The COVID-19 pandemic is still undergoing complicated developments in Vietnam and around the world. The amount of information about the COVID-19 pandemic is enormous, especially in cyberspace, where people can create and share information quickly. This can lead to an "infodemic," which is a challenge every government might face in the fight against pandemics.


This study aims to understand public attention towards the pandemic (from December 2019 to November 2020) through 7 types of sources: Facebook, Instagram, YouTube, blogs, news sites, forums, and e-commerce sites.


We collected and analyzed nearly 38 million pieces of text data from the sources listed above via SocialHeat, a social listening platform developed by YouNet Group. We described not only public attention volume trends, discussion sentiments; top sources, top posts that gained the most public attention, and hot keyword frequency; but also hot keywords’ co-occurrence as visualized by the VOSviewer software tool.


In this study, we reached 4 main conclusions. First, based on changing discussion trends regarding the subject of COVID-19, 7 periods were identified based on events that can be aggregated into two pandemic waves in Vietnam. Second, community pages on Facebook were the source of the most engagement from the public. However, the sources with the highest average interaction efficiency per article are government sources. Third, people’s attitudes when discussing the pandemic have changed from negative to positive emotions. Fourth, the type of content that attracts the most interactions from people varies from time to time. Besides that, the issue-attention cycle theory occurred not only once but four times during the COVID-19 pandemic in Vietnam.


Our study shows that online resources can help the government quickly identify public attention to public health messages during times of crisis. We also determined the hot spots that most interested in the public as well as public attention communication patterns, which can help the government get practical information to make more effective policy reactions to help prevent the spread of the pandemic.
