It's another edition of the Midday Healthwatch, our monthly conversation with Baltimore City Health Commissioner Dr. Leana Wen. She’ll bring us up to date on the city’s continuing battle with the twin epidemics of violence and drug abuse. We’ll also talk about health insurance. Record numbers of Marylanders are signing up under the Affordable Care Act. How the city’s B’more for Healthy Babies initiative is giving babies a healthy start. And, despite record high temperatures today, it’s Code Blue season. How are some of our most vulnerable citizens going to stay safe this winter?
