Issue press releases, health alerts, and other information about risk reduction. 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).

Although this sort of prompt and appropriate response addresses the possibility of continued transmission on the basis of known agent-specific facts and experience, epidemiologists sometimes need to extend the investigation, depending on the circumstances and needs (e.g., when a trace-back is indicated to identify a continuing primary source for a restaurant-associated outbreak, such as shellfish or lettuce that was contaminated before being harvested) (5).
