论文摘要
我们分析了Twitter的数据,以发现2019 - 2020年冬季在欧洲爆发的欧洲爆发的早期预告信号,然后在首次公开宣布当地感染源。我们证明了证据表明,在许多欧洲国家,人们提出了对肺炎病例的意外关注。举报主要来自地理区域,这些地区最终被证明是感染的关键繁殖场。这些发现表明,建立综合数字监视系统的紧迫性,在该系统中,社交媒体可以帮助地理定位的传染链,否则几乎完全未被发现。
We analyze data from Twitter to uncover early-warning signals of COVID-19 outbreaks in Europe in the winter season 2019-2020, before the first public announcements of local sources of infection were made. We show evidence that unexpected levels of concerns about cases of pneumonia were raised across a number of European countries. Whistleblowing came primarily from the geographical regions that eventually turned out to be the key breeding grounds for infections. These findings point to the urgency of setting up an integrated digital surveillance system in which social media can help geo-localize chains of contagion that would otherwise proliferate almost completely undetected.
