Global health, international health and public health: which relationship?

The international scientific community has recently seen a growing debate on global health, and what similarities exist between this, public health and international health. Going through the definitions of global health found in the literature, we will highlight points of contact and differences, and discuss the definition of global health provided by the Italian Network Global Health Education. Finally, we will stress the need to incorporate the global health approach in the training of future medical doctors,in particular public health specialists, with the aim of providing current and future health professionals with the skills to deal with the challenges posed by globalization at the local level.
