How infodemic intoxicates public health surveillance: from a big to a slow data culture

Abstract

Too much data? Too much information? The COVID-19 pandemic has made the case. The WHO coined the term 'infodemic' to describe the issue of overabundance of information, including misinformation, disseminated in real time via multiple channels. 1 2 A related concept is 'datademic' to describe the overabundance of data. I argue in this essay that infodemic intoxicates public health surveillance and decision-making, and that we need to revisit how we conduct surveillance in the age of big data by fostering a slow data culture.
