The COVID-19 pandemic and the associated infodemic – the abundance of information, both true and false, spreading at unprecedented speed and scale – has created myriad challenges for public health professionals. In this webinar, speakers from Alliance member UC Berkeley’s School of Public Health will discuss their view that information environments are social determinants of health and describe their vision for how local infodemiologists – field epidemiologists for the infodemic – can begin addressing misinformation and building healthy information environments in their communities.
