Were our public health systems misunderstood before COVID-19?

We're in a very strange time right now, where public health has suddenly become a major focus in a way that doesn't happen very often, and as a result, the people who work in public health have also become more visible than probably we or they ever expected them to be. Dr. Fauci and Dr. Birx are nationally recognized household names now, and each state has its own team of doctors and public servants who find themselves at the podium for hours a day, giving out information to anyone watching. Because of the spotlight on public health right now, we wanted to dig into it a little more. Dr. Tony Reed, Chief Medical Officer for Temple University Hospital joins KYW In Depth to explains what the field of public health entails and what's involved in working a public health job.  See omnystudio.com/policies/listener for privacy information.
