Previous studies had examined what world leaders tweeted about COVID-19, or racist content in COVID-19 tweets, or social media posts from one particular country or region. This is perhaps the first study to examine COVID-19-related tweets posted worldwide to uncover public opinions, sentiments and trends over a period of time, according to the authors.
Ranganathan Chandrasekaran, professor of information and decision sciences in the UIC College of Business Administration, said his team did so by analyzing expressions of concerns, opinions and feelings about the pandemic posted in more than 13.9 million English-language COVID-19-related tweets.
The researchers found that 20.51% of tweets were about
COVID-19’s impact on the economy and markets, followed by spread and growth in cases (15.45%), treatment and recovery
(13.14%), impact on the health care sector (11.40%), and governments’ response (11.19%).
Sentiment analysis, scores were found to be negative throughout the examined time period for the topics of spread and growth of cases, symptoms, racism, source of the outbreak, and the political impact of COVID-19.
However, the researchers noticed a reversal of sentiments in March from negative to positive for prevention, impact on the economy and markets, governments’ response, impact on the health care industry, and treatment and recovery.
“Individuals worldwide have now become optimistic about economic recovery and have adjusted to the ‘new normal’ way of living,” Chandrasekaran said. “Activities like social distancing and personal hygiene did not find favor among the public in the initial weeks of the pandemic, but found support only later.”
Chandrasekaran added that public sentiment pointed to the need for better emergency preparedness in health institutions and hospitals, such as having clear policies for dealing with ventilators and handling high-risk patients.
The study, titled “Topics, Trends, and Sentiments of Tweets About the COVID-19 Pandemic: Temporal Infoveillance Study,” was co-authored by UIC graduate students Vikalp Mehta and Tejali Valkunde, and Evangelos Moustakas, Middle- sex University, Dubai, United Arab Emirates.
