This study used the 2014 Ebola outbreak as a case study to compare news coverage of a Public Health Emergency of International Concern (PHEIC) between the Polarized Pluralist media system and the Liberal media system. This investigation revealed that partisan frames, emphasis on local and international efforts and use of health expert sources all differed across the two media systems. These differences suggest that social, political and economic attributes of media systems affect how news is shaped. When an event of international significance occurs, such as a disease outbreak, the characteristics that make up a media system will influence how issues are covered and presented to the public. Giving the current globalized nature of news, the findings in this study has implications for international news flow.

死亡叙述：国际关注的突发公共卫生事件覆盖范围的系统决定因素

本研究以 2014 年埃博拉疫情为案例研究，比较两极分化的多元主义媒体系统和自由媒体系统对国际关注的突发公共卫生事件 (PHEIC) 的新闻报道。这项调查显示，两个媒体系统的党派框架、对本地和国际努力的强调以及对健康专家资源的使用都不同。这些差异表明，媒体系统的社会、政治和经济属性会影响新闻的形成方式。当发生具有国际意义的事件（例如疾病爆发）时，构成媒体系统的特征将影响对问题的报道和向公众呈现的方式。鉴于当前新闻的全球化性质，本研究的发现对国际新闻流动具有影响。
