The past few decades have seen a massive increase in the number of international organizations focusing on global health. Campaigns to eradicate or stem the spread of AIDS, SARS, malaria, and Ebola attest to the increasing importance of globally-oriented health organizations. These organizations may be national, regional, international, or even non-state organizations-like Medicins Sans Frontieres. One of the more important recent trends in global health governance, though, has been the rise of public-private partnerships (PPPs) where private non-governmental organizations, for-profit enterprises, and various other social entrepreneurs work hand-in-hand with governments to combat specific maladies. A primary driver for this development is the widespread belief that by joining together, PPPs will attack health problems and fund shared efforts more effectively than other systems. As Chelsea Clinton and Devi Sridhar show in Governing Global Health, these partnerships are not only important for combating infectious diseases; they also provide models for developing solutions to a host of other serious global health challenges and questions beyond health.
