Delivering risk information in a dynamic information environment: Framing and authoritative voice in Centers for Disease Control (CDC) and primetime broadcast news media communications during the 2014 Ebola outbreak

摘要

Objective: During a disease outbreak, media serve as primary transmitters of information from public health agencies to the public, and have been shown to influence both behavior and perception of risk. Differences in news frequency, framing and information source can impact the public's interpretation of risk messages and subsequent attitudes and behaviors about a particular threat. The media's framing of an outbreak is important, as it may affect both perception of risk and the ability to process important health information.
