decision-making in public health. But how do we know if something actually does cause a disease or improve our health? Inferring causality is a step-by-step process requiring a variety of information. In this module, Dr. Victoria Holt discusses seven guidelines to use in determining whether a specific agent or activity causes a health outcome. She illustrates each guideline with a public health example.
