About this episode:
On December 3, the Bloomberg American Health Initiative held its annual summit. This year, the theme really marked the moment: Advancing Public Health in Uncertain Political Times. In today’s episode, you’ll hear three conversations from the Summit about how public health can provide a roadmap for making needed progress. First: how public health data and evidence provide context for judicial decisions. Then, how a public health lens is helping to address the issue of gun violence. And finally, how to find common ground on mental health and addiction.

828 - Public Health is a Human Right
About this episode:
The day after the 2024 presidential election, Joe Amon—the brand new director of the Johns Hopkins Center for Public Health and Human Rights—was set to give a speech for a panel about health discrimination. But the one he’d prepared wasn’t going to cut it for a moment suddenly marked by uncertainty and change. He pivoted to a different message: one that acknowledges that public health doesn’t have everything figured out, and that it works best when it’s viewed as a social movement. In this episode: a moment of reflection for the field, considerations of some of the challenges that lay ahead, and the critical importance of thinking about public health as a human right. Note: You can read an adaptation of the speech in the link below.

823 - Special Episode—The Fight For A Swimmable Harbor in Baltimore
About this episode:
Baltimore’s iconic Inner Harbor is like a highway for massive ships. It’s also been a dumping ground for chemicals and pollutants, and every time it rains, stormwater runoff brings sewage and trash from miles inland. But in 2010, a coalition announced the Healthy Harbor initiative—a plan to make Baltimore’s famous waterfront swimmable and fishable by 2020. In June 2024, the city held its first public swim in the harbor in more than 40 years. It took nearly a decade and a half to pull it off—and some say, it’s only the beginning. In this special episode of Public Health On Call, we look at four ways Baltimore activists, coalitions, agencies, scientists, and residents came together to fight for a swimmable and fishable harbor: getting people’s attention, collecting data, mitigating sewage, and battling against trash.

Lindsay Smith Rogers, MA, is the producer of the Public Health On Call podcast, an editor for Expert Insights, and the director of content strategy for the Johns Hopkins Bloomberg School of Public Health.
