Epidemiologic field investigations usually are initiated in response to epidemics or the occurrence of other acute disease, injury, or environmental health problems. Assessing causality at each step in an investigation is important not only for assessing the strength of evidence developed up to that point, but also in helping to identify what evidence is missing or requires further attention and for planning additional approaches (e.g., data gathering and analysis) essential for supporting decisions regarding interventions.

In this chapter, the model used to systematically identify and characterize the spectrum of intervention options for outbreaks and other acute health threats focuses on two basic biologic and environmental dimensions: (1) interventions that can be directed at the source(s) of most infectious and other disease-causing agents and (2) interventions that can be directed at persons susceptible to such agents (Box 11.2).
