Bloomberg health summit gets underway 

The Bloomberg American Health Initiative — which is aiming to tackle five key health issues affecting U.S. health — is holding its second annual summit today and tomorrow at Johns Hopkins’ Bloomberg School of Public Health, where the initiative is based. The five issues that will be examined are addiction and overdose; environmental challenges; obesity and the food system; risks to adolescent health; and violence. This year’s summit will feature experts whose work covers various aspects of the focus areas, but will notably also include a video message from the “Sesame Street” muppet Karli, whose mother struggles with addiction. And although most of the summit is invite-only, today’s morning plenary — featuring the president of the March of Dimes and others — will be livestreamed starting at 8:30 a.m. ET.
