In his newest book, Sandro Galea emphasizes that the field of public health is committed as much to preventing disease as to treating it. Public health includes the social factors that frame our lives. This includes social inclusion, economic security, political stability, adequate diet, access to education, and other factors that frame an individual’s life. Dr. Galea discusses the necessity of rational policies that create social stability and comfort. Developing the foundation for genuine public health requires more effective communication –and elimination of misinformation and vitriol-- in a process he calls radical incrementalism.
