Infodemia global. Desórdenes informativos, narrativas fake y fact-checking en la crisis de la Covid-19 // Global infodemic: Information disorders, false narratives, and fact checking during the Covid-19 crisis

Covid-19 has triggered not only a pandemic that endangers our social, economic, and health systems but also an infodemic resulting from the prolific spread of fake news, hoaxes, and misleading content. From a statistical-descriptive perspective and using content analysis, this research analyzes the information disorders, media language, and narratives that carry the disinformation generated about Covid-19 at an international level. The analysis focuses on determining its frequency of occurrence, based on the time it takes to be verified and establishing the relationship between the spread of the virus and the prevalence of disinformation on different continents. A sample of 582 fake news items included in the International Fact-Checking Network (IFCN) database on the novel coronavirus was analyzed. This information was divided into a general sample made up of 511 pieces of disinformation and a specific one on fake news spread throughWhatsApp (n=71). The results partially confirm recent studies that reported a greater prevalence of information that reconfigures legitimate content and takes longer to be verified than fully fabricated content. Disinformation in textual form predominates over the production of images and audios. Video content required longer verification times in comparison with the other media formats. Disinformation about Covid-19 includes narratives with a dynamic and changing character as the pandemic expands. Likewise, a parallelism between the geographical evolution of the pandemic and the spread of the infodemic is detected, as well as specific disinformation patterns on WhatsApp, where more audio-based disinformation and a higher percentage of fabricated content is shared, sometimes for criminal purposes
