Study: COVID-19 warnings were on Twitter well before outbreak of pandemic

Study: COVID-19 warnings were on Twitter well before outbreak of pandemic ANI | Updated: Jan 25, 2021 21:13 IST Lucca [Italy], January 25 (ANI): A new study shows that posts revealing concern for pneumonia circulated very early, suggesting social media can be an effective tool for epidemiological surveillance. Even before public announcements of the first cases of COVID-19 in Europe were made, at the end of January 2020, signals that something strange was happening were already circulating on social media. The new study led by researchers at IMT School for Advanced Studies Lucca was published in Scientific Reports. It has identified tracks of increasing concern about pneumonia cases on posts published on Twitter in seven countries, between the end of 2019 and the beginning of 2020. The analysis of the posts shows that the whistleblowing came precisely from the geographical regions where the primary outbreaks later developed.
