During the Ebola virus disease epidemic in 20142015, public health officials in the United States used a combination of intervention measures directed at persons in whom Ebola virus disease was diagnosed (isolation), at their close contacts (active monitoring, quarantine, or restrictions on travel), at those providing healthcare to them (training in correct use of special protective gear and active monitoring), and at those arriving from selected countries (screening or active monitoring) (20). On February 26, 2020, the Advisory Committee on Immunization Practices (ACIP)recommended pre-exposure prophylaxis vaccination with rVSV-ZEBOV for adults 18 years of age in the U.S. population who are at potential occupational risk of exposure to Zaire ebolavirus. The severity of a specific problem is a principal determinant of the urgency and course of a field investigation and of any early intervention.

The social determinants of health framework also provides a guide to prevention, which requires changing both . Phase 2 placebo-controlled trial of two vaccines to prevent Ebola in Liberia. In his seminal article on criteria for assessing causal associations in epidemiology, Austin Bradford Hill concluded with a call for basing action on weighing the strength of the epidemiologic evidence against the severity of the consequences of delaying action and of taking premature action (1).

Field epidemiologists must consider multiple crucial determinants during the course of making a decision about whether a scientifically rational basis exists for employing an intervention and when selecting one or more specific interventions optimally matched to the public health problem. Primary prevention aims to prevent disease or injury before it occurs. In the interim, epidemiologists issued recommendations preventing further exposures and cases. Crime prevention can be described in terms of three stages or levels - primary, secondary and tertiary prevention.

When the problem is identified initially, the levels of certainty about the etiology, source, and mode of spread can range from known to unknown (Figure 11.1). Health Education can be applied at all three levels of disease prevention and can be of great help in maximizing the gains from preventive behavior. Nonetheless, field investigators should try to collect data for examining causality by using as many criteria as is feasible.

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). Ebola (Ebola virus disease): prevention and vaccine. Among certain sectorsfor example, the legal profession, private enterprise, and even regulatory agenciesacceptance of epidemiologic conclusions has been slower, in part because of the nature of causation in epidemiology: epidemiologic evidence establishes associations, not hard, irrefutable proof.
