The ongoing H1N1 influenza pandemic has created a significant amount of health concern. Adequate dissemination of correct information about H1N1 influenza could help in decreasing the disease spread and associated anxiety in the population.
This study aims to examine the effective use of the popular Internet video site YouTube as an information source during the initial phase of the H1N1 outbreak.
YouTube was searched on June 26, 2009, using the keywords swine flu, H1N1 influenza, and influenza for videos uploaded in the past 3 months containing relevant information about the disease. The videos were classified as useful, misleading, or as news updates based on the kind of information contained. Total viewership, number of days since upload, total duration of videos, and source of upload were noted.
A total of 142 videos had relevant information about H1N1 influenza. In all, 61.3% of videos had useful information about the disease, whereas 23% were misleading. Total viewership share of useful videos was 70.5%, whereas that of misleading videos was 17.5%, with no significant difference in viewership/day. The CDC contributed about 12% of the useful videos, with a significant viewership share of 47%. No significant differences were seen in viewership/day for useful videos based on the kind of information they contained.
YouTube has a substantial amount of useful information about H1N1 influenza. A source-based preference is seen among the viewers, and CDC-uploaded videos are being used in an increasing proportion as a source of authentic information about the disease.
当前的 H1N1 流感大流行引起了公众对健康的极大关注。充分传播关于 H1N1 流感的正确信息有助于减少疾病传播和公众的焦虑。
本研究旨在考察在 H1N1 爆发初期，流行的互联网视频网站 YouTube 作为信息来源的有效性。
于 2009 年 6 月 26 日，使用“猪流感”、“H1N1 流感”和“流感”等关键词在 YouTube 上搜索过去 3 个月内上传的包含有关疾病信息的视频。根据视频中包含的信息内容，将视频分为有用、误导或新闻更新。记录总观看次数、上传后天数、视频总时长和上传来源。
共有 142 个视频包含有关 H1N1 流感的相关信息。所有视频中，61.3%的视频提供了有用的疾病信息，23%的视频具有误导性。有用视频的总观看份额为 70.5%，而误导性视频的观看份额为 17.5%，两者的日观看量没有显著差异。美国疾病预防控制中心（CDC）贡献了约 12%的有用视频，其观看份额为 47%。根据视频内容的不同，有用视频的日观看量没有显著差异。
YouTube 上有大量关于 H1N1 流感的有用信息。观众对来源有偏好，并且随着时间的推移，CDC 上传的视频作为疾病真实信息的来源比例在不断增加。
