Effective community mitigation through voluntary behavior change is currently the best way to reduce mortality caused by coronavirus disease (COVID-19). This study builds on our prior study based on the scientific premise that YouTube is one of the most effective ways to communicate and mobilize the public in community mitigation to reduce exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
Because of the rapidly changing nature of YouTube in the context of the COVID-19 pandemic, we conducted a follow-up study to document how coverage of preventive behaviors for effective community mitigation has changed.
A successive sampling design was used to compare coverage of behaviors to mitigate community transmission of COVID-19 in the 100 most widely viewed YouTube videos in January 2020 and March 2020.
Videos in the January and March samples were viewed >125 million times and >355 million times, respectively. Fewer than half of the videos in either sample covered any of the prevention behaviors recommended by the US Centers for Disease Control and Prevention, but many covered key prevention behaviors and were very widely viewed. There were no videos uploaded by entertainment television in the January sample, but this source comprised the majority of videos and garnered the majority of cumulative views in the March sample.
This study demonstrates the incredible reach of YouTube and the potential value of partnership with the entertainment industry for communicating and mobilizing the public about community mitigation to reduce mortality from the COVID-19 viral pandemic.
通过自愿行为改变进行有效的社区缓解是目前降低冠状病毒病(COVID-19)死亡率的最佳方法。本研究基于我们之前的研究,该研究基于科学前提,即 YouTube 是在社区缓解中进行沟通和动员公众以减少接触严重急性呼吸系统综合症冠状病毒 2(SARS-CoV-2)的最有效方法之一。
由于 COVID-19 大流行背景下 YouTube 的性质迅速变化,我们进行了一项后续研究,以记录有效社区缓解预防行为的覆盖范围如何发生变化。
采用连续抽样设计,比较 2020 年 1 月和 2020 年 3 月 100 个最受欢迎的 YouTube 视频中对减轻 COVID-19 社区传播行为的报道。
两个样本中的视频观看次数均超过 1.25 亿次和 3.55 亿次。两个样本中不到一半的视频涵盖了美国疾病控制与预防中心推荐的任何预防行为,但许多视频涵盖了关键的预防行为,并且观看量非常大。在 1 月的样本中没有上传任何娱乐电视视频,但这一来源在 3 月的样本中占了大多数视频,并获得了大部分累计观看次数。
本研究证明了 YouTube 的巨大影响力,以及与娱乐行业合作传播和动员公众进行社区缓解以降低 COVID-19 病毒性大流行死亡率的潜在价值。
