La comunicazione pubblica della salute tra infodemia e fake news: il ruolo della pagina Facebook del Ministero della Salute nella sfida social al Covid-19

The year 2020 will be remembered as the year of Covid-19 pandemic, but also as the year of the infodemic, a condition of overabundance of information, some accurate and some not, that makes it hard for people to find trustworthy sources and reliable guidance. The state of uncertainty determined by an unknown virus has fueled citizens’ need for reassurance, and therefore for knowledge and information.
