During an emerging infectious disease outbreak, television news becomes an important channel for communicating threat and efficacy information. In this study, we conduct a content analysis to assess the degree to which television news contained threat and efficacy information during the 2016 Zika virus outbreak. The results show significantly more threat information than efficacy information in broadcast news reports. Individual efficacy and collective efficacy information were communicated at approximately the same rate. These findings indicate a continued need for public health communicators to emphasize collective and individual efficacy information when communicating with the media.

电视新闻中的威胁和功效：关于一种新兴传染病的报道

在新兴的传染病暴发期间，电视新闻成为传达威胁和功效信息的重要渠道。在这项研究中，我们进行了内容分析，以评估2016年寨卡病毒爆发期间电视新闻包含威胁和功效信息的程度。结果显示，广播新闻报道中的威胁信息比功效信息多得多。个人功效和集体功效信息以大约相同的速度传达。这些发现表明，在与媒体进行交流时，公共卫生传播者仍然需要强调集体和个人的功效信息。
