Risk can be defined using a mathematical formula—probability multiplied by consequences. An essential element of risk communication is a focus on messages within organizations. However, many health-related risks such as Ebola extend beyond an individual organization and risk is better understood as a social construction cogenerated within and between systems. Therefore, the process is influenced by systemic and supra-systemic values and predilections. Risk from a structurational perspective allows an understanding of the public as well as organizational responses to risk. Structuration theory provides a useful lens to move beyond seeing organizations as something that flows within an organization to understanding how organizations are enacted through communication. Structuration theory articulates the connections between systems and structures through the action of agents, whose practices produce and reproduce the rules and resources of social life. Within the structuration tradition, organizational communication scholars have shifted to an understanding of the communicative constitution of organizations (CCO). Specifically, one of the theories of CCO is the Four Flows Model. The four flows highlight the ways people enact organizations and provide a means to analyze the various ways communication constitutes organizations. The four flows are membership negotiation, activity coordination, reflexive self-structuring, and institutional positioning. Membership negotiation enacts the inner members and outsiders at a basic level including socialization, identity, and assimilation. Activity coordination produces collective action around a specific goal. Reflexive self-structuring is the decentralized enactment of structures for the organization through the communication of policies. Institutional positioning covers the macro-level actions where people in the organization act as an entity within the environment. When considering the public reaction to Ebola, a simple way to evaluate risk perception is the intersection of dread and control. The U.S. public considered Ebola a serious risk. From a structuration perspective, the viral nature of twitter, media coverage, and public discussion generated resources for fear to be exacerbated. Structuration theory allows us to position the risk beliefs as rules and resources that are reproduced through discourse. The organizational implications fall primarily into the two flows of institutional positioning and reflexive self-structuring. For institutional positioning, U.S. healthcare organizations faced general public dread and perceived lack of control. Within the United States multiple policies and procedures were changed, thus fulfilling the second flow of organizational self-structuring. The Ebola risk had a significant impact on the communicative constitution of health-care organizations in the United States and beyond. Overall, risk is communicatively constituted, as are organizations. The interplay between risk and health-care organizations is evident through the analysis of American cases of Ebola. Structuration theory provides a means for exploring and understanding the communicative nature of risk and situates that risk within the larger systems of organizations.
