Chan's School of Public Health, The World's reporter Elana Gordon moderated a discussion with Michael VanRooyen, director of the Harvard Humanitarian Initiative, about the dire situation and the multiple health risks that refugees from Ukraine, and from around the world, face. VanRooyen is also the chairman of Emergency Medicine at Brigham and Women's Hospital (@HHI).
