背景：目前2019年新型冠状病毒疫情正在迅速发展。YouTube已被公认为以前疾病爆发的流行信息来源。我们分析了YouTube上关于n-CoV的英语和普通话内容。方法：2020年2月1日和2日，使用“2019新型冠状病毒”，“武汉病毒”和（武汉病毒的普通话）检索YouTube。每组中的前50个视频被分析。排除其他语言的视频、重复视频、没有音频且持续时间> 15 min的视频。审查了72个英语视频和42个普通话视频。2名评审员根据预先规定的标准将视频分类为有用，误导或新闻。观察者间一致性采用kappa系数进行评价。结果：共获得21，288，856次浏览量。67%的英语视频和50%的普通话视频提供了有用的信息。误导性普通话视频的收视率高于有用的视频。世卫组织仅占有用视频的4%。英文和普通话视频的DISCERN平均信度评分分别为3.12/5和3.25/5。有用视频的平均累积MICI评分较低（英语为6.71/25，普通话为6.28/25）。结论：2019年n-CoV爆发期间的YouTube观看人数高于以往的爆发。视频的医疗内容不够理想，国际卫生机构的代表性不足。鉴于其受欢迎程度，YouTube应被视为信息传播的重要平台。
Background: The current 2019 novel coronavirus outbreak is rapidly evolving. YouTube has been recognized as a popular source of information in previous disease outbreaks. We analyzed the content on YouTube about n-CoV in English and Mandarin languages.Methods: YouTube was searched using the terms '2019 novel coronavirus', 'Wuhan virus' and (Mandarin for Wuhan virus) on 1st and 2nd February 2020. First 50 videos in each group were analyzed. Videos in other languages, duplicate videos, those without an audio and duration > 15 min were excluded .72 videos in English and 42 in Mandarin were reviewed. 2 reviewers classified the videos as useful, misleading or news based on pre specified criterion. Inter-observer agreement was evaluated with kappa coefficient. Modified DISCERN index for reliability and medical information and content index (MICI) score were used for content analysis.Results: These videos attracted cumulative 21,288,856 views. 67% of English and 50% Mandarin videos had useful information. The viewership of misleading Mandarin videos was higher than the useful ones. WHO accounted for only 4% of useful videos. Mean DISCERN score for reliability was 3.12/5 and 3.25/5 for English and Mandarin videos respectively. Mean cumulative MICI score of useful videos was low (6.71/25 for English and 6.28/25 for Mandarin).Conclusions: YouTube viewership during 2019 n-CoV outbreak is higher than previous outbreaks. The medical content of videos is suboptimal International health agencies are underrepresented. Given its popularity, YouTube should be considered as important platform for information dissemination.
