In 2011, when medical doctor and epidemiologist Mark Smolinski was working as a science advisor for the blockbuster film “Contagion,” the film ran a campaign that asked communities: “What are you gonna do to prepare for the next pandemic?” A decade later, as the president of Ending Pandemics–a social venture that aims to predict, detect, and prevent disease outbreaks on our planet– Mark is still thinking about how we can rid the world of pandemic disease. In this episode, Mark shares why we use big data to track disease, explains how our interconnected ecosystems shape public health, talks about why ending pandemics is an achievable goal, and argues that local communities are the ones who can lead the way in understanding–and preventing–the spread of illness.
