Infectious disease, public health, and politics: United States response to Ebola and Zika.

Politics, rather than disease characteristics, complicated the United States response to Ebola virus disease and Zika virus. We analyze how media and political elites shaped public opinion of the two outbreaks. We conducted a retrospective analysis of media coverage, Congressional floor speech, and public opinion polls to explain elite cueing and public perceptions of Ebola and Zika. We find evidence of elite cueing by Congress and the media on public opinion. Public opinion of both disease outbreaks initially followed partisan patterns. However, while Ebola public opinion remained partisan, ultimately, opinion emerged of a bipartisan nature for Zika, mirroring elite framing. Public health officials should be aware of how elite cueing shapes policy and prioritizes partisan strategies. Politics and public opinion can focus attention on or away from infectious disease; it can also undermine public health responses by biasing the public's view of a diseases' relative risk.
